摘要： There is provided a calibration apparatus used for a photon counting type of radiation detector. In this apparatus, a radiation condition of a radiation is set such that particles of the radiation (X-rays) which are incident on a plurality of detection modules are piled up over each other at a probability which is equal to or less than a predetermined value. Under the setting of this radiation condition, detection sensitivities for the radiation are made uniform among the plurality of detection modules. Using this uniformed result, the detection sensitivities for the radiation are further made uniform every channel of each of the pixels formed by circuit groups including the plurality of detection modules, discrimination circuits and data calculation circuits and every discrimination circuit in each channel.

摘要： In the imaging space provided by a panoramic imaging apparatus, a phantom is arranged. The phantom is located to a predetermined tomographic plane and includes markers which image known positional information with an X-ray beam. The X-ray beam from an X-ray source is acquired as X-ray transmission data by a detector, and a panoramic image is produced using the data. Based on known positional information of the markers and information of marker positions in the panoramic image, distance information (Rs, Rd) between the X-ray tube and the detector and height information (B1) of the X-ray tube to the detector are calculated. From this calculated results and the acquired data, parameters (Δx/ΔFi, θ, Δθ/ΔFi, D, A, CX, CY) defining positional relationships among the X-ray tube, the detector, and the tomographic plane are calculated such that amounts of changes in the position connecting the X-ray tube and the detector are considered in the parameters. This allows the parameters to be calibrated for 3D image reconstruction.

摘要： An X-ray detector is provided with a plurality of modules each having a plurality of detection elements each composing a pixel, in which the detection elements convert incoming radiations to electric data depending on amounts of the radiations. The plural modules are mutually adjacently arranged on the same surface with a gap having a known width formed therebetween, such that the modules are arranged along at least one of a first X-axis and a first Y-axis, wherein the radiation detector is given a scan direction which is set along one of the first X- and Y-axes and the first Y-axis is perpendicular to the first X-axis. The plural detection elements of each module are two-dimensionally arranged along a second X-axis and a second Y-axis which are set obliquely to the first X-axis and the first Y-axis respectively and which are perpendicular to each other.
