Description

Radiotherapy positioning sticker with scale marks

[ technical field ] A method for producing a semiconductor device

The utility model relates to a take radiotherapy location sticker of scale mark is applied to the sticker of the straight line position of taking the scale mark and the coincidence of laser lamp that paste on fixed phantom when radiotherapy location.

[ background of the invention ]

Radiotherapy is one of three major means (surgery and chemotherapy) for treating malignant tumors, and about 70% of tumor patients need to receive radiotherapy with different degrees according to statistics. Modern precise radiotherapy mainly comprises a three-essence process of precise positioning, precise planning and precise treatment, wherein the precise positioning is an extremely important link in the three-essence process, and inaccurate positioning can cause great errors in subsequent radiotherapy planning and radiotherapy implementation processes and has important influence on the whole radiotherapy process. For patients receiving radiotherapy, in positioning, a white medical adhesive tape is adhered to the laser cross lines on the left side, the right side and the upper side of a fixed body model of the patients according to an external positioning laser lamp, then, a cross line positioning line is drawn on the medical adhesive tape along the laser line by a Mark pen manually, and an X-shaped seed-shaped metal Mark marking point is marked on the center point of the cross line to serve as a positioning Mark of a CT image. Due to the fact that the surface of the fixed body model is uneven (the thermoplastic body model is in a grid shape, and the negative pressure vacuum belt body model is in a curved surface), the adhesive tapes adhered to the fixed body model are uneven, the line of the cross word line positioning line drawn by external laser is not twisted, and therefore certain errors exist in the coincidence of the center point of the cross word line of the medical adhesive tape and the marked X-shaped kernel-shaped metal Mark point. The utility model provides a can be fast accurate mark out needs radiotherapy positioning mark line at radiotherapy position. The utility model provides a take sticker of scale mark, the printing has the scale mark in the middle of the front of sticker, and the scale mark is perpendicular with the intermediate line, and the scale increases in proper order from the outer lane to the inner circle, and the back is the non-setting adhesive, cuts respectively and gets two sections about 10cm location stickers, and the mark straight line of two stickers is successively pasted along laser line "ten" word line to the cross coincidence department mark metal point at the upper layer sticker.

[ Utility model ] content

The utility model provides a convenient operation, the scale is accurate, the clear radiotherapy location sticker of marking.

The utility model has the following specific technical scheme. The radiotherapy positioning sticker is strip-shaped, 2cm in width and 3m in length, a long middle line, a long scale mark and a short scale mark are printed in the middle of the front surface, the scales are sequentially increased from the outer ring to the inner ring and are vertical to the middle line, the scale precision is 1mm, 4 short scale mark lines separated by 1cm are provided with one long scale mark line, the length of each short scale mark line is the same as the width of the sticker, and the back surface of each short scale mark line is non-setting adhesive. As shown in figure 1, the front surface of the sticker is provided with a long middle line 2, a long scale line 4 and a short scale line 3. FIG. 2 is a plan view of two cut-out stickers A, B of about 10cm length, the sticker having a width of 2 cm. As shown in figure 3, the long middle lines of the two stickers A and B are coincided and stuck on the fixed phantom along the vertical direction and the horizontal direction of the cross of the laser line, wherein the long scale line 4 of the vertical sticker B on the upper layer is coincided with the long middle line 2 of the sticker A, and the cross center point 5 of the stickers A and B is marked with a metal Mark point.

Fig. 3 is a plan view of the combination of the stickers a and B of the present invention.

Wherein 1 is radiotherapy positioning paster with scale marks, 2 is long middle line of the paster, 3 is short scale line, 4 is long scale line, 5 is seed metal Mark Mark point.

[ detailed description ] embodiments

The invention will be further explained with reference to the drawings and the following embodiments.

As shown in figure 1, the front surface of the sticker is provided with long middle line scales 2, long scale lines 4 and short scale lines 3, the precision of the scale is 1mm, and the scales are sequentially increased from the outer ring to the inner ring. Two cut-off stickers A, B of about 10cm length are shown in FIG. 2, the sticker width being 2 cm.

Taking the grid-shaped thermoplastic fixed body model and the head support for brain tumor radiotherapy CT scanning and positioning as an example: if a head support is placed on a positioning CT bed, the head of a patient with brain tumor is rested on the head support, a latticed thermoplastic fixing body film is arranged around the front part and two sides of the head, the thermoplastic film is used for fixing the head of the patient after being cold-molded and formed in the shape of the head, a movable buckle is arranged between the thermoplastic film and the head support, the buckle is locked to limit the movement of the head, an external positioning laser lamp is turned on, the height of a CT machine tool and the proper bed entering depth are adjusted, and a cross laser indication line is projected to the fixing film of the head on the forehead and two temporal sides of the head. After the position of CT positioning is determined, radiotherapy positioning stickers A and B with scale marks, which are provided by the experiment and are used for pasting a 'cross' laser Mark of a forehead, a long middle line of the sticker A is pasted on a thermoplastic film along a transverse laser line of the 'cross' laser of the forehead, a long scale line 4 close to the laser 'cross' line is superposed with a vertical laser line, a long middle line 2 of the sticker B is pasted on the thermoplastic film along a vertical laser line of the 'cross' laser of the forehead, a long scale line 2 close to the laser 'cross' line is superposed with the transverse laser line, a 'cross' formed by the long scale lines 2 of the sticker A, B is superposed with the 'cross' of the forehead laser line, and a metal seed Mark point is marked at the superposed position. According to the pasting sequence and method of A and B, the operation is repeated for the cross mark lines of the laser on the two temporals of the head, then CT tomography is carried out on the positioning range, and finally the image data is transmitted to a treatment planning system to complete the positioning process.

The utility model has the advantages that: simple structure need not the manual setting-out on original medical adhesive tape, and the scale mark is clear, accurate, and the degree of accuracy of location further improves, still finds the start of sticker and accurately knows the surplus length of sticker in addition easily.
