Embodiment Construction

[0030] Hereinafter, a PET-CT apparatus in which a PET apparatus as a nuclear medicine imaging apparatus and an X-ray CT apparatus are integrated will be described as an example of a radiation imaging apparatus.

[0031] figure 1 It is a diagram showing an overall image of the structure of the PET-CT apparatus in Example 1. exist figure 1 Among them, 100 denotes a PET-CT apparatus, 200 denotes a PET scanner, 300 denotes an X-ray CT scanner, 400 denotes a bed, 401 denotes a bed on which a subject is placed, and 402 denotes a subject. Such as figure 1 As shown, the PET-CT apparatus 100 has a PET scanner 200 , an X-ray CT scanner 300 , a bed 400 and a console apparatus 500 . figure 1 The x-direction indicates that the figure 1 The body axis direction of the subject 402 on the bed board 401 . The Y direction represents a direction on a horizontal plane perpendicular to the X direction. The Z direction represents a vertical direction.

[0032] The bed 400 has a bed board...

Abstract

The present invention relates to a radiation imaging apparatus, method and program. This radiation imaging apparatus can make the image quality of the region of interest better than that of other regions. A radiation imaging apparatus according to the present invention includes a storage unit, a morphology image capturing unit, an image acquisition unit, a position acquisition unit, a conversion unit, and a positional relationship adjustment unit. The morphological image imaging unit captures morphological images of the subject. The image acquisition unit acquires the form image from the storage unit. The position acquisition unit acquires the position corresponding to the region of interest within the acquired form image. The conversion unit converts the position in the acquired morphological image into the position in the captured morphological image. The positional relationship adjustment unit adjusts the positional relationship between the detector and the subject based on the conversion result.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from prior Japanese Patent Application No. 2010-128914 filed on June 4, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a radiation imaging apparatus, method and program. Background technique [0004] Conventionally, there are nuclear medicine imaging devices such as a gamma camera (Gamma camera), a SPECT (Single Photon Emission Computed Tomography) device, and a PET (Positron Emission Tomography: Positron Emission Tomography) device. Nuclear medicine imaging devices have detectors that detect radiation. In a nuclear medicine imaging device, the detector detects the radiation emitted from the isotope or labeling compound absorbed by the biological tissue and images the radiation dose distribution of the radiation detected by the detector to reconstruct the functional information of the...
