no. 1 Embodiment approach

[0030] figure 1 It is a configuration diagram showing an example of the configuration of the medical imaging diagnostic apparatus 1 according to the first embodiment. like figure 1 As shown, the medical image diagnostic apparatus 1 has a sick bed 10, a top plate 11, a moving part 12, a first scanning frame 13 (hereinafter referred to as a CT scanning frame 13), a second scanning frame 14 (hereinafter referred to as a PET scanning frame 14 ), projection data generation unit 15, reconstruction unit 16, storage unit 17, input unit 18, control unit 19, position determination unit 20, calculation unit 21, and display unit 22.

[0031] The hospital bed 10 supports a top plate 11 on which a model is placed so as to be movable about three orthogonal axes. The three orthogonal axes refer to axes defined by, for example, the short axis of the top plate 11, the long axis of the top plate 11, and an orthogonal axis perpendicular to the short axis and the long axis. Hereinafter, the dir...

no. 2 Embodiment approach

[0074] Next, details of the moving unit 12 of the medical imaging diagnostic apparatus 1 according to the second embodiment will be described. Figure 8 It is a configuration diagram showing an example of the configuration of the moving unit 12 in the medical imaging diagnostic apparatus 1 of the second embodiment. like image 3 As shown, the moving part 12 has a top plate driving part 123 , a scanning frame driving part 125 , a top plate moving mechanism 124 , and a scanning frame moving mechanism 126 .

[0075] The top drive unit 123 drives the top moving mechanism 124 . The gantry driving unit 125 drives the gantry moving mechanism 126 . The top drive unit 123 and the gantry drive unit 125 are drive devices such as motors, for example. The top drive unit 123 and the gantry drive unit 125 are driven according to control signals from the control unit 19 . The top board moving mechanism 124 moves the top board 11 by driving by the top board driving unit 123 . The gantry m...

no. 3 Embodiment approach

[0093] Next, a medical image diagnostic apparatus 1 according to a third embodiment will be described. In the first embodiment and the second embodiment, the method of adjusting the position of the top plate 11 in the calibration work of the nuclear medicine diagnostic apparatus using a phantom has been described. The first embodiment and the second embodiment can also be applied to imaging of a subject. In the third embodiment, the adjustment of the top plate position when imaging the subject will be described. The configuration of the medical image diagnostic apparatus 1 of the third embodiment is the same as that of the first embodiment. Hereinafter, differences from the first embodiment and the second embodiment will be described.

[0094] Figure 11 It is a flowchart showing an example of an imaging procedure of a subject using the medical imaging diagnostic apparatus 1 of the third embodiment.

Abstract

The predetermined position of the model placed on the top plate can be moved to the center position of the effective field of view of the nuclear medicine diagnostic apparatus. The top plate 11 places the subject. The hospital bed 10 supports a top plate 11 . The first gantry 13 has an X-ray generator and an X-ray detector that rotate around the top plate 11 . The second gantry 14 has a γ-ray detector for detecting γ-rays emitted from the subject. The moving part 12 relatively moves the top plate with respect to the second position based on the first position showing the center position of the effective field of view in the first gantry 13 and the second position showing the center position of the effective field of view in the second gantry 14 11.

Description

technical field [0001] Embodiments of the present invention relate to a medical image diagnosis apparatus, an X-ray CT apparatus, a nuclear medicine diagnosis apparatus, and a hospital bed apparatus. Background technique [0002] In recent years, with the advancement of medical technology, medical imaging diagnostic devices that combine X-ray CT (Computed Tomography, computerized tomography) devices and nuclear medicine diagnostic devices are rapidly spreading. PET (Positron Emission Tomography, Positron Emission Tomography) PET (Positron Emission Tomography, Positron Emission Tomography) PET-CT device, and X-ray CT device and SPECT device (Single-Photon Emission Computed Tomograph, Single-Photon Emission Computed Tomograph, single-photon emission computed tomography scanner) combined SPECT-CT device etc. In such a medical image diagnostic apparatus, a CT apparatus generates a morphological image reflecting the anatomical position of an imaging site. On the other hand, nuc...
