Technical Field

[0001] The present invention relates to the field of three-dimensional imaging technology, and in particular to image detection equipment, a detection system and a detection method thereof. Background Art

[0002] With the development of imaging technology, discovering and diagnosing diseases by observing medical images has become an important clinical diagnosis and treatment method. Taking CT imaging as an example, the human body is scanned by X-ray beams to obtain digital information of the human body structure, and then the reconstructed image obtained by computer processing has high resolution and accuracy because it is digital imaging rather than analog imaging.

[0003] The invention patent application with publication number CN110870775A discloses a system and method for imaging an object, wherein the X-ray source in the imaging system is arranged on a linear support structure. When the X-ray source is required to move along the support structure and emit X-rays toward the detector at the position of the subject, in order to ensure the imaging quality, the direction of the X-ray source relative to the detector needs to be adjusted significantly at any time, which seriously affects the continuity of the effective scanning process and thus the quality of the imaging. In addition, the X-ray source can only run along a single scanning path, which limits the expansion of applications.

[0004] Therefore, it is necessary to design a new type of image detection equipment to avoid the above problems existing in the prior art. Summary of the invention

[0029] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments.
