Introduction

The E.D.P. srl, certified ISO-9001/2000, is a company that since 1980 has worked in designing and manufacturing of electronic devices for scientific equipments and power conversion.

Strong experience from twenty-five years of presence in the international market, the EDP has produced a medical infrared camera - Thermo-Iewy, that allows a thermographic exam of the human body.

On the market are available a lot of different Infrared Camera. The fields of Application of this device are predictive maintenance, building diagnostic, process control, etc., that requires different spectral bands and sensibility.

The medical infrared camera Thermo-Iewy is specially intended for medical application.

"Medical Thermography" is a software kit, specially intended for medical infrared thermography application. The program works in Windows ME/2000/XP operating 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.

- 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.
.

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.

Typical speed of capturing of thermograms is 1 image per second.

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.

Group of build-in functions contains:

- Changing of palette (12 actual color and black-white palettes).

- Palette shifting for the best visualization of thermogram.

- Measuring of temperature difference (in °C or °F according to user's setting).

- Export of thermogram to standard BMP or JPG images for the purpose of further processing and using in another documents.

 - 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 position 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 axe is correspondent to the temperature in the each point of thermogram.

User can modify the palette, depth of image and brightness of thermogram.

 - Double Palette
This function allows you to change the palette in a particular area previous selected. I

n this way you can evidence the suspected area from the other.

Printing the patient's report with thermograms is easy and is performing on two steps: select the thermograms to be print out and press "Print" button after.

Printing is performing by the program according to special user's defined "Style", where many parameters are defined, such as: headers and fonts, size and position of thermograms on the page, possibility to print-out thermograms' headers, remarks etc.
