The user can select one of the first carrier 50a, the second carrier 50b, and the third carrier 50c to be connected to the carrier 40 according to actual application requirements for computer tomography. Figure 10 shows the correspondence between the light generator, the object and the detector in the computer tomography system of the preferred embodiment of the present invention. Since the first carrier 50a, the second carrier 50b, and the third carrier 50c have different operation requirements when performing computer tomography, there is a need for identification. In this embodiment, when the joint end 511 of the first bed 50a and the second end 412 of the rotating part 41 are detachably connected, the plurality of second conductive ends 531 of the second circuit board 53 are relatively against the first The plurality of first conducting terminals 423 of the circuit board 42 are electrically connected to generate a first identification signal.

Of course, this case is not limited to this. The first bed 50a The second bed 50b The third bed 50c SID (mm) 329.681 301.117 301.172 SOD (mm) 33.709 91.446 200.608 OID (mm) 295.972 209.671 100.564 Resolution pixel size (μm) 5 15 33 Table 1

The first bed 50a, the second bed 50b, and the third bed 50c use different first identification signals, second identification signals, and third identification signals to control the distance SID from the light generator 30 to the detector 60. The distance SOD from the light generator 30 to the object 9 and the distance OID from the object 9 to the detector 60 can generate different resolutions. However, it is not a necessary technical feature that restricts this case, and will not be repeated here. It is worth noting that, in the embodiment of the present case, when any one of the first carrier 50a, the second carrier 50b, and the third carrier 50c is detachably connected to the carrier 40, the The plurality of first lead terminals 423 of a circuit board 42 are arranged in concentric circles, and the axis of rotation of the carriage 50 also passes through the center of the concentric circle arrangement, corresponding to the plurality of second conductors arranged linearly on the second circuit board 53 The lead terminal 531, no matter the bed 50 rotates to any angle, after the bed 50 and the stage 40 are detachably connected, the plurality of first lead terminals 423 of the first circuit board 42 can be connected to the second circuit The plurality of second conductive terminals 531 of the board 53 form an effective electrical connection and generate an identification signal. Thereby, the controller 70 can recognize whether the first carrier 50a, the second carrier 50b or the third carrier 50c is connected to the carrier 40 according to the received identification signal. At the same time, the positions of the stage 40, the object 9, and the detector 60 relative to the light generator 30 are respectively adjusted according to the identification signal, and the rotation unit 21 is controlled to drive the carrying portion 51 of the bed 50 to rotate the carried object 9 through the rotating portion 41, The object 9 is irradiated with the light source of the light generator 30 for computer tomography.

When the carrier 50' is detachably connected to the carrier 40, the controller 70 can, for example, control the base 20 to drive the carrier 40 and the carrier 50' to move along the X-axis direction, and adjust the level of the object 9 along the Z-axis direction, for example. Height, while controlling the displacement of the detector 60 along the X-axis, so that the light source generator 30, the object 9 and the detector 60 are arranged in a linear arrangement for computer tomography, as shown in FIGS. 12A and 12B. In yet another embodiment, the carrier 50' can be detached from the carrier 40, and then connected to the carrier 40 by the carrier 50, as shown in FIGS. 2A and 2B. Since the computed tomography system 1 or the computed tomography system 1a can automatically identify the carrier 50 or the carrier 50', the user setting operation can be eliminated and the accuracy of the computed tomography can be ensured.
