Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of breath signal extracts and respiration movement guiding device.
Background technology
For being subjected to respiratory movement to influence bigger thorax and abdomen malignant, the key of implementing accurate radiotherapy is in simulation location and radiation therapy delivery process the target area to be detected and dynamic tracking in real time.The target area real time technique for tracking roughly is divided into based on the body internal labeling with based on body surface labelling two big classes.Often label is placed around lump inside or the lump based on the real time technique for tracking of body internal labeling, can utilize fixed relationship between label and the lump to infer the position of lump in real time, as the X line perspective imaging tumor real-time tracking system (RTRT system) of Hokkaido, Japan university research and development.The RTRT system shows implantation tumour inside or tumor goldc grains on every side in real time by X line penetrating image forming apparatus, detect the motion of target area, having obtained extensive use in pendulum bit correction, respiration gate control radiotherapy, real-time tracking radiotherapy, is the present the most frequently used target area apparatus for real time tracking based on the body internal labeling.But there is following point in the RTRT system: 1. the goldc grains implant procedure has necessarily traumaticly, has increased pneumothorax, hemorrhage, infection, the irritated equivalent risk of anaesthetic; 2. X line perspective causes extra X line to expose; 3. in the radiotherapy process, the part goldc grains is dislocated.When 4. implanting single goldc grains tumor being followed the tracks of, can not discern the distortion of tumor and rotatablely move, therefore, often need many goldc grains associatings.For this reason, people attempt passing through to extract the real-time tracking of the movable information realization of body surface to the target area.The real-time tracking system that is based on infrared photography (RPM system) of Varian Associates, Inc.'s research and development.The unit of plastic that has the infrared light reflection material is placed at patient's abdominal part or chest body surface by the RPM system, the infrared light diode of indoor certain position sends infrared light, the motion sensitive photographic head is caught on the unit of plastic catoptrical image and is passed to computer, obtain the movable information of body surface label by digitized processing, thereby realize real-time tracking the target area to image.Experiment showed, amplitude that the RPM system can effectively write down the body surface breath signal with the time mutually, therefore, in respiration gate control radiotherapy with follow the tracks of in the radiotherapy research and be used widely.Having operation based on the tracking technique of body surface labelling relatively simply, does not increase advantages such as extra X line exposure, has a good application prospect at aspects such as being used for four-dimensional CT scan, respiration gate control radiotherapy and real-time tracking radiotherapy.When application RPM system carried out real-time tracking to the target area, have two problems to need to consider: 1. can the motion of body surface label effectively predict the motion of in-vivo tumour.Studies show that, utilize the integrated signal prediction tumor motion of a plurality of skin-markers, be better than single labelled some tracking technique.Therefore, we propose to adopt multiple labeling point to replace single labelled point, and set up regression model, and the technology of utilizing the integrated signal of multiple labeling point that the position, target area is predicted is to improve the uncertainty of the single skin-marker tracking of knub of RPM system; 2. how to make the movement relation between body surface label and the in-vivo tumour keep constant in the radiotherapy process.Respiratory movement is a kind of half autonomic movement, when using the target area real time technique for tracking based on the body surface labelling, is necessary to set up simple, easy multiple breathing bootstrap technique.
At present, use more breathing guidance mode and comprise two kinds of audio-guided and video guiding, audio-guided audio prompt to patient's regular length " air-breathing ", " expiration ", the length of different breathing cycles is consistent, and the video guiding breathing that to be the patient draw oneself up by the respiratory waveform feedback of fixed amplitude is consistent the amplitude of different breathing cycles.In the clinical practice, the only application that has is audio-guided, more is to use the video guiding.Studies show that, compare with the above two, can obviously reduce the residual motion of tumor in conjunction with the guiding of video and audio frequency, most of patients can not cooperate complicated audiovisual respiratory movement guiding simultaneously, therefore, be necessary extracting mode and display mode, simplify and breathe guiding device that the breath signal of developing the easier cooperation of a kind of patient extracts and respiration movement guiding device by improving breath signal.
