Patent ID: 7706505

Claim:
A wireless X-ray fluoroscopic imaging system comprising: an X-ray generation unit configured to perform X-ray exposure for each frame of fluoroscopic imaging; a sensor unit including a sensor configured to convert X-rays of the X-ray exposure into charge distribution information and output the information as image data; and an image processing unit configured to designate the exposure by said X-ray generation unit, and receive the image data from said sensor unit, wherein said sensor unit and said image processing unit communicate with each other via a wireless link, said sensor unit includes a first counter configured to be reset and resume counting in response to a beacon signal communicated via the wireless link, and a unit configured to save a counter value corresponding to a readout trigger offset which defines a time from start of the frame to start of readout of the image data, and starts the readout when a counter value of said first counter matches the saved counter value corresponding to the readout trigger offset, and transfers the readout image data to said image processing unit via the wireless link, and said image processing unit includes a second counter configured to be reset and resume counting in response to the beacon signal of the wireless link, and a unit configured to save a counter value corresponding to an exposure trigger offset which defines a time from start of the frame to start of the exposure, and starts the exposure when a counter value of said second counter matches the saved counter value corresponding to the exposure trigger offset.
