Problems solved by technology

Here, the X-ray detection elements at both ends in the column direction may have poorer characteristics of the X-ray detection elements than the X-ray detection elements other than the X-ray detection elements at both ends in the column direction.
Similarly, the X-ray detection elements at both ends in the channel direction may have poorer characteristics of the X-ray detection elements than the X-ray detection elements other than the X-ray detection elements at both ends in the channel direction.

no. 1 approach

[0022] figure 1 It is a diagram showing an example of the configuration of the X-ray CT apparatus according to the first embodiment. Such as figure 1 As shown, the X-ray CT apparatus 1 according to the first embodiment includes a gantry device 10 , a bed device 30 , and a console device 40 .

[0023] here, in figure 1 In the diagram, the rotation axis of the rotation frame 13 in the non-tilted state or the longitudinal direction of the top plate 33 of the bed apparatus 30 is defined as the Z-axis direction. In addition, let the axial direction perpendicular to the Z-axis direction and horizontal to the bed surface be the X-axis direction. In addition, let the axial direction orthogonal to the Z-axis direction and the X-axis direction and perpendicular to the bed surface be the Y-axis direction. also, figure 1 It is a figure which draws the gantry device 10 from several directions for description, and shows the case where the X-ray CT apparatus 1 has one gantry device 10 ....

no. 2 approach

[0097] In the first embodiment, the case of using the X-ray detector module 12b as a dummy X-ray detector module was described, but the X-ray detector module 12b may not be used. Therefore, such an embodiment will be described as a second embodiment and a third embodiment. First, the second embodiment will be described, and then the third embodiment will be described. In addition, in the description of the second embodiment, the points different from the first embodiment will be mainly described, and the description of the same configuration as the first embodiment may be omitted.

[0098] Figure 5 It is a diagram showing an example of the configuration of the X-ray detector of the X-ray CT apparatus according to the second embodiment. The X-ray CT apparatus 2 according to the second embodiment differs from the X-ray CT apparatus 1 according to the first embodiment in that instead of the X-ray detector 12, it includes Figure 5 X-ray detector 72 is shown. Furthermore, the...

no. 3 approach

[0107] Next, a third embodiment will be described. In addition, in the description of the third embodiment, the points different from the first embodiment will be mainly described, and the description of the same configuration as the first embodiment may be omitted.

[0108] Figure 6 It is a diagram showing an example of the configuration of the X-ray detector of the X-ray CT apparatus according to the third embodiment. The X-ray CT apparatus 3 according to the third embodiment differs from the X-ray CT apparatus 1 according to the first embodiment in that instead of the X-ray detector 12, it includes Figure 6 X-ray detector 82 is shown. Furthermore, the X-ray detector 82 according to the third embodiment differs from the X-ray detector 12 according to the first embodiment in that it does not include the X-ray detector module 12b. Moreover, the X-ray detector 82 which concerns on 3rd Embodiment differs from the X-ray detector 12 in that it replaces with the two X-ray dete...

Abstract

An X-ray detector and an X-ray CT device. Provided are an X-ray detector and an X-ray CT device capable of suppressing deterioration in characteristics of X-ray detection elements at the ends of a plurality of X-ray detection elements that contribute to the generation of image data. The X-ray detector according to embodiments is an X-ray detector of a direct conversion type in which a plurality of X-ray detection elements are arranged in a column direction and a channel direction and voltage is applied between an anode and a cathode. The X-ray detector is provided with a controller. The controller performs control such that data from the X-ray detection elements at the end portions in the column direction or the channel direction of the X-ray detection elements is not used for generation of image data, and data from the X-ray detection elements other than the X-ray detection elements at the end portions in the column direction or the channel direction is used for generation of image data .

Description

[0001] References to related applications: [0002] This application enjoys the benefit of priority of Japanese Patent Application No. 2020-083646 filed on May 12, 2020, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments relate to an X-ray detector and an X-ray CT (Computed Tomography) apparatus. Background technique [0004] A photon counting detector includes a plurality of X-ray detection elements arranged two-dimensionally in the column direction (slice direction) and the channel direction. Here, the X-ray detection elements at both ends in the column direction may have poorer characteristics of the X-ray detection elements than the X-ray detection elements other than the X-ray detection elements at both ends in the column direction. Likewise, the X-ray detection elements at both ends in the channel direction may have poorer characteristics of the X-ray detection elements than the X-ray detection elements other than t...
