11. RTVA Image Processor
The RTVA (Real-Time Video Averager) is an image processor used in the XR
2000 X-ray system. It uses video frame averaging to smooth the inherently
grainy image coming from the X-ray camera. It is located inside of the XR 2000
housing.
The RTVA is adjustable by using the front mounted switch marked "FRAME
AVERAGING". See Figure 3. This adjusts the amount of frames that the RTVA
averages before sending the video out to the monitor. When using the switch,
please note the following frame averaging settings:
(Note that image trailing will occur at higher settings.)
Setting
The RTVA image processor also has a "CAPTURE" ability that is designed to
hold the current image. To use this option, just switch the front-mounted
CAPTURE/LIVE switch to the "Capture" position. See Figure 3. To return to
normal operating mode, return the switch to the "LIVE" position.
Please note that there are no user serviceable components inside. If the
component is suspected of being faulty, please call PACE.
