Vevo F2 Imaging System User Manual M-Mode and AM-Mode Motion mode (M-Mode) shows how a section of a 2D image changes over time, relative to a line laid over the image. It is primarily used to measure the movement and dimensions of cardiac structures such as the heart chambers and vessel walls. For example, it can be used to view a cross-section of a heart, and view how the heart cross-section moves over time, relative to the line. While B-Mode is a frame-based mode that uses multiple scanning beams, M-Mode is a time-based mode that uses just one beam. Anatomical M-Mode (AM-Mode) is a modification to M-Mode that allows the user to capture the sample volume at an angle, rather than capturing the sample volume in a strict vertical position. It is mainly used in echocardiography to obtain anatomically correct visualizations and measurements of the left ventricle. Unlike M-Mode, which acquires data along a single acquisition line, AM-Mode data is re-constructed from acquired B-Mode data, based on the ultrasound grayscale information along the sample volume line. To use AM-Mode, adjust the angle of the gate using the AM-Mode Angle control. The system will automatically switch to AM-Mode.

Vevo F2 Imaging System User Manual Nonlinear Contrast Mode Nonlinear Contrast (NLC) Mode is a high-frequency imaging mode that produces improved sensitivity in microbubble detection and quantification. This mode uses a pulse inversion imaging scheme to suppress the tissue signal while enhancing the detection of the contrast agents. To generate Nonlinear Contrast Mode images, you need to use contrast agents. For more information, refer to Contrast Agent Technology below. This mode is only available with certain transducers. For a list of transducers and compatible modes, refer to Transducer Compatibility Chart on page 418. Contrast Agent Technology Nonlinear Contrast Mode imaging requires the use of contrast agents. Contrast agents are gas filled microbubbles that produce a strong echogenic signal when excited with an ultrasound pulse. FUJIFILM VisualSonics provides a family of contrast agent kits for targeted and nontargeted a pplications. Non-Targeted Contrast Agents Non-targeted contrast agents are injected into the vascular system either as a s mall bolus or continuous infusion using an infusion pump. The contrast agents are free flowing in the vascular system for a period of time until they are either destroyed with a high-powered ultrasound sequence or are cleared through the system via the kidney and the liver. Targeted Contrast Agents Targeted contrast agents are microbubbles similar to those used in non-targeted applications, but are conjugated with a ligand that will bind to specific molecular m arkers. A targeted contrast agent flows freely through the vascular system until it finds the specific receptor. At this time it binds to the molecular marker on the endothelial surface of the vessel and will no longer flow freely.

Vevo F2 Imaging System User Manual 4D-Mode 4D-Mode is a three-dimensional EKV (ECG-based Kilohertz Visualization) Mode image of one complete cardiac cycle, synthesized with B-Mode image data acquired at a high frame rate. To produce a 4D-Mode clip, the ultrasound system uses the 3D motor to move the transducer across the target object in a series of steps. For each step, the system acquires EKV data of one complete heart cycle. The total data from all of these steps is then compiled to create a 4D-Mode clip of one heart cycle. When scanning in 4D-Mode, please note: 4D-Mode is only available when acquiring data in B-Mode. An ECG signal is required to acquire 4D-Mode images. If the ECG signal fails while acquiring data for 4D-Mode, the system will stop acquiring data, and an error will be displayed. 4D-Mode uses the same analysis tools as 3D Mode, except in 4D-Mode these tools can be applied across different points of time. When using imaging modes that do not support 4D-Mode, the Cube tab is still available on the control panel to provide access to 3D Mode controls, and to control the 3D motor. 4D-Mode Hardware Setup To acquire 4D-Mode data, the following things must be properly set up: A Vevo Imaging Station A Vevo Animal Monitoring System A 3D motor attachment for the Vevo Imaging Station For detailed instructions about setting up these components, refer to the Vevo Integrated Rail System Operator Manual and the Vevo Animal Monitoring System Manual.

Vevo F2 Imaging System User Manual VADA Mode Vevo Advanced Data Acquisition (VADA) Mode is a unique mode specifically designed for ultrasound research. It provides individual raw channel data from the transducer, before the data has been processed to create an ultrasound image. VADA Mode provides raw channel data, taken before any processing steps Unlike other modes, VADA Mode does not display image data on the image display because it is a data acquisition mode, and the acquired data is not reconstructed. Instead, VADA Mode displays raw channel data on the image display.

