A New Algorithm to Estimate Urine Volume from 3D Ultrasound Bladder Images

comparison of prostate and bladder volume measurements from mri and pre- and post-mri ultrasound images

background : safe dose escalation is highly desirable in radiotherapy for prostate cancer. prostate displacement due to bladder filling can be significant, so improved targeting of the prostate by ultrasound imaging potentially allows for a reduction in the target margin and consequently less toxicity. this study estimates the accuracy of ultrasound for prostate and bladder volume measurements ...

3D Cardiac Deformation from Ultrasound Images

The quantitative estimation of regional cardiac deformation from 3D image sequences has important clinical implications for the assessment of viability in the heart wall. Such estimates have so far been obtained almost exclusively from Magnetic Resonance (MR) images, specifically MR tagging. In this paper we describe a methodology for estimating cardiac deformations from 3D ultrasound images. T...

3d Reconstruction of Objects from Ultrasound Images

Developments in tools based on information technologies are assumed to have a fundamental impact on medicine. Computer assistance may be employed in surgical therapy for preoperative planning, intraoperative guidance and postoperative assessment (for example: in cranio-facial surgery, neurosurgery, orthopaedic surgery etc.). In this way, image and signal processing techniques abstract and inter...

Incremental Volume Rendereing Algorithm for Interactive 3d Ultrasound Imaging

This paper describes a medical 3D ulwasound imaging system that incrementally acquires and visualizes a 3D volume from a series of 2D images. The system acquires the image from a conventional B-mode 2D echography scanner, whose scanhead is attached to a mechanical tracking arm with three degrees of freedom. It reconstructs a stream of 2D images with their locations and orientations into a 3D ar...
