The primary aim of this work was to develop and study the potential of Capacitive Micro-machined Ultrasound Transducers (CMUTs) for dual-mode ultrasound therapy and imaging. This was investigated in the context of Ultrasound-guided High Intensity Focused Ultrasound (USgHIFU) designed for endocavitary HIFU tissue ablation of the prostate gland. The hypothesis is that this CMUT design could offer potential...
This preliminary study focuses on Capacitive Micro-machined Ultrasound Transducers (CMUTs) for dualmode ultrasound therapy and imaging. A planar probe design is being investigated in the context of Ultrasound-guided High Intensity Focused Ultrasound (USgHIFU) designed for endocavitary HIFU tissue ablation of the prostate gland. The hypothesis is that this CMUT design could offer potential advantages...
Here we report in-vivo validation of a fusion modeling method which associates real in-vivo motion data acquired from ultrasound speckle tracking imaging and data from a multi-scale modeling tool. This method aims at estimating the impact of in-vivo liver motion on High Intensity Focused Ultrasound (HIFU) treatments by quantifying thermal lesion deformations. A Dice Similarity Coefficient (DSC) was...
Atrial fibrillation (AF) is the most frequent cardiac arrhythmia. Left atrial catheter ablation is currently performed to treat this disease. Several energy sources are used, such as radio-frequency or cryotherapy. The main target of this procedure is to isolate the pulmonary veins. However, significant complications caused by the invasive procedure are described, such as stroke, tamponade, and atrioesophageal...
