Title:
METHOD TO DISPLAY X-RAY FRAME SEQUENCE AUTOMATICALLY AND NON-AUTOMATICALLY
Document Type and Number:
Japanese Patent JP3540347
Kind Code:
B2
Abstract:
PURPOSE: To obtain an easy diagnosis by allowing to generate a series of images which can freeze a confirmed a frame of feature by tracking automatically a confirmed feature within one frame by the subsequent frame relating to a fluorescent X-ray photographic system suitable for observing disorders of cardiac vessels.
CONSTITUTION: The radiogram of a patient 10 irradiated from an X-ray source 11 launches into an input light emitting body 13 of an intensifier 12 and the obtained electron beam image is converted into a bright lightwave image by an output light emitting body 14. This lightwave image is observed by a video camera 15. After the analog video signals are converted to digital signals 17, they are fed to the video processor DVP 19 and a scanning line forming a complete X-ray image frame is stored. In DVP-CPU 27, under control of host CPU 25, a confirmed feature moving within a series of the X-ray frame is automatically tracked and not only the feature is automatically picked up within the subsequent frame, but also a series of images containing the feature in the center, are generated substantially in a standstill state.
