Accuracy.
【Description of the drawings】
Fig. 1 is the structural schematic diagram that rotary -60 radiosurgical treatment system of cobalt of the utility model gyro resets ruler；
Fig. 2 is that the structure for the module I that rotary -60 radiosurgical treatment system of cobalt of the utility model gyro resets ruler is shown
It is intended to；
Fig. 3 is that the structure for the module ii that rotary -60 radiosurgical treatment system of cobalt of the utility model gyro resets ruler is shown
It is intended to.
Wherein, 1.z values scale；2.x value scales；3. module I；4. module ii, 5. sliding blocks, 6. windows, 7. screws.
【Specific implementation mode】
The structural principle of the utility model and operation principle are described further below in conjunction with the accompanying drawings.
As shown in Figure 1-Figure 3, the extending direction of x values scale 2 is defined as the directions x, the extending direction definition of z values scale 1
For the directions z, the directions y are defined according to cartesian coordinate system.
Ruler is resetted to -60 radiosurgical treatment system of the rotary cobalt of the utility model gyro in 1 direction of z values scale to prolong
It is long so that its area coverage increases, and patient body-surface mark point selection region is more, is conducive to the fixation of patient body position.
For module I 3 and module ii 4, their length and width are all reduced, the distance between mark point is reduced, makes
The movement of module I 3 and module ii 4 is got up more smooth, it is more firm to fix.
The double track of x values scale 2 is changed to single track so that the movement of module ii 4 is more smoothly, more practical.
Increase by two module Is 3 and two module iis 4 so that the numerical value on the directions z is changed to 3 groups, every group by original 2 groups
All it is identical numerical value, the numerical value on the directions x is changed to 3 groups by 2 groups, and every group of two x values, each value is different, z values and x
It is worth the increase of numerical value, substantially increases the accuracy of Postural immobilization.
Rotary -60 radiosurgical treatment system of cobalt of the utility model gyro resets the use of ruler, including positioning using and
Treatment resets two steps.
Positioning uses：Ruler first is resetted to fix using rotary -60 radiosurgical treatment system of cobalt of gyro before patient's treatment
Position usually marks 4-6 mark point, each point to be corresponding with X values, Y value and Z values, these point values are carried out in patient body-surface
Record.Then CT scan is carried out to patient, CT images is input in planning system, carry out treatment plan design, every patient
Treatment is primary daily, probably treatment 8-10 times.
Treatment resets：It needs to reset ruler to patient with rotary -60 radiosurgical treatment system of cobalt of gyro before treatment every time
Position is resetted, consistent with position when CT scan before when to ensure treatment every time, including each mark point of verification
X values, Y value and Z values, will be consistent with what is recorded when CT scan, can just complete to treat every time, if inconsistent, need again
Carry out CT positioning.
Rotary -60 radiosurgical treatment system of cobalt of gyro of the utility model, which resets ruler, to read Z by module I 3
Value is read the X values of X scales by module ii 4, module I 3 and Y value can be read by crystal pen.
When being positioned using rotary -60 radiosurgical treatment system of the cobalt reset ruler of gyro, mark point is selected as possible
For the bone mark or skin agitation degree of patient and flat place.For the patient of special posture, in selected marker point,
Since body surface area is limited, module volume is bigger than normal, and distance increases between leading to mark point, and area also will increase, for such trouble
The each treatment repeatability of person will be affected, and influence the accuracy of patient's treatment.And the utility model gyro is rotary
- 60 radiosurgical treatment system of cobalt resets ruler, after the length and width of module I 3 and module ii 4 are all narrowed down to suitable dimension,
Reduce the distance between mark point so that the movement of module I 3 and module ii 4 is got up more smooth, and located space is big, and positioning is more smart
Standard, fixation is more firm, achievees the purpose that more accurately to treat.
Over the course for the treatment of, the reset before every tumor patient is treated, so the rotary cobalt -60 of gyro radiates
Surgical intervention system reset ruler is essential, and the reseting procedure of every patient is completed in treating computer room, because for the treatment of
Radioactive source is used in equipment, there is a small amount of scattered rays in computer room, and the medical staff that long campaigns are treated with work will do
To effective protection, the residence time in computer room just needs to shorten as possible.Due to the rotary cobalt of the gyro of the utility model -60
Radiosurgical treatment system resets ruler and improves the size of module I 3 and module ii 4 so that move it is more smoothly, and by x values
After scale 2 is changed to single track by double track, the Caton phenomenon of mobile module II4 will exclude.So, radiotherapy skill is just improved
The working efficiency of teacher reduces medical staff in the residence time of computer room, avoids medical staff by unnecessary x ray irradiation x.
