FLUOROSCOPIC QUALITY CONTROL TEST TOOL*
For Fast Operational Checks of....
Fluoroscopic system resolution.
Proper brightness and contrast adjustment of video monitor (both
permanent and mobile).
Off-center image sharpness.
Spot film image density, uniformity, and resolution.
Resolution of video tape recorder, or last-image-hold
system.
A major problem in most fluoroscopic systems is the misadjustment of the
contrast and brightness controls of the fluoroscopic or video monitor. The
Fluoroscopic QC Test Tool provides a precise, accurate, easy-to-use means of
quickly checking the image quality of permanent and mobile systems, including
video tape recorders and last-image-hold systems, which are becoming widely used
in fluoroscopic imaging.
The test tool consists of light and dark low contrast test objects for
monitor
adjustment, copper mesh for image sharpness, and resolution pattern for system
resolution. It can also be used to evaluate fluoroscopic resolution and
off-center image sharpness, as well as the density, uniformity, contrast, and
resolution of spot film images (conventional spots, 105 mm spots, or digital
spots).
