Poor photography will cause loss of low level echoes and the

lack of contrast between large amplitude echoes. See

Figure 18-11 for more information.

When photographic controls and film processors are properly

adjusted, weak echoes, as well as strong echoes, are accurately

recorded on film.

1. Adjust the camera according to the manufacturer's

instructions until the hard copy and video display are equal.

2. Scan the phantom and it's echogenic contrast targets.

3. Make a hard copy photograph of the display and compare it

to the image on the video monitor for contrast and weak

echo display.

4. Document all results for future reference and comparison.

Contact a Service Engineer if camera cannot duplicate what is

on the image monitor.

Optimization of brightness/contrast controls on the display

monitor is imperative in order to make sure that the hardcopy

and monitor look alike.

The display monitor is adjusted first. The hardcopy camera or

printer is adjusted to match the display monitor.
