Description
Technical Field
The invention relates to medical auxiliary equipment, in particular to a film reading device for rapidly measuring the Cobb angle of an image film.
Background
Scoliosis is one of the common spinal deformities, frequently found in adolescents. Idiopathic Scoliosis (IS) IS the most common scoliosis, the etiology and pathogenesis are not clear, the pathogenesis IS hidden, the development stage IS high in progression risk, and partial children and teenagers have serious deformity when in diagnosis, and the serious influence IS caused on the aspects of the body, the mind and the like of patients. In recent years, the general incidence of the scoliosis of children and teenagers is in an ascending trend, the investigation and analysis of epidemiology characteristics of the scoliosis of 6-18 years old children and teenagers in a region A in the south shows that the positive rate is up to 5.33%, the spine screening of 176729 students in a region B shows that the detection rate of suspected scoliosis is 2.28%, and the investigation and research of the scoliosis occurrence condition of 35.82 children and 5-18 years old children in a plurality of regions in the west shows that the positive rate is 5.6%. Therefore, early discovery of early diagnostic early treatment is of great importance.
In view of the cost effectiveness of screening efforts and the radiation hazards, international institute of scoliosis orthopedic and rehabilitation (SOSORT) guidelines recommend that IS be diagnosed early by conducting a school scoliosis screening, that Adam anteversion tests be popular in all schools, and that Scoliometer be employed to aid in scoliosis screening. Although screening has been increasingly emphasized and standardized in recent years, the literature indicates that the rate of referral for screening positive patients is not high, and how to improve the referral rate and the local disease diagnostic capability is important. Screening, while finding abnormal signs associated with scoliosis, is not a method of diagnosing scoliosis.
The standing position full-spine positive side X-ray film is an imaging gold standard for diagnosing scoliosis. The EOS image system has the advantages of quick imaging, low radiation, no image splicing, capability of three-dimensional reconstruction, capability of obtaining rotation of vertebral bodies on axial positions, vertebral vector data and the like, and the measurement result also has higher accuracy and repeatability, is an ideal imaging method for current scoliosis evaluation, but the EOS three-dimensional reconstruction system is complex in operation, long in time consumption, high in cost, complex in imaging system, high in requirements on technicians and other limitations, so that the EOS three-dimensional reconstruction system cannot be widely applied to clinic, and particularly in remote areas, due to condition limitations, the use of an automatic spliced full-spine slice is more common. The traditional Cobb angle measurement method needs to draw a plurality of auxiliary lines in the process by determining the upper end vertebra and the lower end vertebra, making the tangent line of the vertebra body, making the vertical line and measuring the angle, has the advantages of complex measurement process, long time consumption, high requirement on a test site, large error and stained X-ray films, and therefore, the transfer diagnosis requirement of large-scale screening is difficult to meet.
Although some intelligent devices can realize rapid detection, large-area popularization cannot be realized in some areas with relatively backward economy due to the fact that the devices are expensive in price and the like.
