Abstract
The invention relates to a positioning method and a device for radiotherapy. The movement of a radiotherapy bed is guided according to the position of a tumor in a laser three-dimensional image by introducing the tumor position in a CT three-dimensional image into the laser three-dimensional image. Because laser can perform scanning continuously all the time in the process of the radiotherapy, the continuous positioning in the therapy process is achieved, and the technical problem that an accidental movement of the body position of a patient cannot be corrected in real time by the prior positioning method and the device for radiotherapy in the therapy process is solved. Besides, because radioactive rays are not used, a human body cannot be injured.
Description
Technical field
The present invention relates to radiocurable localization method and device.
Prior art
In radiation therapy process, need accurately locate the patient's tumor position.The accurate positioning method that is usually used in patient at present has: electronics launched field device for image (EPID), digital X-ray machine, three-dimensional positioning framework or the like.The electronics launched field device for image (EPID) and the digital X-ray machine that are installed on the radiotherapy machine can be implemented accurate location, but cost an arm and a leg, patient will accept the roentgen radiation x of extra dose, when radiotherapy machine goes out to restraint, these image documentation equipments just need be closed, in therapeutic process, when the patient posture accident is mobile, just can't correct in real time.
Summary of the invention
The invention provides a kind of radiotherapy localization method, can't real-time corrigent technical problem to solve the shortcoming that has the radiotherapy localization method now and can not in therapeutic process, move to the patient posture accident.
The invention provides a kind of radiotherapy locating device simultaneously, to solve the shortcoming that has radiotherapy locating device now and can not in therapeutic process, move real-time corrigent technical problem to the patient posture accident.
In order to solve above technical problem, the technical scheme that the present invention takes is:
A kind of radiotherapy localization method is characterized in that, may further comprise the steps:
(1) on patient lies the CT bed, human body is comprised the CT scan of tumor and carries out computer CT 3D image reconstruction;
(2) patient lies on the radiation therapy bed, the Computerized three-dimensional image reconstruction is also carried out in the position of being scanned with CT in the laser scanning step (), the knub position that CT scan is obtained imports in the laser three-D image, obtain the position of tumor in the laser three-D image, instruct the radiation therapy bed motion according to the position of tumor in the laser three-D image.
Finish further comprising the steps of after the described step (two): in therapeutic process, continue to carry out step (two).
Described step (one) is also carried out following steps before carrying out: mount the telltale mark point at patient body body surface different parts, described step () comprises described telltale mark point when carrying out CT scan.
The knub position that in the described step (two) CT scan is obtained import in the laser three-D image method for the body surface profile diagram in the laser three-D image and CT scan acquisition body surface profile diagram registration overlap, tumor promptly appears on the relative position in the CT bed laser three-D body surface profile diagram.
When described step (two) continued to carry out, the knub position deviation that detects by each scanning instructed the radiation therapy bed motion.
A kind of radiotherapy locating device, comprise the CT machine, CT bed, radiotherapy machine, radiation therapy bed and computer, it is characterized in that, also comprise the radiation therapy bed laser instrument, described CT machine comprises the CT scan of tumor and carries out computer CT 3D image reconstruction human body, laser is carried out at the position that CT scanned with described radiation therapy bed laser instrument and the Computerized three-dimensional image reconstruction imports to the knub position that CT scan obtains in the laser three-D image, obtain the position of tumor in the laser three-D image, instruct the radiation therapy bed motion according to the position of tumor in the laser three-D image.
After having adopted technique scheme,, instruct the radiation therapy bed motion according to the position of tumor in the laser three-D image again because the knub position in the CT 3-D view is imported in the laser three-D image.Because laser can continue to scan in radiation therapy process all the time, thereby realize continuous positioning in the therapeutic process, having solved existing radiotherapy localization method and device can not be to the unexpected real-time corrigent technical problem that moves of patient posture in therapeutic process.In addition, owing to do not use lonizing radiation, therefore, can not damage human body.
