MEDICAL TREATMENT APPARATUS, CONTROL DEVICE AND CONTROL METHOD

摘要

According to an embodiment, a medical treatment apparatus includes: a first acquirer to acquire a group including five or more pairs of corresponding points on a first perspective image of a subject captured at a first timing and a second perspective image of the subject captured at a second timing; a second acquirer to acquire a first parameter including position/orientation information of an imaging device capturing the first perspective image and conversion information related to a coordinate system of the first perspective image, and acquire a second parameter including position/orientation information of an imaging device capturing the second perspective image and conversion information related to a coordinate system of the second perspective image; a calculator to calculate difference in position of the subject between the first timing and the second timing using the group and the parameters; and a controller to control a subject position using the difference.

1. A medical treatment apparatus comprising:
a first acquirer that acquires a first group including five or more pairs of corresponding points respectively on a first perspective image of a subject viewed in a first direction at a first timing and a second perspective image of the subject viewed in a second direction at a second timing being different from the first timing; a second acquirer that acquires a first parameter and a second parameter, the first parameter including position and orientation information of an imaging device that captures the first perspective image and including conversion information related to a coordinate system of the first perspective image, and the second parameter including position and orientation information of an imaging device that captures the second perspective image and including conversion information related to a coordinate system of the second perspective image; a calculator to calculate difference in position of the subject between the first timing and second timing using the first group, the first parameter, and the second parameter; and a controller that controls a position of the subject using the difference.
