    摘要: In a control apparatus for a radiotherapy apparatus, each of a plurality of separation results indicates an objective portion template and a non-objective portion template. The separation result is calculated such that a difference between a first template production image and an image produced by superimposing an objective portion template in a position of a designated region on the non-objective portion template is small and a difference between the second template production image and an image produced by superimposing the objective portion template in a position of an assumption region, which is different from the designated region, on the non-objective portion template.

    摘要: A radiotherapy device control apparatus includes: a template matching section; an affected area position calculating section; and an irradiation position control section. The radiotherapy device control apparatus controls a radiotherapy device. The radiotherapy device includes: a therapeutic radiation irradiation device radiating therapeutic radiation, and an imager generating an imager image of a subject by using radiation transmitted through the subject. The template matching section calculates degree of coincidence when a pattern matching is executed on the imager image with a plurality of image templates in which positional relations between an object area and a non-object area of the subject are different, and selects a specified image template having the degree of coincidence within a predetermined range from the plurality of image templates. The affected area position calculating section calculates a position of the object area by using the specified image template. The irradiation position control section judges whether a relative position of the object area with respect to the therapeutic radiation irradiation device. The irradiation position control section moves one of the therapeutic radiation irradiation device and a couch with the subject by using a drive device provided with the radiotherapy device such that the object area is irradiated with the therapeutic radiation.

    摘要: A radiation therapy device controller identifies a pixel on a straight line connecting a ray source and a sensor array, and calculates a luminance update amount candidate value for each identified pixel based on a ratio of a change amount for the pixel on the straight line indicating the living body to a sum of change amounts from a luminance value of a pixel corresponding to a correlated computed tomography image correlated with a computed tomography image of an update target of a luminance value of the identified pixel. Also, the control device calculates a luminance update amount of each identified pixel using the luminance update amount candidate value of each identified pixel calculated for a plurality of rotation angles, and updates the luminance value of each corresponding pixel of the computed tomography image of the update target using the luminance update amount of each identified pixel.

    摘要: This radiation therapy device controller selects, for a plurality of body motion phases, computed tomography image data obtained which shows a diseased portion, and generates, for each rotation angles of a ray source and a sensor array, a reconstructed image. The control device generates a radiation projection image which shows the diseased portion when the radiation is radiated if the rotation angle is a predetermined rotation angle, compares the reconstructed image of each of the plurality of body motion phases with the radiation projection image, and determines a body motion phase indicated by a reconstructed image in which a difference is small, to be a current respiratory phase. As a result, a position of the diseased portion calculated for the computed tomography image data in the computed tomography image data group of the respiratory phase in advance is identified to be a current position of the diseased portion.
