Abstract
A fluoroscopy machine allows programming of a frame rate in the range of multiple seconds per frame and then displays the images at a higher rate in a loop in the radiological theater so as to impart an improved sense of motion to a human observer of a slow physiological processes captured by fluoroscopic studies.
Claims17
A fluoroscopy machine comprising:
- a gantry system holding:
- (a) an x-ray source operable to provide discrete x-ray exposures according to a control signal;
- and
- (b) an image intensifier opposite the x-ray source to receive x-rays from the x-ray source during the discrete x-ray exposures and to provide image data:
- an input for receiving instructions from a fluoroscopy machine user;
- a display for receiving the image data:
- and
- a fluoroscopy control circuit communicating with the x-ray source, image intensifier, and display and operating to:
- (a) receive instructions through the input identifying an acquisition frame rate in a range providing multiple seconds between each frame:
- (b) control the x-ray source and image intensifier to acquire a set of time-ordered images at separated acquisitions at the acquisition frame rate;
- and
- (c) provide a looping display on the display of the set of time-ordered images in sequence according to a display rate different from the acquisition frame rate.
