Purpose: InX‐ray fused with MRI, previously gathered roadmap MRI volume images are
overlaid on live X‐ray fluoroscopy images to help guide the clinician during an interventional …

Provided are methods and systems for registering image data from two imaging modalities,
to produce an image having features from both imaging technologies. In particular, the …

Purpose: The low dose rate brachytherapy procedure would benefit from an intraoperative
postimplant dosimetry verification technique to identify possible suboptimal dose coverage …

Relatively high radiation CT techniques are being widely used in diagnostic imaging raising
the concerns about cancer risk especially for routine screening of asymptomatic populations …

PURPOSE: To evaluate a prototypical system of dynamic intraoperative dosimetry for
prostate brachytherapy using registered ultrasound and fluoroscopy (RUF) with a …

We have developed a tomosynthesis-based radioactive seed localization method for
prostate brachytherapy. In contrast to the projection image-based matching approach, our …

Purpose: Accurate localization of prostate implants from several C‐arm images is necessary
for ultrasound‐fluoroscopy fusion and intraoperative dosimetry. The authors propose a …

A tomosynthesis-based prostate brachytherapy seed localization method is described.
Gaussian-blurred images are computed from a limited number of X-ray images, and a 3-D …

In prostate brachytherapy, a transrectal ultrasound (TRUS) will show the prostate boundary
but not all the implanted seeds, while fluoroscopy will show all the seeds clearly but not the …

PURPOSE: To assess the feasibility of using cone-beam tomosynthesis (CBTS) to localize
the air–tissue interface for the application of prostate image-guided radiation therapy using …
