Abstract
The invention relates to a method for measuring the internal temperature of objects through CT. The method includes the steps that a heat-sensitive material with a calibrated relation between density and temperature is manufactured into microcapsules and the microcapsules containing the heat-sensitive material are evenly mixed with the measured objects; the objects containing the microcapsules with the heat-sensitive material are scanned through CT in the processing process or after the processing process, so that the density change rate of the heat-sensitive material in the microcapsules in the objects is obtained; the calibrated density of the heat-sensitive material in the microcapsules is compared with the density of the heat-sensitive material in the microcapsules in the scanning process, so that the value of the temperature in the objects in the measuring process is obtained through conversion. According to the method for measuring the internal temperature of the objects through CT, the objects do not need to be punctured in the measuring process, the values of the temperature at multiple points inside the objects can be obtained, even a 3D temperature chart can be obtained, and the measured objects are not limited to the static state.
Description
Technical field
The present invention relates to a kind of temperature measurement technology, particularly a kind of method of utilizing CT to measure interior of articles temperature.
Background technology
Temperature survey is indispensable a kind of important means in current any industry and scientific research.By measuring the temperature of object, what we can be direct or indirect obtains other important information.Aspect medical science, we can judge a people's health condition by take temperature; In pharmacy procedure, high precision control temperature is to produce the important leverage of high-quality medicine; In space flight, be one of most important task of whole aerospace project within the specific limits the temperature control of spacecraft.Although unusual maturation of current thermometry, the technology such as such as thermopair, thermal resistance, infrared thermal imaging can accurately be measured the temperature of object, and they also have the limitation of self.For example, thermopair and thermal resistance must contact with testee in the time of thermometric, must insert object if need to measure interior of articles temperature, will destroy like this self structure of object.And infrared thermal imaging cannot obtain the temperature of interior of articles, because it can only perceive the infra-red intensity of body surface transmitting.Therefore the function that, current thermometry much cannot be realized in addition.For example, if the material being in sweat wriggling always or be stirred, just we cannot monitor inner heating situation; At researching human body, during to the digestive function of food, we also cannot obtain the quantity of heat production in stomach and enteron aisle.
Summary of the invention
The present invention be directed to the problem that the temperature of interior of articles cannot be monitored, a kind of method that CT of utilization measures interior of articles temperature has been proposed, that utilizes CT realizes the 3D stereoscanning to object temperature without insertion scanning function, can under the condition without getting involved, measure the three-dimensional Temperature Distribution of interior of articles.
Technical scheme of the present invention is: a kind of method of utilizing CT to measure interior of articles temperature, specifically comprises the steps:
1) thermo-sensitive material of demarcating the relation between density and temperature is made to microcapsules, then the microcapsules that are surrounded by thermo-sensitive material are evenly sneaked into testee;
2) CT scan is being processed or the object of the processed microcapsules that contain thermo-sensitive material, thereby obtains the rate of change of the density of thermo-sensitive material in interior of articles microcapsules;
3) density of thermo-sensitive material and the density of thermo-sensitive material in microcapsules while being scanned in the microcapsules of crossing by correlation calibration, converse the temperature value of tested moment interior of articles.
The interior thermo-sensitive material of described microcapsules occupies the ratio of the inner space of microcapsule shell and sets according to measuring temperature range.Indeformable in described microcapsule shell test process, ensure that the interior thermo-sensitive material of microcapsules occupies the ratio of the inner space of microcapsule shell.
The size of described microcapsule shell is greater than the minimum resolution of CT.
There is not chemical reaction in described microcapsule shell material and testee.
Beneficial effect of the present invention is: the present invention utilizes CT to measure the method for interior of articles temperature, in the time measuring without puncturing object; Can obtain the multiple temperature values of counting of interior of articles, or even 3D hygrogram; Testee is not limited to stationary state.
Embodiment
Whole course of work of the present invention and principle are as follows:
1, select thermo-sensitive material, and set up the relation between density and the temperature of thermo-sensitive material;
2, thermo-sensitive material is made to the inner non-microcapsules that are full of (full level depends on measurement range) completely, wherein, shell must use high strength and high chemically inert material to make, be that microcapsule shell need to have enough large Young modulus, with the opposing deformation that ambient pressure was brought, can not there is any chemical reaction with testee in microcapsule shell;
3, microcapsules are evenly sneaked in testee;
4, enter normal process or the processing procedure of material;
5, make CT scan the object that contains microcapsules according to pre-set programs, the size of microcapsule shell need to be greater than the minimum resolution of CT;
The variable density value of the thermo-sensitive material of the microcapsules inside 6, CT being obtained feeds back to the poster processing soft, and the relational expression obtaining according to step 1 is exported the temperature value of actual measured point.
