Quantitative Measurement of Polar-Molecule Perfusion for Tumor Detection by Thermoacoustic Doppler Ultrasound Dual-Modality Imaging

The authors propose a method for determining the supply of nutrient molecules in the body, and establish a dual-modality imaging system to realize this method. In their approach, thermoacoustic imaging reveals the density of nutrient molecules (which are not visible to conventional techniques), while Doppler ultrasound imaging shows the velocity of blood flow. Combining these results, one can obtain the nutritional perfusion velocity, and thus the nutritional supply level of living tissue, which can be an indicator for tumor detection.
