X-ray film marking ring and bone X-ray film three-dimensional imaging method based on image recognition

Abstract

The invention belongs to the technical field of medical perspective imaging, and particularly relates to an X-ray film marking ring and a bone X-ray film three-dimensional imaging method based on image recognition. The X-ray film marking ring comprises a front half ring and a rear half ring which are made of plastic materials, one end of the front half ring is detachably connected with one end of the rear half ring, the other end of the front half ring is hinged to the other end of the rear half ring, the front half ring and the rear half ring are mutually spliced to form a circular ring shape, and a plurality of inserting grooves are circumferentially distributed in the end face of the front half ring and the end face of the rear half ring. The outer circle faces of the front half ring and the rear half ring are provided with scale marks, the inner circle faces of the front half ring and the rear half ring are provided with linings, the linings are made of elastic materials, marking plates are inserted into the inserting grooves, the marking plates are made of metal materials, and through hollowed-out marks are formed in the marking plates. According to the invention, the three-dimensional shape of the bone of the patient is generated through the two bone photos wearing the X-ray film marking rings at any angle, so that the shooting cost of the patient is reduced, and the shortage of medical resources is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical perspective imaging, and in particular relates to an X-ray film marker ring and a three-dimensional imaging method for bone X-ray film based on image recognition. Background technique [0002] In recent years, the development of medical imaging equipment has played a very significant role in promoting the progress of social medical level. Currently, common medical imaging devices include but are not limited to X-ray machines, computed tomography machines, magnetic resonance imaging machines, and the like. The filming prices, film quality, and film dimensions of the above equipment are all different. Among them, the price of X-ray film is the lowest, and the film is produced quickly, but the film is a two-dimensional image, and the film quality cannot be compared with CT and MRI. The X-ray film is processed to obtain the effect of a three-dimensional image similar to the human skeleton, which can...

Problems solved by technology

Usually in the actual shooting, the X-rays taken will cause a lot of overlapping coverage, and the clarity of different tissues is greatly different, such as bones are clearly visible, while some soft tissues are very blurred

[0004] In 2009, Herman used a standard reconstruction algorithm to reconstruct accurate CT images with hundreds of X-rays, but this technology requires too many X-ray angles and cannot be used clinically

There are also other researchers who construct the three-dimensional shape of bones through two X-rays taken at orthogonal angles, but in actual shooting, there are no truly orthogonal two X-rays, and the correspondence between the two X-rays The relationship is also not clear, so it can't really generate a three-dimensional figure that conforms to the actual condition of the patient's bone
