A fluoroscopic tomography system capable of synthesizing body sections at a number of levels within the body has been developed. The synthesized body sections may lie either in a range of planes parallel to, tilted with respect to, skewed with respect to, or both tilted and skewed with respect to the plane of motion of the X-ray tube target. In addition, body sections can be presented which are contoured to the patient's anatomy. That is to say, they may even encompass such complex surfaces as a quadratic hyperplane. In addition, tomograms of organs in motion can be imaged.
The authors describe a fluoroplanigraphic method of synthesizing single-plane sections of any desired layer within the body. This is done by appropriate positioning of the individual images obtained at various locations of the X-ray tube during a single tomographic motion, followed by electronic summation of each roentgenogram. A TV image of any desired body section is available within seconds of the original recording sequence.
