Problems solved by technology

[0005] Suboptimal catheterization can result in bladder puncture, uneven catheter distribution with respect to the prostate, and catheter too close to the urethra, which can adversely affect dose coverage and / or increase exposure to normal tissue adjacent to the prostate and / or Radiation of structures (e.g., rectum) is therefore undesirable

Abstract

An interventional therapy system (100, 200, 300, 900) may include: at least one catheter configured for insertion into an object of interest (OOI); and at least one controller (102, 202, 910) that performs The following operations: obtain a reference image data set (540) comprising a plurality of image slices, the plurality of image slices forming a three-dimensional image of the OOI; define a restricted area (RA) in the reference image data set; at least one of a catheter intersection, a perimeter boundary of the OOI, and the RA defined in the reference data set to determine a location constraint for the at least one catheter; determine the location of the distal end of the at least one catheter and at least one of the orientations; and / or determining a planned trajectory for the at least one catheter based on the determined at least one position and orientation for the at least one catheter and the position constraints.

Description

technical field [0001] The present system relates to an interventional therapy system, and more particularly to an interventional therapy system for HDR brachytherapy with enhanced real-time tool guidance and real-time organ segmentation capabilities and a method of operation thereof. Background technique [0002] High dose rate (HDR) brachytherapy is a form of cancer treatment that utilizes high doses of ionizing radiation delivered over a short period of time (on the order of minutes) directly at or near a target. [0003] In HDR brachytherapy to the prostate, hollow catheters are inserted via a template through the patient's perineum and into the patient's prostate such that a segment of each catheter is located within the patient's prostate. Care must be taken not to penetrate the patient's bladder unnecessarily. Likewise, ensuring that the catheter is close to the borders of the prostate is an important clinical goal to reduce or minimize radiation dose to the central ...
