Bone tissue geometrical morphology parameter automatic measuring device and method based on image processing technology

Abstract

The invention provides a bone tissue geometrical morphology parameter automatic measuring device and a method based on the image processing technology. A bone tissue X-ray film is shot through a medical x-ray machine. The bone tissue X-ray film is subjected to pre-treatment, bone tissue segmentation and bone tissue parameter measurement by a computer, and a bone tissue parameter measurement result report is formed, transmitted and printed. A user only needs to select the name of a bone tissue and to-be-measured parameters before treatment, and segmentation and measurement processes are completely and automatically completed. Meanwhile, the initial contour selecting or labeling is not required for a doctor. The bone tissue geometrical morphology parameter automatic measuring device comprises an X-ray film data input interface unit, an image processing unit, a measurement parameter storage and output unit, a network interface unit and a printer interface. According to the invention, bone tissues in the X-ray film can be rapidly and automatically segmented and measured. By adopting the existing advanced GPU (graphics processing unit) and other hardware equipment, the bone tissues in the X-ray film can be automatically segmented and measure based on the image processing technology. Therefore, the film-reading automation level and the film-reading intelligence level of the doctor are improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent medical image diagnosis, in particular to the field of X-ray film automatic target analysis and recognition, bone tissue parameter measurement device and method, and in particular to an image processing technology-based automatic measurement device and method for bone tissue geometric morphological parameters . Background technique [0002] Musculoskeletal disorders (MSDs) are a major public health problem affecting 16% of adults and 30% of people over the age of 65 in the UK, and the total cost of arthritis treatment in the UK is estimated to exceed £30 billion a year . Relevant estimates indicate that the annual cost of MSDs in the United States is about 13-54 billion US dollars. Although my country lacks national data on the number and cost of MSDs, and MSDs has not yet been included in the list of statutory occupational diseases, epidemiological studies in different industries ha...

Problems solved by technology

[0005] As mentioned above, there is no fast and accurate method for bone tissue segmentation in X-ray films at present. The parameter measurement mainly depends on the doctor to mark the measurement, and it has not yet been automated.
