Abstract
A kind of method for replacing lead point location using cotton balls when being positioned the present invention relates to CT scan, upper medical contrast medium is dipped in by the cotton pellet for being kneaded into medical absorbent cotton, and radiography cotton balls is made, patient body-surface is marked on to need to do the boundary of CT detection positions, instead of lead point, solve the problems, such as that lead point makes marks in body surface generation metal artifacts when CT scan positioning, contributes to doctor to the accurate judgement of conditions of patients and carries out accurate Rapid Dose Calculation.
Description
Technical field
The present invention relates to medical appurtenance technical fields, and in particular to replaces lead using cotton balls when a kind of CT scan positioning
The method of point location.
Background technology
Before radiation treatment, it will usually carry out CT scan positioning to patient and need suffering to determine the position for the treatment of
Person's body surface does lead point label.However, when using lead point, can occur significantly radial metal artifacts in CT film, due to
The presence of artifact seriously affects CT values, and the radiotherapy dosage being calculated according to CT values can occur inclined with actual conditions
Difference causes large effect to therapeutic effect.
Invention content
It is insufficient present in above-mentioned background technology it is an object of the invention to solve, it is replaced using cotton balls when CT scan is provided
The method of lead point location, using this method replace lead point, carry out CT scan when be not in artifact phenomenon.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of method for replacing lead point location using cotton balls when CT scan positioning, includes the following steps：
S1, a small amount of medical absorbent cotton is taken, and is kneaded into small cotton balls；
S2, the cotton balls is dipped in into upper medical contrast medium, kneaded, radiography cotton balls is made；
The radiography cotton balls m (m >=3) that S3, step of learning from else's experience S2 processing obtain is a, is marked on patient body-surface and needs to do CT inspections
Survey the boundary at position.
Medical contrast medium in the step S2 is in cardiografin, meglumine iotalamate, Iopromide, aliphatic acid iodide
One kind.
Preferably, the medical contrast medium in the step S2 is cardiografin.
M=3 in the step S3, that is, be marked on that patient body-surface needs to do CT detection positions boundary is moistened with Medical contrast
The radiography cotton balls of agent is 3, and 3 radiography cotton balls are in angular distribution in patient body-surface.
Radiography cotton balls in the step S3 is sticked to patient body-surface using adhesive tape.
The size of the radiography cotton balls is the same as lead point size.
This implementation new technique scheme has the following advantages that：
A. the present invention is added using cotton balls dips in radiography cotton balls made from contrast agent instead of lead point, and it is fixed to efficiently solve CT scan
Lead point makes marks when position leads to the problem of metal artifacts in body surface, contributes to doctor to the accurate judgement of conditions of patients and carries out accurate
True Rapid Dose Calculation.
B. the method for the present invention is simple, gathers materials on the spot, of low cost, has preferable promotional value.
Description of the drawings
It, below will be to needed in specific implementation mode in order to illustrate more clearly of the specific embodiment of the invention
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is some embodiments of the present invention, for this field
For those of ordinary skill, without creative efforts, other drawings may also be obtained based on these drawings.
Fig. 1 is the flow chart provided by the present invention that lead independent positioning method is replaced using cotton balls；
Fig. 2 is the CT scan figure that patient body-surface is marked on using lead point；
Fig. 3 is the CT scan figure that patient body-surface is marked on using the cotton balls of the invention for being moistened with contrast agent.
Specific implementation mode
Technical scheme of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiment of the present invention, ordinary skill people
The every other embodiment that member is obtained without making creative work, shall fall within the protection scope of the present invention.
A kind of method for replacing lead point location using cotton balls when CT scan positioning, which is characterized in that include the following steps：
S1, a small amount of medical absorbent cotton is taken, and is kneaded into the cotton balls of a diameter of 1-1.5mm；
S2, the cotton balls is fully immersed in contrast agent, takes out, gently kneads, have contrast agent exudation at this time, after
Continuous rubbing not squeeze firmly, and until cotton balls no longer sepage, shape is spherical shape, and radiography cotton balls is made；It needs to illustrate herein
It is to be moistened with the cotton balls of contrast agent to be only used for the positioning of CT detection positions, the shapes and sizes of cotton balls do not specially require, cotton
Ball can be circle, can also be boundary be irregular shape, be a substantially circular shape, ellipse, triangle is rectangular etc., all may be used
Realize goal of the invention；The amount of dipping of contrast agent, as long as label can be shown in angiographic procedure, it is demonstrated experimentally that
After cotton balls is completely soaked contrast agent, obtained radiography cotton balls is rubbed by hand, and apparent image can be presented when checking in CT, real
The goal of the invention of existing CT scan positioning.
The radiography cotton balls m (m >=3) that S3, step of learning from else's experience S2 processing obtain is a, and patient body-surface needs are sticked to using adhesive tape
Do the boundary of CT detection positions.The distribution mode of cotton balls is to be distributed along the boundary of CT detection positions, at least 3 distributed points.
Fig. 2 is the CT scan figure that patient body-surface is marked on using lead point, and there are more radial highly dense near lead point
Strip artifact is spent, Fig. 3 is the CT scan figure that patient body-surface is marked on using the cotton balls of the invention for being moistened with contrast agent.As can be seen that
The present invention is added using cotton balls dips in contrast agent instead of lead point, and lead point makes marks pseudo- in body surface generation metal when efficiently solving CT scan
The problem of shadow, contributes to doctor to the accurate judgement of conditions of patients and carries out accurate Rapid Dose Calculation.
One kind in cardiografin, meglumine iotalamate, Iopromide, aliphatic acid iodide may be selected in medical contrast medium, excellent
Select cardiografin.M is also at most unlimited in value in above-mentioned steps S3, it is contemplated that and actual use situation usually selects 3,
And 3 radiography cotton balls are in angular distribution in patient body-surface, the size of radiography cotton balls is the same as the CT examination size of lead point.
The method of the present invention is simple, gathers materials on the spot, of low cost, has preferable promotional value.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
Variation is still in the protection scope of this invention.
