Gray Scale photography
Description
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.
Benefit
When photographic controls and film processors are properly
adjusted, weak echoes, as well as strong echoes, are accurately
recorded on film.
Procedure
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.
