COMPUTED TOMOGRAPHY AND TOMOSYNTHESIS SYSTEM

摘要

A computed tomography system adapted for tomosynthesis provides sectional and planar images comparable to conventional tomography and tomosynthesis but in a system that is less expensive, less complex, generally more reliable, as well as easier to operate. The computed tomography system, capable of tomosynthesis, includes an inner circular gantry and an outer gantry within a housing assembly. A plurality of spaced apart radiology plates are located along a surface of the inner circular gantry within the housing assembly and adapted as the x-ray detectors. An x-ray source device is secured to the outer gantry and adapted to shoot x-rays between the spaced apart phosphor surfaces and onto the patient or object while being rotated along the gantry and relative to the object. A radiography device is moveably coupled to the inner gantry and adapted to scan and read the radiology plates and provide the data to an image processing computer. The system is adapted such that the x-ray source device coupled to the outer gantry moves relative to the x-ray detectors such that a large number of projections can be exposed and thereafter immediately scanned by the integral radiology device.
