Interactive X-ray position and exposure control using image data as reference information

摘要

An X-ray system and method for use in a medical application to supplement or replace fluoroscopy is described. The X-ray system includes a display device (110), a gantry (130) having an X-ray generator (132), a table (140) having an X-ray sensor (142), and an X-ray control system(120) connected to the display device (110), the gantry and the table. The X-ray control system (120) includes user input (122) for indicating the position of the next X-ray exposure. The X-ray control system (120) receives X-ray data from the sensor (142), processes the data to form an X-ray image, displays the X-ray image on the display device (110) and shifts the X-ray generator (132) relative to the X-ray sensor (142). The amount and direction of shift is accurately determined using data from the previous X-ray image.
