Title:
Ｘ線ＣＴデータ処理装置、及び、これを搭載したＸ線ＣＴ装置
Document Type and Number:
Japanese Patent JP6539748
Kind Code:
B2
Abstract:
An X-ray CT data processing device is provided which when multi-energy photography is performed with an energy-separation type detector, and a subject is separated into a plurality of standard materials to create an image, estimates the appropriateness of posited standard materials, and in order to determine appropriate standard materials with satisfactory accuracy, processes CT data respectively acquired in a plurality of detection energy ranges to create a reconstructed image separated into predetermined standard materials. The X-ray CT data processing device is equipped with a standard material data calculating part which calculates energy-independent physical quantities for a plurality of standard materials respectively using different combinations of a plurality of the CT data, and creates a plurality of standard material data for the same standard material, and an appropriateness determination index creating part which creates an index for determining the appropriateness of the standard material, based on the plurality of standard material data calculated by the standard material data calculating part.
