— This technology features a photon recycler to increase light transmittance through the human skull, a subtraction imaging method to image targets through human skull, and a filtering method to improve the contrast. Optical imaging is desirable because high functional hemoglobin contrast can be dire…
— In clinical practice, high imaging speed is critical to reduce motion artifacts, cost, and patient discomfort. Researchers at Washington University have developed multi-focal optical-resolution photoacoustic microscopy (MFOR-PAM) capable of high-resolution imaging of hemoglobin concentration and oxy…
— The greatest limitation on clinical use of existing photo-acoustic imaging technologies is the slow scanning speed caused by mechanical scanning, the bulky design of the scanning apparatus, and the necessity to immerse the body part into a ultrasonic coupling liquid. The present invention overcomes…
— A photoacoustic tomography device that provides high optical absorption contrast with high lateral resolution, including very good melanin distribution images, for port wine stain birthmarks.
