Abstract

A brain tumor radiotherapy imitative positioning ruler is characterized by consisting of an AB ruler (1) with graduations, a CD ruler (2) with graduations, a nontransparent movable sliding block (3) and isocenter circles (4), wherein the AB ruler (1) with the graduations and the CD ruler (2) with the graduations are intersected vertically and are gathered with the isocenter circles (4), and are both 7cm away from the centers of the circle O of the isocenter circles (4) with a spacing being 2mm, and a spacing between adjacent isocenter circles (4) is 2mm. The brain tumor radiotherapy imitative positioning ruler is simple and practical in design, accurate in positioning, convenient to use, and simple and easy to learn, changes the original simple imitation method, is more accurate in positioning, and is more beneficial to and convenient for a doctor to diagnose diseases.

Description

Cerebroma radiotherapy simulation positioning rule

Technical field:

This utility model relates to a kind of novel cerebroma radiotherapy simulation positioning rule.

Background technology:

At present, the method for diagnosis and measurement to cerebroma radiotherapy commonly used is fairly simple in the hospital, accurately to the diagnosis of cerebroma size, just positions through simple ruler inadequately, is unfavorable for and is convenient to the diagnosis of doctor to the state of an illness.

The utility model content:

The purpose of this utility model provides a kind of novel cerebroma radiotherapy simulation positioning rule, when the cerebroma radiotherapy localization, on CT or MR image, measures tumor size and isocenter point; The simulation location that is particularly useful for the hemisphere tumor, simplicity of design, practicality, the location is accurately, and is easy to use, easy to learn, changed simple mimic way in the past, locatees more accurately, is more conducive to and is convenient to the diagnosis of doctor to the state of an illness.

In order to address the above problem; This utility model adopts following technical scheme; It by AB be with graduated scale (1), CD band graduated scale (2), opaque removable slide block (3) and etc. center circle (4) form; AB band graduated scale (1) intersect vertically with CD band graduated scale (2) and with etc. center circle (4) gather together, and distance be spaced apart 2mm etc. the distance of center circle (4) center of circle O be 7cm, each etc. be spaced apart 2mm between the center circle (4).

This utility model simplicity of design, practicality, the location accurately, and is easy to use, easy to learn, changed simple mimic way in the past, locatees more accurately, is more conducive to and is convenient to the diagnosis of doctor to the state of an illness.

Description of drawings:

Fig. 1 is the structural representation of this utility model.

The specific embodiment:

As shown in Figure 1; This specific embodiment by AB be with graduated scale (1), CD band graduated scale (2), opaque removable slide block (3) and etc. center circle (4) form; AB band graduated scale (1) intersect vertically with CD band graduated scale (2) and and etc. center circle (4) gather together; And apart from be spaced apart 2mm etc. the distance of center circle (4) center of circle O be 7cm, each etc. be spaced apart 2mm between the center circle (4).

When using in this specific embodiment, on sagittal plain tumor center tomographic image, center circle such as use tumor is wrapped up; AB, CD measure the size in length and breadth of O point range image frame perpendicular to framing mask, on the sagittal plain image of center, central point are measured then; The positioning of rotating chi, the slide plate upper limb placed saddle at the bottom of, the infraoccipital margin line, write down OD direction numerical value; On the OC direction, find out calvarium to central point distance; On the OB direction, find out occipital bone and central point distance, utilize this three numerical value, on analog machine, find out tumor center and get final product.The design of science on the whole makes product itself simple, practical, and the location accurately, and is easy to use, easy to learn, changed simple mimic way in the past, locatees more accurately, is more conducive to and is convenient to the diagnosis of doctor to the state of an illness.

Claims

1. positioning rule is simulated in cerebroma radiotherapy; It is characterized in that: it by AB be with graduated scale (1), CD band graduated scale (2), opaque removable slide block (3) and etc. center circle (4) form; AB band graduated scale (1) intersect vertically with CD band graduated scale (2) and with etc. center circle (4) gather together, and distance be spaced apart 2mm etc. the distance of center circle (4) center of circle O be 7cm.
