Title:
放射線画像処理装置、方法およびプログラム
Document Type and Number:
Japanese Patent JP7266543
Kind Code:
B2
Abstract:
A processor detects a surgical tool from a radiographic image acquired by irradiating a subject with radiation emitted from a radiation source and detecting the radiation transmitted through the subject with a radiation detector. The processor measures a size of the detected surgical tool on the radiographic image. The processor derives a position of the surgical tool in a height direction in the subject on the basis of an actual size of the surgical tool, the measured size, and a geometrical positional relationship between a position of the radiation source and a position of a detection surface of the radiation detector.
