3D Thermal Volume Reconstruction from 2D Infrared Images—a Preliminary Study

Infrared imaging (IR) might be a useful diagnostic tool in case of abnormalities related to changes in body temperature. Most of the past methods were using IR images placed in a 2D space showing heat distribution on the analyzed object’s surface. The idea of the approach proposed in this study was to overcome that restriction and gain an internal distribution of heat. It was done by 3D backprojection reconstruction using a series of 2D infrared images of a heated phantom. The proposed system was validated using a registration procedure of thermal tomography and 3D ultrasound image of the analyzed object. Qualitative and quantitative assessment was held. The results suggest that areas of changing temperature in phantom could be detected and correspond to the actual placement of the heat source.
