Virtual X-ray imaging method and virtual X-ray imaging system for human body bone joint

Abstract

The invention discloses a virtual X-ray imaging method and a virtual X-ray imaging system for a human body bone joint. The method comprises the steps that computed tomography (CT) is conducted on a targeted limb; the limb is converted into a data set formed by coordinates of a volume unit and an X-ray absorption rate; a course that a ray reaches an imaging plain through the limb is simulated by a numerical algorithm; visualization treatment is conducted on a numerical result; a gray level image that can be identified by a human eye is generated; and the result is outputted. For orthopedic and radio-diagnosis doctors, X-ray images generated by projection to the limb from any angles can be generated; the orthopedic and radio-diagnosis doctors can be assisted in learning X-ray anatomy, and establishing cognition connection between a three-dimensional structure and a two-dimensional image; for a radiographer, influences of different shooting parameters and a body position of an examined person on final imaging can be simulated; the method and the system contributes to learning a radiography technology of the radiographer; and for a special disease, the method and the system can assist in screening the optimal X-ray radiography body position and the angle for clinical reference.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a method and system for virtual X-ray imaging of human bone joints. Background technique [0002] X-ray film is an important method in the imaging diagnosis of bone and joint diseases. Although the development of medical imaging technologies such as computed tomography (CT) and magnetic resonance imaging (MRI) has provided new ways for orthopedic diagnosis, the information provided by traditional plain X-ray images is still irreplaceable. In addition, X-ray plain film imaging has the advantages of high image clarity, low radiation dose, low price, simple and fast, and can be examined under load, so it is still an indispensable means of clinical examination. [0003] X-ray plain film images are superimposed and projected on a two-dimensional plane in the perspective of the tissue structure in the direction of ray penetration. The images of different structures overlap each other, w...

Problems solved by technology

Observing and understanding these effects often requires repeated X-rays of the human body, which is not only costly, complicated to operate, and increases radiation intake, but also cannot be easily adjusted and observed in real time, making it difficult to implement in reality
