Title: Apparatus and method for computerized tomography
Inventor: BRUDER HERBERT
IPC: G01N23/04
Filed: 2002-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a means for computerized tomography which makes it possible to fit a detector array largely spreading toward an axial line of the system, thereby enabling the aquisition of quality images. SOLUTION: Since an object is scanned by a matrix-type detector array for detecting a radiation bundle generating from a focus F, the focus is moved on a spiral orbital path S around an axial line of the system relatively against the object, and an output data supplied between the focal movements on the spiral orbit is divided into the output data relating to the subsegment where the length of the subsegment is made shorter than that required for the reformation of respective CT images.
