Description
Technical field
This utility model belongs to medical instruments field, particularly a kind of radiotherapy laser lamp Installation And Calibration device.
Technical background
Radiotherapy is to utilize the biological effect of high-energy ray to come the kill tumor cell, reaches the purpose of control or healing tumour patient.It and operation, chemotherapy are the three big main means for the treatment of tumor at present, and adding up nearly tumour patient more than 70% according to World Health Organization (WHO) needs radiotherapy.Along with the radiation therapy technology development, Deng the common radiotherapy in center, three dimensional conformal radiation therapy, three-dimensional conformal intensity modulated radiation therapy and X-cutter technology are progressively carried out all over the world, and an important step of these technology is exactly to utilize three five laser beams that laser lamp sent to carry out patient's the solid location and the pendulum position of treatment, these five laser beams require to meet at a bit, and localization machine or accelerator etc. the center error be not more than 0.5mm.Its precision directly influences the precision of location and the treatment of pendulum position, therefore the adjustment of laser lamp is extremely important with calibration, the concrete installation requirement of three laser lamps is: a laser beam that sends " ten " font is respectively installed in the both sides of location bed or therapeutic bed, the parallel lines and the vertical line of two lamps overlap respectively, the intersection point of parallel lines and vertical line and machine etc. the center overlap.The 3rd laser lamp sends a vertical line and passes through the machine isocenter point.In order to reach above requirement, when the installation of laser lamp, the peaceful transposition that must focus on, rotate, tilt each the bar line that sends is whole, also there is not effective instrument utilization at present, available instrument is water pipe, plummet, prior pointer and blank sheet of paper etc., waste time and energy, and must two people cooperate adjustment.Therefore laser lamp is installed is become one of the installation personnel thing of headache the most.
Summary of the invention
The purpose of this utility model is to overcome the technical barrier of above existence, and a kind of simple and fast medical radiation laser lamp prover easily is provided.
The purpose of this utility model is achieved in that medical radiation laser lamp prover, the cuboid that main body is made up of six poly (methyl methacrylate) plates, wherein two glass plates are of a size of 40 * 30 * 1CM up and down, two jiaos and middle 3 * 3 * 1CM fixing heads of locating to be stained with 3 band M6 silk holes of opposite side of base plate; Japanning " ten " word line is carved with on the top board surface, and 10 * 10CM " ten " block field surface is coated white paint, and a top board left side, front side are provided with level indicator; The front and back two panels is of a size of 40 * 40 * 1CM, the front and back two panels has " fourth " font groove, all has the vertical slot of 30 * 0.15CM in the middle of the panel, and there is 30 * 0.15CM opening the top, the surface engraves every lattice 2MM's " well " font graduation mark, serves as zero outwards to increase with the both sides of groove; Left and right sides plate 3 is of a size of 30 * 40 * 1CM, and the center has the vertical slot 4 of 30 * 0.15CM, and the biside plate surface engraves two the parallel graduation marks identical with front and rear panel.By process six blocks of plates bonding after, must be parallel or vertical between each plate, the vertical slot centrage of every plate should overlap with " ten " word line of top board, and vertical in top board; Before and after the translot centrage of two plates should be parallel to two plates up and down, and be 1CM to the distance on top board surface; All around four plate surfaces all are coated with white paint except that the graduation mark zone, and purpose is the visuality that increases laser rays.The vertical slot centrage of four plates all overlaps with " ten " word line.
When using this utility model, will speed up the frame of device or analog machine, collimator, the bed angle places zero-bit, light open country " ten " word line, the light carpenters square all mixes up, and after earlier fixing the position of three laser lamps roughly according to conventional method, the installation calibrating instrument is put on the therapeutic bed, biside plate is positioned at frame and gets the G-T direction, level indicator on the contrast top board, regulate three bottom plate screws, it all around is up to the standard, turn on the wild lamp of light, light modulation open country to 30 * 40CM, adjust the prover position again light open country " ten " word line is overlapped with " ten " word line of prover, source-skin distance is adjusted to 99CM (source is 100CM to the distance of translot median plane), checks levelness again.
The adjustment of bed both sides laser lamp: the adjustment of (1) laser vertical line.Focusing mixes up the rotation that the back is transferred vertical line earlier, and it is just in time overlapped with the header board vertical slot.The deflection of the whole laser rays of second step makes its distance with the front and rear panel vertical slot equate (can see the scale indication).The translation of the whole laser rays of the 3rd step makes the laser vertical line pass the header board vertical slot, and just in time also passes back plate vertical slot.Can check widerly up and down by the lifting bed, vertical line adjustment so far finishes.(2) adjustment of horizontal laser light line.Same focusing mixes up the rotation that the back is transferred horizontal line earlier, and it is just in time overlapped with the header board translot.The deflection of the whole horizontal laser rays of second step makes its distance with the front and rear panel translot equate (can see the scale indication).The translation of the whole horizontal laser rays of the 3rd step makes the laser horizontal line pass the header board translot, and just in time also passes back plate translot, and horizontal line adjustment so far finishes.The method of adjustment of another " ten " word line laser lamp of bed offside is with last identical.
Bed is the adjustment of laser lamp (only sending vertical line) vertically.Focusing mixes up the rotation that the back is transferred vertical line earlier, and it is just in time overlapped with the side plate vertical slot.The deflection of the whole laser rays of second step makes its distance with the biside plate vertical slot equate (can see the scale indication).The translation of the whole laser rays of the 3rd step makes the laser vertical line pass the front side board vertical slot, and just in time also passes the back side panel vertical slot, and vertical line adjustment so far finishes.
The daily accuracy checking method of laser lamp is undertaken by above-mentioned installation adjusting method.
This utility model is reasonable in design, and installation calibrating is accurate, and is easy for operation.
