Abstract
A location and swinging frame used for the tumour chemotherapy is composed of a left side plate, a right side plate, a front-end plate and a back-end plate. The upside of the front-end plate is arranged with a scale mark for the laser identification and the swinging of the Z coordinate. The left side plate is also arranged with the scale mark for the laser identification and the swinging of X and Y coordinates. The top of the location and swinging frame is fixed horizontally with three marker poles which are supplied for CT scanning and identification and being as location coordinates. Two marker poles are parallel and another marker pole is crossed with the other two. The left side of the location and swinging frame is arranged with two marker poles which are arranged for the CT scanning and identification and being as location coordinates. One marker pole is parallel to the top two marker poles and arranged in a different vertical plane. The utility model sets up CT imaging coordinates and confirms the center of the tumour by marker poles; and sets up laser swinging coordinates by the scale mark to place the center of the tumour in the center of a therapeutic machine, then the effect of the precise chemotherapy can be attained.
Description
One, technical field
This utility model relates to the tumour radiotherapy apparatus, is specifically to be used for the framework that the tumor radiotherapy process is correct, cervical region plays the location and the pendulum position acts on.
Two, background technology
In tumor accurate radiotherapy process, must patient's tumor be positioned, promptly generally by means of framework, utilize CT scan in CT shadow rubber chamber, determine tumor shape, profile and tumor center, and dosage is carved in the corresponding irradiation by transmitted intensity and irradiation time decision that accurately calculates a certain zone of concrete tumor.If the exposure dose deficiency then is not enough to kill cancer cell,, can injure normal cell tissue and organ again if exposure dose is excessive.After this, utilize therapy apparatus to carry out radiotherapy, and the precondition of implementing accurate radiotherapy is, must realize accurate repeated positioning in therapeutic room, be about to tumor center place exactly therapy apparatus etc. on the center, to carry out isocentric treatment.Existing positioning framework is separated with pendulum position framework, and the design of positioning framework does not consider to put the requirement of position.For accurate repeated positioning brings difficulty and obstacle.
Three, utility model content
The purpose of this utility model provides a kind of fixed pendulum position framework that is used for tumor radiotherapy that has location and repeated positioning effect concurrently.
This novel purpose is achieved in that a kind of fixed pendulum position framework that is used for tumor radiotherapy, mainly connect and compose framework by left and right side plate and forward and backward end plate, the front end-plate top of framework is provided with for laser identification, as the graduation mark of putting position Z coordinate, and left plate is provided with for laser identification, as the graduation mark of putting position X and Y coordinate; Frame roof flatly is fixed with for CT scan identification, as three marking rods of the elements of a fix, and wherein two marking rods are parallel to each other, and another marking rod is positioned on the crossing position of parallel marking rod with two; Also be provided with two marking rods that are intersection location for CT scan identification, as the elements of a fix, mutually on the frame left face, the one marking rod is parallel to two parallel marking rods of frame roof, and is positioned at different perpendiculars with it.
This device is for being attached to an external frame structure that has three-dimensional system of coordinate of patient.Wherein, three marking rods in horizontal plane of frame roof and two marking rods on the survey face of a framework left side are formed the CT coordinate systems in image: can adopt measure to determine that arbitrary amount is with respect to the locus of this coordinate system in the CT scan scope, thus, can obtain tumor center is the pinwheel coordinate; Secondly, by two graduation marks of the representative X on the left plate, Y coordinate and the graduation mark of the representative Z coordinate on the front end-plate, form the coordinate system of the accurate repeated positioning of laser.
During use, patient's incidence is fixed in this novel frame (frame fixation is on therapeutic bed), at CT Room, uses CT scan, determines the space coordinates of tumor center with respect to the CT coordinate systems in image; Again in therapeutic room, by therapeutic room's medial surface laser (be preferably both sides laser, the respective frame both sides all are provided with pendulum position coordinate scale line) and top lasers indication, carry out coordinate transform, with tumor center place therapy apparatus etc. the center, realize accurate repeated positioning, carried out isocentric treatment.Thereby two functions of this novel integrated location and pendulum position have been made condition for isocentric treatment, for accurate radiotherapy.
