Computer assisted radiotherapy dosimeter system and a method therefor
First Claim
1. A method of determining locations of radiation sensors in, on or adjacent a body during subsequent irradiation thereof by a radiation therapy system, comprising the steps of:
- (i) displaying on a display device, simultaneously, a representation of at least a portion of the body to be irradiated, and a plurality of graphics artefacts each representing a respective one of a plurality of radiation sensors to be positioned in, on or adjacent said body during subsequent irradiation of the body, each graphics artefact comprising a sensor icon and a sensor identifier;
(ii) controlling the display means to relocate, selectively, some or all of the sensor icons of the graphics artefacts at respective positions on or adjacent said representation, said positions corresponding to positions on, in or adjacent said body at which the radiation sensors represented by the selected sensor icons are to be positioned during subsequent irradiation of the body, and (iii) outputting to one or both of storage means and recording means a record of the displayed representation and graphics artefacts with the sensor icons in their relocated positions.

Abstract
In order to facilitate the display and evaluation of data acquired while irradiating a body, e.g. a patient undergoing radiation therapy, a dosimetry system has a plurality of sensors for disposition on, in or near the body to be irradiated and connected to a sensor reading instrument which is interfaced with a display system, for example a personal computer, which is arranged to display, in use, one or more representations, for example drawings or photographs, of the body to be irradiated, along with the positions and the dose data for those specific locations where the dosimeter sensors were placed.

10. A dosimetry system comprising:
-
(i) display means;
(ii) display control means for controlling the display means to provide, simultaneously, a display image comprising a representation of at least a portion of a body to be irradiated and a plurality of graphics artefacts each comprising a sensor icon representing a respective one of a plurality of radiation sensors to be positioned in, on or adjacent the body during subsequent irradiation of the body, and a corresponding identifier;
(iii) user-operable means for controlling the display control means to relocate, selectively, some or all of the sensor icons at respective positions on or adjacent said body image, said positions corresponding to positions on, in or adjacent said body at which the sensors themselves are to be positioned during subsequent irradiation of the body, and outputting to one or both of storage means and recording means a record of the displayed image showing the body image and graphics anefacts with the sensor portions positioned as relocated. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A storage medium carrying software for controlling a dosimetry apparatus to perform a method of determining locations of sensors in, on or adjacent a body prior to radiation by a radiation therapy system, the method comprising the steps of:
-
(i) displaying a display image comprising a representation of at least a portion of the body to be irradiated, and a plurality of graphics artefacts each representing a respective one of a plurality of radiation sensors to be positioned in, on or adjacent said body during subsequent irradiation of the body, each graphics artefact comprising a sensor icon and a sensor identifier;
(ii) adjusting the display image to relocate, selectively, some or all of the sensor icons at respective positions on or adjacent said representations, said positions corresponding to positions on, in or adjacent said body at which the actual radiation sensors are to be positioned during subsequent irradiation of the body, and (iii) recording the display image with the sensor icons positioned as relocated.
