Poor photography will cause loss of low level echoes and the
lack of contrast between large amplitude echoes. Refer to
Figure 5–1 on 5–5 for details.
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.
NOTE: 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.
