Detection of negative kidney calculus is difficult using X-ray imaging. This article shows that thermoacoustic imaging as a novel and complementary medical modality may become a fast and effective method for detecting negative kidney calculus.
Laser-based photoacoustic imaging and microwave-based thermoacoustic imaging could be the next successful generation imaging techniques in biomedical application. It can provide an effective approach of tissue structure and functional images to study the architectures, physiological and pathological properties and metabolisms of biological tissues.
Optical properties of porcine myocardium tissue in the exposure temperature range of 37-80degC were determined for 700, 750, 800, 850, 900 nm wavelengths of a Ti: sapphire laser. A neural network were trained with diffuse reflectance data from Monte Carlo simulations based on the semi-infinite tissue model, and then it was used to assess the absorption coefficient and reduced scattering coefficient...
