In the related embodiments of fig. 1 to 4, a manner of rotating the object to be measured is described, for example, the object to be measured is seated on a seat, and the object to be measured is rotated by rotating the seat. However, it is also possible to provide the CT scanner in a rotating manner. In addition, both the CT scanner and the object to be measured may be rotated.

In the exemplary embodiment of fig. 5, an exemplary embodiment for rotating the CT scanner is provided. The embodiment of fig. 5 is different from the embodiment of fig. 1 in that the rotation device 400 rotates the CT photographing device around the measured object without rotating the measured object (e.g., a chair) (of course, the measured object may also be rotated), and for the same contents as those of the above embodiments, they will not be described again for the sake of brevity.

The source 210 and detector 220 may be oppositely disposed on the sides of the cantilever 410, with the cantilever 410 suspended from the top of the shielded space. As one example, the shape of the cantilever 410 may be substantially pi-shaped. The cantilever 410 can be driven to rotate the source 210 and detector 220 about the object under test. Furthermore, the cantilever 410 may be driven to rotate by a driving device, which may be a motor, for example, and may be mounted at or near the top, for example, by rotating a motor shaft to drive the cantilever 410, thereby rotating the source 210 and the detector 220 fixed to the cantilever 410, thereby realizing the rotation measurement.

Of course, it should be understood by those skilled in the art that other methods may be used as long as the relative rotation between the object to be measured and the CT photographing device can be achieved.

The traditional installation and use of CT equipment such as CBCT needs to configure and build a specialized ray protection machine room, the relevant national standards have strict standards and requirements on the construction and design of the machine room, the layout of the equipment in the machine room, the effective use area of the machine room, the dosage level outside a shielding body of the machine room, the reasonable arrangement of doors, windows and pipelines need to be considered, the process of building the machine room is long, the requirements on the construction and structural design are high, and the medical institution needs to spend high cost for installing and using the CT equipment. In addition, when a large number of small or old medical institutions such as clinics are upgraded and installed with CT devices, no usable or large-area site is available for building a new machine room, and the expansion of the treatment range and the technical upgrade of the medical institutions are limited to a certain extent. The modular or detachable CT equipment is not limited by a specific field, and the use limitation of the existing machine room is overcome, so that the convenient CT equipment and the convenient CT technology are provided for medical institutions, and the modular design and installation of the CT equipment are adopted, so that the CT equipment has the characteristics of convenience in installation, transportation and detachment.
