Automatic identifying and positioning system of pleura lines through ultrasonic, based on Radon transformation

Abstract

The invention discloses an automatic identifying and positioning system of pleura lines through ultrasonic, based on Radon transformation. The automatic identifying and positioning system is characterized by consisting of an ultrasonic image cropping module, a Radon transformation module, an image rotation module, a pleura line extracting module and a pleura line identifying and positioning module. Through a Radon transformation technique, peak points of pleura lines are extracted from cropped ultrasonic images, the range section of a pleura line transverse projection is obtained, and pleura lines are extracted, so that identifying and positioning of the pleura lines are realized. Compared with the prior art, the automatic identifying and positioning system disclosed by the invention has the advantages that the pleura lines can be quickly and accurately identified through combination of dissecting and dynamic characteristics of pleura, detection of the pleura lines can be more objective, quantitative evaluation of the pleura can be realized, diagnosis of some pleura diseases such as pleura inflammation and ultrasonic guided pleura puncture are facilitated, the confidence of inexperienced doctors for daily clinical diagnosis is increased, the efficiency of clinical operations is improved, and the automatic identifying and positioning system has great application prospects.

Description

technical field [0001] The invention relates to the technical field of medical ultrasonic automatic identification and measurement, in particular to an ultrasonic pleural line automatic identification and positioning system based on Radon transformation. Background technique [0002] The pleura often appears as bright lines in ultrasound scans. As a key anatomical landmark, the pleural line plays an important role in lung ultrasound. It is not only the interface between the chest wall and the lungs, but also related to many lung diseases, such as Pleural thickening and pleural effusion. Assessment of the pleural line is applicable in a variety of medical settings, including emergency medicine, respiratory care, surgery, interventional radiology, critical care, and anesthesia, among others. In addition, pleural line detection is the basis for evaluating multiple sonographic features of the lungs, including lung sliding, lung pulses, pleural thickening, and abnormal pleural l...

AI Technical Summary

Problems solved by technology

[0003] The detection and evaluation of the pleural line in the prior art mainly relies on traditional visual ultrasonography, but there are certain limitations. The existing problems are: first, the pleural line is easily mistakenly identified as the interface between the chest muscle and the fat layer; Second, the pleural line may exhibit an irregular shape in a pathological state, making it difficult to examine and evaluate; third, quantitative assessment of the pleura is difficult, especially when the pleura is not clearly displayed in a pathological state to measure pleural thickness
