摘要：

The ultrasonic image of thyroid papillary carcinoma is characterized by two dimensional gray scale, low resolution, and complicated internal tissue structure. The characteristics of thyroid papillary carcinoma are not obvious and it is difficult to be distinguished. In this paper, the convolution neural network (CNN) theory is introduced for the automatic identification of the ultrasonic image of thyroid papillary carcinoma. Based on the improvement of the Faster RCNN, a detection method for the identification of ultrasonic image features of papillary thyroid carcinoma is proposed, that is, by connecting the fourth and fifth layers of the shared convolution layer in the Faster RCNN, and then normalizing. Secondly, multi-scale ultrasonic images are used in the input. Finally, thyroid papillary carcinoma is classified according to several major characteristics of its ultrasound image.so that the detailed ultrasound image diagnostic report can be received. The experimental results show that the recognition accuracy of the Faster RCNN is higher, the training time is shorter and the efficiency is higher compared with that of the original Faster RCNN. © 2017, Springer International Publishing AG.
