Medical Thermography
version 1
General description
"Medical Thermography" is a software kit, specially intended for medical infrared thermography application. Program works in Windows'98/ME/2000/XP operation systems and was written in Delphi 5.0 language.
"Medical Thermography" operates with Thermo/IEWY medical infrared camera and provides all necessary functions, specific for medical purposes.
Main functions
The program is designed as a full-screen application. The user's interface is very easy in operation.
Main application's window is divided on two parts.
The left part of the screen contains the set of main program switchers (1), intended to change the mode of operation of the program. Below the main program switchers the control panel (2) is located. The contents of the control panel is changed in relation to the operation mode of the program.
Right part of the screen contains the operation panel (3). The contents of the operation panel is dependent on the operation mode of the program. At the top right corner of the screen two system buttons (4) are located.
Program is designed for multi-user operation (similar to Windows'XP operation system), where the current user is asked in loading of the program. Information about design, settings and working database is stored in the user's configuration and is loaded by program automatically.
Program uses original database format, where each patient's record is stored in separate file. Patient's record contains all necessary information about the patient (name, sex, age, text of final conclusion, remarks), as well as thermograms (up to 32000 in one patient's record).
Patient's record is displayed as a "case history" to provide more friendly interface for doctor. All information is displayed on 4 pages, there are: Identity, Thermograms, Thermogram table and Remark.
Database is indexed, so user can easy find required patient or collect a group of patients by their name, sex, age, keywords in conclusion, name of thermogram and markers.
Program allows easy create any number of new user's databases.
This version of software has a module constructed with real-time working with Thermo/IEWY infarred camera, connected with computer via USB 2.0 interface. Typical speed of capturing of thermograms is 1 image per 2 seconds.
In real-time operation mode with infrared camera is possible to improve the quality of received thermograms, using automatical adaptation of sensitivity and palette shifting. These functions allows to receive very color-stable thermograms.
Capturing utility has build-in automatic noise-reduction system, that allows receive very clear images.
Special intellectual sensitivity-adaptation system allows to improve the sensitivity of infrared camera for 4 times - from 0.08 °C hardware sensitivity up to 0.02 °C.
Post-processing of thermograms
Post-processing functions of thermograms are divided on two groups: build-in (frequently used functions) and external.
Group of build-in functions contains:
Group of external post-processing functions contains several functions, such as:
Geometry correction of thermogram
This function allows to modify geometric parameters of thermogram by X and Y axes independently and perform digital zooming of thermograms from -0.5 to +2 ratio. Also this function provides horizontal and vertical flipping of image. After all these modifications the thermogram is processed for reconstruction new binary 2D-matrix of thermogram.
Isotherm
This function allows to apply one or two independent isotherms on thermogram to define areas with equal temperatures. The thermal width, color and postion of each isotherm are defined and modified by user independently.
3D thermogram
Reconstruction of 3D thermogram is one of the most interesting functions of the "Medical Thermography" software kit. In this case X and Y axes of final 3D thermogram are corresponded to X and Y axes of the native 2D binary matrix, and the Z axes is correspondent to the temperature in the each point of thermogram. User can modify the palette, depth of image and brightness of thermogram.
All external post-processing functions are constructed as independent DLL-procedures, so it is very easy to get new functions and upgrade of software kit.
Print and print preview of the report
Program has ultimate real print preview function, where you can see the contents of future page. Printing of paient's report with thermograms became very easy now and is performing on two steps: select the thermograms to be print out and press "Print" button after.
Printing is performing by program according to special user's defined "Style", where a lot of parameters are defined, such as: headers and fonts, size and position of thermograms on the page, possibility to print-out thermograms' headers, remark etc.
This function allows to send for consultation selected patient's record (together with thermograms) for another doctor.
