摘要： A method and apparatus are provided for determining dose rate for one or more selected locations within an environment, the method comprising the steps of: a) measuring incident gamma ray energy and count rate for one or more locations within the environment to obtain a measured spectrum for those measured locations; b) measuring the spatial position of the measured locations; c) determining an emitted spectrum for the measured locations from the measured spectrum; d) inputting the emitted spectrum and measured location information to data processing means; and e) determining the dose rate at one or more selected locations from the calculated total gamma ray energy incident on those one or more selected locations arising from the emitted spectrum of the measured locations. In this way the invention provides an accurate solution for the dose rate at any point of interest within the environment based on the measured count and incident energies.

摘要： A system is disclosed for producing images representing radiation dose distribution in order to verify the radiation dose applied to a large area. The system uses a phantom assembly (10) constructed of material that is radiological equivalent to live tissue. The phantom assembly has slits (32, 34 and 36) where radiation sensitive film can be inserted and can include a channel for an insertable radiation generating device (20). The treatment dose is then applied to the phantom and the radiation sensitive film records the dose. A CCD camera microdensitometer is then used to read the exposed radiation sensitive film. The CCD camera microdensitometer includes a computer system which processes the image to remove artifacts and generates isodose contours for the radiation treatment applied. In addition, several pieces of radiation sensitive film in different planes can be exposed and processed in order to produce images representing the radiation dose distribution in three dimensions.

摘要： This invention is a phantom apparatus (10) for measuring the radiation dose distribution produced by a brachy-therapy device used to treat a localized area with radiation. The brachy-therapy device includes an insertable probe (24) capable of producing predefined radiation dose geometries about a predefined point. The phantom apparatus (10) includes a tank (12) containing a medium having a radiological equivalent characteristic of the localized area to be treated. The phantom apparatus (10) also includes a radiation sensor (32) for measuring the radiation dose and a positioning system for moving the probe (24) with respect to the radiation sensor (32). The radiation sensor (32) is also coupled to a positioning system (50) to orient the sensor (32) for optimal dose measurements. The phantom apparatus (10) includes a control system (160) that coordinates the movements of the probe (24) and the radiation sensor (32) to avoid a collision. The control system (160) moves the probe (24) along a predefined path around radiation sensor (32) and records the dose at predefined points along the path. In order to reduce the settling time of the sensor (32), the path is selected to coincide with the isodose contours of the radiation dose distribution of the probe (24).

摘要： A detection apparatus for detecting high energy radiation, preferably for detecting gamma radiation, coming from a source of high energy radiation in a detection volume, e.g. from one or more particles emitting high energy radiation. The apparatus comprises at least one detection surface configured to convert incident high energy radiation into a detection signal, and a collimator system comprising at least three collimator slits. Each collimator slit is arranged to project high energy radiation coming from a respective slit field of view of said detection volume onto said detection surface. At least two of said collimator slits extend in non-parallel directions and the respective slit fields of view of said at least two non-parallel collimator slits and the slit field of view of any other of said at least three collimator slits overlap and define a common detection volume of the detection apparatus.