Enabling or disabling trigger events. Applying any other settings to the system. For more information about the VADA configuration panel, refer to Navigation on page 251. Hardware Limitations While VADA Mode aims to provide full customizability over the system, certain settings may not be possible due to hardware limitations. For example, certain elements cannot be set to fire at the same time during system transmit and receive. Transducer Thermal Management In standard imaging modes (B-Mode, PA-Mode), the Vevo F2 has been calibrated with acoustic power and intensity tests to prevent the surface of the transducer probe from exceeding 50°C while imaging in air without coupling materials. While some limits have been put in place for pulse sequences in VADA mode, it cannot be guaranteed that a given pulse sequence will not induce dangerous levels of heating due to a combination of voltage, pulse repetition interval (PRI), aperture, transmit waveforms and imaging session length. To minimize the chance of heating issues, FUJIFILM VisualSonics recommends running all sequences at the lowest voltage setting that will achieve the desired data output. Perform thermal validation of all sequences using a thermocouple or some other thermal measurement equipment before using them in experiments. Known Causes of Increased Transducer Heating Although full thermal models are difficult to derive for all VADA pulse sequences, particular combinations of parameters have been found to be more likely to cause increased heating of the transducer surface. Be aware that the following characteristics are known to cause transducer heating: Low PRI (Especially very shallow imaging depths, or disabling the Display Channel Data setting in the Preview tab of the VADA Configuration Panel) Long transmit waveforms Large, stationary apertures Very long pulse sequences, particularly on the L38xp...

For example, "1:32, 64:128" means all elements between 1 and 32, and all elements between 64 and 128. Constant Offset: Sets a constant offset for the elements specified in the Elements field. I n consecutive increments, it is important to position the Tx and Rx elements relative to each other (because they are defined as 1:128/1:64), to allow for the absolute positioning of the base elements. Variable Offset: (Only available when the Tx/Rx event is within an Element Loop) Sets whether the Element loop offset is added to the constant offset when calculating offset increments. This is a drop- down list with two choices: Loop: Loop Name: Adds the offset specified in the Element Loop settings to the Constant Offset value. None: Uses only the Constant Offset value.

If this check box is selected, the block enables the Q-Switch. If this check box is selected, the block disables the Q-Switch. Enabling the Q-Switch does not cause the Vevo LAZR-X laser cart to start firing. It allows the laser to fire based on a trigger input. The Vevo LAZR-X laser cart operates by sending a trigger to the Vevo F2 and receiving a delayed trigger from the Vevo F2. A typical pulse sequence to fire the laser system would involve: 1. Q-Switch: Enable block 2. Trigger Out block 3. Trigger In block 4. Tx/Rx Event block Once the Vevo F2 receives a trigger signal from the laser as a "Trigger In" signal, it continues onto the Tx/Rx Event. The "Trigger In" block is setup with a delay (typically 180-200 us), which causes the Vevo F2 to send a "Trigger Out" signal to the laser system and also start to transmit/receive after the specified time.

Vevo F2 Imaging System User Manual Settings Display Channel Data: Toggles whether received channel data is displayed on the preview graph. If this setting is off, the transmit can be repeated much faster (approximately 50x faster or more) than with it on. This is useful for hydrophone measurements. When this setting is off, the "capture data" button changes to read "transmit data" because the transducer is transmitting data without processing it to display on the graph. Caution: Be aware of thermal considerations when turning off Display Channel Data. This is because the transmit rate is much higher when it is off. For more information, refer to Transducer Thermal Management on page 237. Use Minimum PRI: Select this setting to make the transducer fire as often as it can. The firing rate varies depending on whether channel data is displayed, and the depth of the signal.

Overwriting Precautions When you save a preset with a name that already exists, you overwrite all settings previously saved on that preset name.

To avoid overwriting settings in this way, be aware of all settings in all modes (not just the currently selected mode), or make sure to use different preset names for different modes.

Note About Changing Configuration Files and Transducers When a user creates or modifies a VADA configuration file for a specific transducer in Vevo LAB, that configuration file can be applied to any transducer when imported into a Vevo F2 system. The configuration file may not work correctly when imported to a different transducer, because of issues such as the waveform frequency being incompatible between transducers. For example, taking a configuration file created for a UHF22x and using it on a UHF71x may not work, as the number of receive elements per transmit/receive event differ between the two transducers. Therefore, when selecting a configuration file for a transducer that is different from the transducer it was created for, the user should verify that the pulse sequence is compatible with the transducer it is being used for.

