METHOD FOR FORMING CT IMAGE AND X-RAY CT APPARATUS

摘要

PROBLEM TO BE SOLVED: To rapidly form a CT image. SOLUTION: A master processor MP converts fan view data obtd. by each X-ray detector to paraview data and distributes them to slave processors SP1-SP4. In addition, correcting data B1-B4 are sent duplicatedly to the slave processors SP1-SP4. The slave processors SP1-SP4 perform consistently from the first pretreatment to the aftertreatment to produce BP data i1-i4. The master processor MP collects the BP data i1-i4 and forms a CT image. As it is possible thereby to perform consistently from the first pretreatment to the aftertreatment by the slave processor, it is possible to shorten treating time as a whole and to form the CT image more rapidly.
