Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, especially a kind of medical electron beam projection field outline drawing device.
Background technology
In the radiotherapy, the patient of nearly ten Percent five need adopt the high energy electron beam treatment.Adopt high energy electron beam treatment table shallow, partially during the pathological changes of position one side, have the outstanding advantages that high-energy X-ray can not reach.Single port exposure, target dose is even, and normal structure and organ dose are very little behind the target area, can effectively avoid the irradiation to deep tissue behind the target area.General electron beam calimator has gap about 5cm from skin surface.When this gap increased, field dose reduced, and the maximal dose point degree of depth deepens, dosage tonsure steepening, and x-ray pollutes to be increased, and high-power electron beam is changed significantly than low-energy electron beam.In the clinical practice, generally the standard irradiation open country of additional lead change calimator is irregular open country, with the shape of suitable target area, and the normal structure around the protection.
Prior art:
(1) in the ratio of linear accelerator radioactive source to the lower edge position of electron beam calimator, the image that CT is gathered passes on the planning system TPS, finishes delineating of launched field, obtains the launched field shape.Technique client need CT scan, and then make the plan in planning system, having increased patient's financial burden, CT scan causes certain injury to patient, and time-consuming.Particularly to the patient of journey pushing volume after some, if finish delineating of launched field in planning system, this expense exceeds several times than the electron beam therapy expense, and plan can not in time make out to affect patient's curative effect.
(2) place transparent plexiglass plate at linear accelerator calimator lower edge, allow patient be in the treatment position, the linear accelerator frame is rotated to the required angle for the treatment of, rise therapeutic bed and make calimator lower edge poly (methyl methacrylate) plate equal 5cm to the wild distance of patient exposure, finish delineating of launched field.The method has taken the expensive resource of linear accelerator, makes the accelerator inefficiency, complicated operation.
(3) directly take a poly (methyl methacrylate) plate to finish delineating of clinical treatment launched field at the wild 5cm of distance patient exposure place.The method is affected by human factors larger, admittedly the irradiation field shape of delineating out and actual launched field form error are large.
Summary of the invention
The purpose of this invention is to provide a kind of medical electron beam projection field outline drawing device.But its isolated operation operates simple and easyly, delineates accurately, and expense is low.
The technical solution used in the present invention:
Measure the linear accelerator radioactive source to the distance of calimator lower edge, namely the source range line is generally 95cm.The distance design obtains the application's boundling lamp to the distance of poly (methyl methacrylate) plate according to this.Guaranteed with linear accelerator to the consistent amplification of calimator lower edge.
Medical electron beam projection field outline drawing device of the present invention, delineating plate, boundling lamp and vehicle seat by y shaft holder, Y-axis slide mechanism, X-axis rotating mechanism, X-axis slide mechanism, target area forms, architectural feature is: fix a long frame shape Y-axis fixed mount of erectting in a side of vehicle seat, the fixed mount both sides comprise the Y-axis guide pillar, in the middle of going to the bottom, the Y-axis fixed mount is horizontally set with the Y-axis pivot link, described Y-axis slide mechanism comprises and is arranged on the Y-axis linear slide seat that can slide up and down of one on the Y-axis fixed mount, has the arc X-axis on the Y-axis linear slide seat and rotates chute; The X-axis rotating mechanism comprises two X-axis slip guide pillars, and an end of one bar is fixed on the Y-axis linear slide seat by rolling bearing, and another a end inserts X-axis and rotates in the chute, can be along camber line slip and fixing; The X-axis slide mechanism is included in to be fixed a transparent target area in the middle of two included X-axis slip guide pillars of described X-axis rotating mechanism and delineates plate; The target area delineates plate and boundling lamp distance is 95cm.
Y axle pivot link can 360 degree rotations.Be fixed with universal wheel under the vehicle seat.
Work process: patient is in the treatment position and fully exposes irradiation field, rotate chute at the x axle and regulate x axle rotation clamp screw to required treatment angle locking, then regulate y axle slip clamp screw to locking apart from irradiation field 5cm place at y spindle guide post, whether turn at last boundling lamp observation launched field is included in the poly (methyl methacrylate) plate scope, if do not have, can irradiation field be included in the poly (methyl methacrylate) plate at x axle slip guide pillar sliding guide sleeve or the mobile vehicle seat that universal wheel is housed, finish delineating of irradiation field shape.
Advantage of the present invention: with linear accelerator not in same therapeutic room, do not take the linear accelerator resource, reduced to a certain extent patient's medical expense, operate simple and easyly, relatively directly hold the machine glass plate with hands and delineate more accurate.
