Dialog-type radiotherapy planning system based on voice recognition and dialog-type radiotherapy making method based on voice recognition

Abstract

The invention discloses a dialog-type radiotherapy planning system based on voice recognition and a dialog-type radiotherapy making method based on voice recognition. The dialog-type radiotherapy planning system based on speech recognition comprises a voice data acquisition module, an acoustic feature extraction module, a training acoustic model module, a training language model module, a decodermodule, and a radiotherapy command library comparison module, a command execution module, and a self-learning module. The language commands of a radiotherapy physician can quickly and efficiently control the operation execution of the radiotherapy planning system, and the radiotherapy planning system intelligently recognizes and understands the voice commands of the radiotherapy physician and converts voice signals into computer instructions that can be understood by the system. A dialog-type new interaction mode replaces the traditional mechanized human-machine interaction mode of the physician so as to improve the efficiency of the radiotherapy physician. Artificial intelligence and existing cases improve accuracy and improve radiotherapy effects.

Description

technical field [0001] The invention belongs to the application of computer technology in the field of medical physics, in particular to the field of radiotherapy, specifically a speech recognition-based conversational radiotherapy planning system, which can be used for radiologists to formulate radiotherapy plans in the process of treating tumor patients . Background technique [0002] Cancer is an important disease that threatens human health, and it is the number one cause of death in the world. In 2015, there were 4.292 million new cancer cases in China and 2.81 million deaths. About 70% of cancer patients need radiation therapy during the treatment of cancer, and about 40% of cancers can be cured with radiation therapy. At present, the proportion of cancer patients receiving radiation therapy in my country is far lower than that in developed countries, because of the limited resources of doctors and physicists. When a patient is diagnosed with cancer, doctors will foc...

AI Technical Summary

Problems solved by technology

The various operations of radiation therapists have their own repetitive and regular operations. The current technology does not effectively collect these operations, and a considerable amount of operation data has not been effectively used. This leads to radiation therapy physicists constantly doing a lot of repetitive, Low-efficiency work, spending a lot of time and energy on a single patient

Young radiation therapists need years of training in the early stage to be qualified to make radiation therapy plans. The long training period of radiation therapists has also led to a serious shortage of radiation therapists in my country. Quite a number of patients have not received enough patient and meticulous treatment, seriously Cancer of normal tissues can also occur due to incomplete treatment planning due to inexperienced radiation therapists
