Prostate Segmentation in HIFU Therapy

IEEE Transactions on Medical Imaging, 2011
Prostate segmentation in 3-D transrectal ultrasound images is an important step in the definition of the intra-operative planning of high intensity focused ultrasound (HIFU) therapy. This paper presents two main approaches for the semi-automatic methods based on discrete dynamic contour and optimal surface detection.

High-Frequency Jet Ventilation for HIFU [PDF]

CardioVascular and Interventional Radiology, 2014
We read the review by Muller et al. [1] about the management of respiratory motion in high-intensity focused ultrasound with great interest. As acknowledged by the authors, the motion of abdominal organs due to ventilation is sometimes a main obstacle for interventional radiology [2]. This is a critical issue for HIFU treatment where energy deposits in
