Vertebrae detection algorithm in CT scout images

In order to solve the tedious and time-consuming works for CT scan planning manually, we proposed an automatic detection method of vertebrae in CT scout images.In this method, firstly, HOG features of the training samples were computed, which were imported into the random forest classifier for training.Then we rotated the CT scout images seven times for detecting multiangle vertebrae.The trained classifier was employed to detect the.vertebrae in test images.Finally, we merged the detection resul
