Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Using the Infrared Thermal Imaging to detecting Venous Thromboembolism | up to 24 months | ① Different levels of pseudocode (white, red, pink, yellow, green, blue, black) representing related IRTI that corresponds to a color scale bar of low to high temperatures, so we can know disease's position, extent and severity by comparing with the difference of color distribution and shape in the thermal imaging. ②The intensity of thermal distribution is higher than normals (great than or equal 0.5 Celsius degree is unnoraml), the symmetry of thermal range is relatively increased (pixels over 0.5 \ 1.0-fold), the difference of spatial distribution of the thermal field and the difference of statistically analyze are related to the disease. |
