Test 8: Acquisition Workstation Monitor Check

Objective

To assess the quality of the acquisition workstation monitor.

Required Equipment

SMPTE test pattern (provided in syngo)
a)

Procedure

1. Clean the monitor
a) The monitor surface should be cleaned with a soft tissue material, such as
cotton or lens cleaning paper.
b) If necessary, stubborn stains can be removed by moistening part of a cloth
with water to enhance its cleaning power.
Select the Viewing task card.
3.
4. Open the Patient Browser, select Service images, technical images.
Open the SMPTE in the Viewing task card. Make sure that the SMPTE covers
5.
the entire viewing area, e.g. the window should not be divided in four viewing
areas.
Check that the window center is set to 2048. Check that the image is displayed
in acquisition size under Image > Acquisition Size.
6. The gray scale is shown as a series of squares in the center of the SMPTE image,
ranging from black (0%) to white (100%) in a rectangle. The 0% and 100%
squares each contain smaller squares within them that represent a signal level of
5% and 95% respectively (see Figure 9). You should be able to differentiate the
inner square from the corresponding outer square. The 5% square is normally
quite difficult to differentiate. If the viewing conditions are considered to be
inferior, perform this test again with dimmed room light.
