Embodiment approach

[0062] First, as an embodiment, refer to Figure 1 to Figure 15 An embodiment of a data processing device and a data processing method for X-ray inspection according to an aspect of the present invention will be described. figure 1 The schematic structure of the X-ray inspection system (X-ray inspection apparatus) 10 is shown. In this embodiment, the data processing device and the data processing method are focused on the description, so the known parts of the X-ray inspection system 10 will be briefly described.

[0063] A data processing device 12 is communicably connected to the X-ray inspection system 10 via a communication line LN. The data processing device 12 may be integrated with, for example, a control unit of the X-ray inspection system 10, or may be provided separately.

[0064] The X-ray inspection system 10 is used, for example, as an X-ray-based non-destructive inspection system or a medical X-ray panoramic imaging system. As inspection objects of the X-ray inspectio...

[0199] In addition, the calculation formula (8) used to create the above-mentioned absorption vector long image may be generalized into the following form.

[0200] (a×(μ 1 t) 2 +b×(μ 2 t) 2 +c×(μ 3 t) 2 ) 1 / 2 ……(8')

[0201] Here, a, b, and c are coefficients of arbitrary values ​​used for weighting calculation. The absorption vector length image created according to this calculation formula can be used to design the irradiation conditions of the X-ray tube, etc. By designing the irradiation conditions, the X-ray tube can be irradiated with X-rays having an incident energy spectrum corresponding to the type and specific gravity of the substance to be inspected, for example.

[0203] In addition, as another modification, Figure 16 The X-ray inspection apparatus according to the present invention is shown as an example of a medical rheumatism inspection apparatus. Such as Figure 16 As shown, the rheumatism inspection apparatus 118 is provided with a scanned image moving mechanism 120 that uses the joints of the subject’s hand as the inspection object OB, and separates the X-ray generator 121 from the photon counting detection unit 126 Facing the joint, and the pair of X-ray generators 121 and the photon counting detection unit 126 Figure 16 Move in the front and back direction of the paper. The rheumatism inspection device 118 further includes: a reconstruction unit 111 that processes the frame data output from the detection unit 126; a data processing device 112 that receives reconstruction information from the reconstruction unit 111 and performs the above-mentioned substance determination processing; and a display monitor 138. Display the proces...

Abstract

The present invention can determine the type and shape of a substance with higher accuracy regardless of the thickness. The data processing device (12) counts the X-rays transmitted through the object after being irradiated from the X-ray tube (21) and detected by the photon counting type detection unit (26), in units of pixels in each energy region to process. The device (12) includes: means (35) for calculating an image of an object (OB) based on the count value; and means (35) for setting a region of interest on the image. Further, the device (12) has: a unit (35) for removing pixel information existing in the region of interest as a material background from the image; The count value of the unit, and the specific transmission characteristic of the substance with respect to the X-ray is calculated in the unit of the pixel as the unit of the unique information (35).

Description

Technical field [0001] The present invention relates to a data processing device, a data processing method, and an X-ray inspection device equipped with the device, which processes X-ray transmission data collected by X-ray scanning an inspection object. In particular, the present invention relates to a data processing device, a data processing method, and an X-ray inspection device having the function of determining (specifying or presuming) the area of ​​interest of inspection objects such as food, industrial products, and a part of the human body based on X-ray transmission data At least the type or property of the object, or detect whether there is a substance that may be located on the inner or outer surface of the inspection object and have a different composition from the object, or determine (specify or presume) the type or property of the object or substance. Background technique [0002] In recent years, there is a need to use X-rays to specify the type and shape of obj...
