Abstract
The present invention discloses an external irradiation radio-field weight real-time regulation technique based on physiotherapy. Said technique includes the following steps: making every radio-field weight be visualized, on the basis real-time driving and regulating weight, at the same time real-time updating superposition dose after the weight is regulated so as to help doctor to quickly obtain a more satisfied therapeutic plane, so that it can raise working efficiency and can raise therapeutic effect.
Description
Technical field in the external radiotherapies such as radiation of tumor, usually with a plurality of light beam launched fields from different directions to the tumor exposure dose.Because lonizing radiation itself are exactly deleterious to human body; so it is first with treatment planning systems software simulation therapeutic scheme before the treatment of real enforcement roentgenization usually; under can the normal situation of due care when the killing tumor cells tissue is thought in evaluation; just determine treatment plan, and based on this implementing plan external radiotherapy.Wherein, owing to each beam irradiation time, problem difference, synergetic tumor absorbed dose result makes a world of difference.The doctor is formulating in the treatment plan by treatment planning systems software, usually will be after definite direction of illumination and irradiation field shape, make repeated attempts and adjust the weight of each launched field, simultaneously the damage of vitals and normal structure is controlled within the specific limits in the hope of reaching the lucky envelope tumor of high isodose to the tumor dose contribution.Because after each weight was adjusted, dosage needed important computations to upgrade, operate loaded down with trivial detailsly, thereby to take much time this link doctor and could obtain a treatment plan of comparatively being satisfied with.
Summary of the invention is to make the doctor can finish a good treatment plan quickly, adjust link in the launched field weight, the present invention adopts following visual real-time adjustment technology, make the doctor can be in real time, " What You See Is What You Get " carry out the weight adjustment, the variation of the Real Time Observation that is in course of adjustment simultaneously dose distribution and isodose, thereby can determine the optimal weight of each launched field fast, thereby can obtain the treatment plan of a satisfaction rapidly.
Description of drawings Fig. 1 is " the launched field weight is adjusted and the program evaluation sketch map in real time ".This figure is ultimate principle and the embodiment that the illustration meaning has illustrated this patent with the radiotherapy of pulmonary carcinoma.Wherein:
1. the weight adjustment of launched field 1;
2. the weight adjustment of launched field 2;
3. body surface;
4. the vitals that will protect in the radiotherapy (as left lung, spinal cord, right lung);
5. Zhi Liao focus target area;
6. focus target area therapeutic community indicatrix;
7. current launched field and weight are provided with the isodose that forms under the condition and distribute (having illustrated 3);
8. launched field 1;
9. launched field 2.
The specific embodiment illustrates the specific embodiment in conjunction with Fig. 1 here.At first determine launched field number and direction of illumination in the treatment plan by the doctor.Three launched fields have been determined in this example: launched field 1, launched field 2 and launched field 3.Software interface shows the direction of illumination and the current weight size of each launched field, and main display packing is to be that the center of circle is that each launched field shows a concentric circular with center, focus target area, wherein:
1, the weight size shows: the relative weighting that each radius of a circle size relative scale is expressed each launched field dosage contribution;
2, the launched field direction shows: the opposite direction of pressing the launched field irradiation goes up line segment of picture from the center of circle to each circle;
3, weight adjustment: when the user need adjust a certain beam weights, mouse is moved to launched field direction schematic lines and circular arc intersection point place and presses mouse, drag then; The weight circle that representative is adjusted the weight size amplified along with mouse drag or dwindled its radius along with mouse drag this moment, and the demonstration on display interface in real time of whole circle is also followed to amplify and dwindled;
4, dosage real-time update: in above-mentioned accent mouse drag was adjusted, dose distribution that shows on the current figure and isodose distributed and follow variation in real time, with the dose distribution as a result that may form under the real-time embodying current state;
5, the weight adjustment is determined: go up the convenience that function provides according to this, the doctor can lift mouse button to stop last time to drag adjustment when thinking that dose distribution is comparatively reasonable in dragging adjustment; And and then can continue to adjust the weight of other launched fields again.
This function adopts C Plus Plus can realize fully in conjunction with the graph and image processing technology on programming realizes, is not described in detail at this.
Claims (1)
1, a kind of software operation technology of adjusting the launched field weight in the therapy plot software system with physical principle external radiotherapy human diseases, the demonstration, adjustment and the dosage that comprise with weight show; Principal character is to show weight with visual graphics mode; User can be operated the adjustment of weight intuitively with mouse drag; When weight was adjusted, dose distribution, isodose curve or DVH assessment curve etc. can be followed variation in real time.
