Title:

TREATMENT SYSTEM, CALIBRATION METHOD, AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2020/022420

Kind Code:

A1

Abstract:

The treatment system according to an embodiment of the present invention includes a first acquisition unit, a second acquisition unit, a first derivation unit, a second derivation unit, a calibration unit, and an imaging system comprising a plurality of detection units and one or more radiation sources. The radiation sources irradiate radiation from a plurality of directions that are different from one another, onto an object. The plurality of detection units detect the radiation at positions that are different from one another. The first acquisition unit acquires a radiation-based image. The second acquisition unit acquires positional information of the first imaging machine in three-dimensional space. The first derivation unit derives the object position in the image. The second derivation unit derives the second imaging machine three-dimensional space position or the like on the basis of the object position in the image and the first imaging machine position or the like. The calibration unit calibrates the imaging system on the basis of the derivation result from the second derivation unit.
