Radiation measurement apparatus and radiation measurement method

摘要

A radiation measurement apparatus includes: a radiation detector which detects incoming radiations; a measurement processor which measures a distribution of a radiation source in an object on the basis of detection signals inputted from the radiation detector; an optical camera which takes an optical image of an object existing in the field of view; a controller which generates synthesized images by superimposing the distribution of the one or more radiation sources and the optical image; a rotation unit which changes the objective field of radiation measurement by automatic or manual rotation; and a controller which causes a display unit to display the multiple synthesized images in association with rotation angles in the automatic or manual rotation.

1. A radiation measurement apparatus comprising:
a gamma camera which detects incoming radiation in a first field of view and measures a distribution of the radiation in the first field of view; an optical camera which takes an optical image in a second field of view; a rotation unit to which the gamma camera and the optical camera are connected, and which allows the gamma camera and the optical camera to rotate together while maintaining a location thereof so that the first field of view and the second field of view correspond to a plurality of objective fields; a processor connected to the gamma camera, the optical camera, and the rotation unit; and a storage medium which stores instructions that, when executed by the processor, cause the processor to: generate a plurality of radiation distribution images with the gamma camera in association with rotation of the rotation unit, where the radiation distribution images correspond to different one of the objective fields, take a plurality of optical images with the optical camera which is rotated together with the gamma camera in association with rotation of the rotation unit, where the optical images correspond to said ones of the objective fields, generate a plurality of synthesized images by superimposing the radiation distribution images and the optical images, where the synthesized images correspond to said ones of the objective fields, generate a panoramic image including each of the objective fields by concatenating the synthesized images, calculate a spatial dose rate of the radiation in the panoramic image, and display, in association with rotation angles of the rotation unit, the panoramic image on a display device, wherein the panoramic image represents a 360° view of the objective fields.
