CORONARY ARTERY STENOSIS DETECTION BASED ON DEEP LEARNING MODELS
Nowadays, cardiovascular diseases are the most common threat to human health, and coronary artery disease is a particularly serious disease. Coronary angiography is used to detect coronary artery disease. However, the high cost and complexity of analyzing its results have led to the need to automate the process of diagnosis of coronary artery stenosis.
In this work, we considered popular models of deep learning-based stenosis detection. The models varied in their underlying neural network architecture and were pre-trained on publicly available data. The data consist of video sequences clinically obtained by invasive coronary angiography and labeled into separate frames for each video containing coronary artery stenosis with a resolution of (512x512) pixels. The paper presents a comparative analysis of the models based on the main performance indicators: average accuracy (mAP), image processing time, and the number of model parameters. The Faster R-CNN and EfficientDet D4 models showed the best performance. Compared to other models, they are characterized by relatively low parameter weights, high detection accuracy, and high image processing speed. The comparative analysis showed that the results of this study are superior to or comparable to those of other researchers.