Do not remove any panels from the Vevo F2 Imaging System. Do not r emove the outer transducer housing. Service to the system is to be performed by qualified personnel only. No user-serviceable parts are located inside the system. Any internal adjustments, replacements or modifications to the Vevo Imaging System e lectronics or to the transducers should be made only by qualified FUJIFILM VisualSonics T echnical Support Representatives. If the system is not properly grounded or earthed, it becomes a p ossible electrical shock hazard. Protection against electrical shock has been provided t hrough an isolation transformer and chassis grounding via a plug to an appropriate p ower source. DO NOT remove the ground wires from any part of the Vevo F2 Imaging System for any r eason.

F UJIFILM VisualSonics. Connection of accessories and peripherals not recommended by F UJIFILM VisualSonics could cause your ultrasound system to malfunction, or cause other medical e lectrical devices in the area to malfunction. The use of accessories, transducers and cables other than those s pecified (with the exception of transducers and cables sold by FUJIFILM VisualSonics as r eplacement parts for internal components) may result in increased emissions or d ecreased immunity of the Vevo F2 Imaging System. DO NOT situate the Vevo F2 Imaging System close to large clinical m agnets, as the magnetic fields may affect performance a nd c ause distortions in the acquired image.

Ergonomics The height of the Vevo F2 Imaging System is not adjustable. Users who find standing at the system uncomfortable may require an adjustable chair or stool. Users may find hand-scanning with a transducer uncomfortable when used for long periods of time. Users are advised to use the transducer mounting system if they experience discomfort. Laser Safety General The Vevo LAZR-X laser cart uses a Class 4 laser, which is the highest and most dangerous classification. When working with the laser, take precautions to minimize possible exposure to both direct and reflected beams. Do not alter the laser for any reason. Maintenance on the laser should only be performed by a FUJIFILM VisualSonics Service Technician. If you modify the laser, you assume the risk that is associated with a Class 4 laser. Do not use the laser in a manner not specified by the manufacturer or by this manual. For a complete listing of laser safety standards, FUJIFILM VisualSonics recommends reading the American National Standard for the Safe Use of Lasers and implement necessary precautions (ANSI Z136.1-1986). Contact the Laser Institute of America for more information. Laser Safety Always wear laser protective eyewear of sufficient optical density and suitable wavelength to protect the eyes from the maximum energy produced. Direct eye contact with the laser beam can cause permanent eye damage. Diffuse and specular reflections from the main beam can cause severe eye and skin damage. Infrared radiation can pass easily through the cornea into the retina, where it can cause ...
Page 465
Vevo F2 Imaging System User Manual The laser must be stored and used in a locked area that can only be accessed by authorized personnel. Keep all unnecessary personnel out of the work area. Keep all reflective surfaces (such as rings, watch bands, metal pencils, etc.) away from the work area. Keep all flammable/volatile materials and containers away (which the laser could ignite) from the work area. Operate lasers under the supervision of qualified personnel only. When not in use, shut down the laser completely. Keep the laser firing area well lit so that the pupils of worker's eyes will naturally constrict. This reduces the amount of light entering the eye, reducing the potential for eye damage. Place a fire-resistant background behind the target area. Coat the area surrounding the laser with a material that absorbs any scattered radiation that might occur. Never leave the laser running unattended. Never track individuals, vehicular traffic, aircraft or any airborne objects by means of laser radiation. Electrical Safety To prevent electrical shock, ensure that the capacitors are completely discharged and the power is turned off before performing any cleaning or disinfecting to the laser. Electric shock and burns resulting from input power or capacitor discharge can cause serious injury or death. Be aware that high voltages are present in the laser heads once AC power is turned on. ...
Page 466
Vevo F2 Imaging System User Manual All interlocks must be OK before the laser will fire. If any interlock is tripped, including the external interlock, the amber INTERLOCK LED will turn on, and the laser will stop firing. The interlock must be reset before the laser can be restarted. You may also wire the laser so that opening a door to the laser imaging room (or opening any other switch) will shut off the laser. Laser Covers The LAZR-X laser has a safety cover over the optics area. This cover must be in place during operation. Shutters An intracavity safety shutter interrupts the beam and prevents lasing when the laser is not in use. There is also a shutter at each of the two fiber ports to block the laser when a fiber is not plugged in. Never try to open the shutters if a fiber is not plugged in. Beam Dumps There is a beam dump at each side of the laser. They must be in place to block invisible and visible laser radiation. Safety Labels The following table describes the safety symbols that appear on the laser. Symbol Publication Description IEC 60417 - 5007 On (supply). IEC 60417 - 5008 Off (supply).
