Verkhusha, Tuan Vo-Dinh, Yun Jing, Junjie Yao ABSTRACT In photoacoustic computed tomography (PACT) with short-pulsed laser excitation, wideband acoustic signals are generated in biological tissues with frequencies related to the effective shapes and sizes […]
Machine-Learning-Based Colorectal Tissue Classification via Acoustic Resolution Photoacoustic Microscopy
Author(s): Shangqing Tong, Peng Ge, Yanan Jiao, Zhaofu Ma, Ziye Li, Longhai Liu, Feng Gao, Xiaohui Du, Fei Gao ABSTRACT Colorectal cancer is a deadly disease that has become increasingly prevalent in recent years. Early detection is crucial for saving lives, but traditional diagnostic methods such as colonoscopy and biopsy have limitations. Colonoscopy cannot provide detailed information within the tissues affected by cancer, […]
Assessment of a Single-Element Scanning System for Enhanced Photoacoustic Imaging of Brain Hemorrhage
Author(s): Juliana Benavides Lara, Ravi Prakash, Kamran Avanaki ABSTRACT The use of photoacoustic brain imaging for hemorrhage detection holds significant clinical importance. This study focuses on the performance of sensitivity and detection capabilities of a single-element scanning system, considering the remarkable signal-to-noise ratio of photoacoustic signals generated by a single-element transducer. By employing blood vessel-like phantoms and […]
