Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.
[0027] Such as figure 1 As shown, the present invention provides a method for simulating the doctor's operation technique based on data mining and state learning, and its basic implementation process is as follows:
[0028] Step 1: Use the free-arm 3D ultrasound imaging system to record the normal vector N of each scanning point during the ultrasonic scanning process of the physician holding the ultrasonic probe on different tissue parts of the human body, and use the force sensor attached to the front end of the ultrasonic probe to record the normal vector N of each scanning point during the scanning process. The pressure value F of the contact surface between the ultrasonic probe and the human tissue at each scanning point, and the quality evaluation value of the currentl...

The invention provides a doctor operation technique simulation method based on data mining and state learning. Parameters such as pressure of the end, contacting with tissue skin, of an ultrasonic probe, ultrasonic image quality and an ultrasonic probe normal vector in an operation process serve as learning objects, and the law of doctor operation techniques is learned; clustering analysis is carried out on the operation techniques of a region of interest and a common region by adopting a fuzzy C-means clustering method, so that the complexity of the operation techniques is simplified; a Markov chain model is adopted to carry out state transition modeling on the dynamic change process of parameters corresponding to the operation techniques in an ultrasonic scanning process, and doctor scanning rules are described, so that the operation techniques of a professional doctor in the ultrasonic department can be effectively learned, automatic anthropomorphic ultrasonic scanning of a robot isconveniently realized, and a high-quality medical ultrasonic image is obtained.
Description
technical field [0001] The invention belongs to the technical field of data analysis, and in particular relates to a method for simulating a doctor's operation technique based on data mining and state learning. Background technique [0002] At present, although there are many methods of simulating the doctor's operation techniques applied to the ultrasonic scanning robot system, these methods can only be used for certain specific clinical applications. The operation process of the machine system lacks flexibility and intelligence, and a single operation is usually used. The method and fixed operation process, or the scan can only be completed after the operator teaches, and it is impossible to complete the scan similar to the doctor changing the scanning method according to the specific situation of the patient.
