TL;DR: This work proposes a novel framework to address intraoperative dosimetry during prostate brachytherapy by reliable detection of a subset of seeds from 3D transrectal ultrasound and registration to fluoroscopy.

TL;DR: In this paper, a method of monitoring the cryoablation of a target volume of tissue with ultrasound elastography is proposed, which consists of acquiring a first elastograph image encompassing said target volume, performing at least one cycle of freezing and thawing of tissue encompassed in said target volumes, acquiring a second elastogram encompassing the same volume, and comparing the two images over the target volume.

TL;DR: A new approach for edge detection in ultrasound is proposed, which examines the image intensity profile for unit roots based on the Dickey–Fuller statistical test of stationarity, and a simple algorithm to build a segmentation method based on this approach is proposed.

TL;DR: It is shown that video examination of the autonomous camera view as it tracks the ring motion over the wire leads to more accurate user error detection than when using a fixed camera view, or camera movement with a fixed orientation.

TL;DR: Experimental results show that the implanted seeds can be successfully located in the reflected power images with high contrast and accuracy, and that the contour of the "prostate" can be detected in the ultrasound vibro-elastography images outside the shadow of the seeds.
