Abstract
The utility model provides a practical medical infrared thermograph, which comprises an infrared lens, and is characterized in that: the infrared lens forms an image on a vanadium oxide uncooled detector; the vanadium oxide uncooled detector is connected with an acquisition system; the acquisition system is connected with a pretreatment system for calibrating and filtering heterogeneity; the pretreatment system is connected with an embedded system; the embedded system is communicated with a remote computer through a network; and the infrared lens is lifted through a noiseless remote wireless control hydraulic lifting system. The practical medical infrared thermograph, provided by the utility model, adopts the vanadium oxide uncooled detector, so that the temperature resolution is greatly improved; and simultaneously, the embedded system is introduced, so that multiple communication methods between the practical medical infrared thermograph and a remote computer are realized.
Description
Technical field
This utility model relates to a kind of practical medical infrared thermal imaging system, belongs to the medical infrared thermal imaging system technical field.
Background technology
Human body is a natural biological heater, because the difference of anatomical structure, tissue metabolism, blood circulation, function of nervous system's state, each position temperature of body is different, forms different thermal fields.Normal fuselage state has normal thermal map, and unusual fuselage state has unusual thermal map, and relatively both similarities and differences just can be diagnosed the nature and extent of inference disease in conjunction with clinical.Medical infrared thermal imaging system can convert the infrared light of human body radiation to the visual picture of reflection human body thermal field, and shows with pseudo-colours thermal map form, greatly makes things convenient for the doctor to diagnose.
Non-crystalline silicon (SI) detector of the France that existing non-refrigeration medical infrared thermal imaging system adopts, its temperature resolution is low, the losing of a lot of Useful Informations of the infrared chart that this can cause taking, thus influence the analysis and the diagnosis of disease.On the other hand, adopt the traditional USB interfacing, only suitable unit uses.Go up and down to adopt helical screw, noise is arranged.
Summary of the invention
The purpose of this utility model provides the practical more widely medical infrared thermal imaging system of a kind of raising temperature resolution and application scenario.
To achieve the above object, the present utility model provides a technical solution is practical medical uncooled infrared imaging, including infrared lens, wherein: Infrared imaging lens detector uncooled vanadium oxide, vanadium oxide Uncooled detectors connected acquisition system, acquisition system connected to non-uniformity correction and filtering pretreatment system, pretreatment system is connected embedded systems, embedded systems and remote computers to communicate over the network between the infrared lens lifting Bian wireless remote control with no noise hydraulic lifting system.
The practical medical infrared thermal imaging system of a kind of non-refrigeration that this utility model provides has adopted the non-cooled detector of vanadium oxide, has improved temperature resolution greatly, simultaneously, introduces embedded system, thus realized and remote computer between multiple communication mode.
Description of drawings
The circuit block diagram of a kind of non-refrigeration medical infrared thermal imaging system that Fig. 1 provides for this utility model.
The specific embodiment
For making this utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1; A kind of practical medical infrared thermal imaging system that this utility model provides comprises infrared lens, and infrared lens is imaged on the non-cooled detector of vanadium oxide; The non-cooled detector of vanadium oxide connects acquisition system; Acquisition system connects the pretreatment system to Nonuniformity Correction and filtering, and pretreatment system connects embedded system, communicates through network between embedded system and the remote computer.Lifting preclude the use of infrared camera noise wireless remote controlled hydraulic lifting system.
For making thermal imaging system have higher temperature control, infrared lens should have big as far as possible relative aperture and high transmitance.Optical focal length and bore are the major parameters of optical system, the detectivity of optics bore decision systems, and mainly emittance and the system according to the detection of a target confirms its operating distance, signal to noise ratio requirement.In the design of this instrument, select the camera lens of 17mm, F=1 for use.
The non-cooled detector of vanadium oxide of this use of the non-cooled detector of vanadium oxide U.S. FLIR, it is 324 * 256, pixel dimension 38 * 38um, response wave band 8-14um, temperature resolution is to arriving 40mk
Acquisition system adopts 14 A/D converters planar output conversion of signals of focusing to become digital signal, supplies with FPGA and computer and handles.
The Master Control Center of pretreatment system is FPGA, and this module is accomplished following function: Nonuniformity Correction, filtering
Embedded system is core with ARM, operation embedded Linux operating system, the driver through writing data acquisition and realize the network transmission of data and reception, parsing and the control of teleinstruction based on the multi-thread programming technology of TCP/IP.
Non-refrigeration medical infrared thermal imaging system, to the human body non-contact detecting, instrument itself does not send any radiation, and environmentally safe is noiseless, and is safe.This instrument has carried out strict performance test and environmental test, and its performance indications are reliable and stable.The main feature of this utility model is: 1, non-refrigeration imaging need not liquid nitrogen.2, focal plane scanning technique, the moment imaging, definition is good.3, high-temperature resolution.4, digitized image record, pseudo-colours shows, the abundant image processing capacity.5, receive only the infra-red radiation that target itself is sent, measured target is not had any infringement.6, contactless remote control thermometric does not change any parameter of measured target.7, dedicated analysis software, data base administration.8, the two control of operation dual fail-safe.
