3D RECONSTRUCTION SYSTEM AND METHOD UTILIZING A VARIABLE X-RAY SOURCE TO IMAGE DISTANCE |
摘要 |
A medical imaging system comprises a C-arm unit (112) having an x-ray source (123) for generating x-rays and a receptor (124) for obtaining image exposures from received x-rays. The C-arm unit (112) moves the x-ray source (123) and receptor (124) along an image acquisition path between at least first and second exposure positions. The C-arm unit (112) rotates about a central axis (133). Source and receptor brackets (127, 131) mount the x-ray source (123) and receptor (124), respectively, to the C-arm unit (112). The source and receptor brackets (127, 131) move at least one of the x-ray source (123) and receptor (124) in a radial direction toward and away from the central axis (133) of the C-arm unit (112) to maintain a desired distance between the patient (22) and the x-ray source (123) and receptor (124). An image processor (16) collects a series of image exposures (32) from the receptor (124) and constructs a three dimensional volumetric data set which is displayed on a display (250).
