Embodiment Construction

[0014] In accordance with the present principles, systems and methods are provided for automatic positioning of medical instruments, such as catheters or needles, in ultrasound (US) that take into account currently unattended, potentially occurring variables. According to a particularly useful embodiment, adaptive planning is employed for high dose rate (HDR) prostate brachytherapy. Since the radiative sources are sequentially introduced into the catheters, adjustments to the plan are possible before the sources are inserted into each catheter. Changes in prostate volume, prostate or catheter position, and other influences (movement, etc.) can be considered before or during tissue irradiation. This in turn can improve the consistency of dose coverage and increase the quality of treatment. An image-based registration method is employed to register the position of the catheter in an image coordinate system (eg, an ultrasound coordinate system).

Abstract

A system for dynamic localization of medical instruments includes an ultrasound imaging system (110) configured to image a volume where one or more medical instruments are deployed. A registration module (136) registers two images of the one or more medical instruments to compute a transform between the two images, the two images being separated in time. A planning module (142) is configured to have positions of the volume and the one or more medical instruments updated based on the transform and, in turn, update a treatment plan in accordance with the updated positions such that changes in the volume and positions of the one or more medical instruments are accounted for in the updated plan.

Description

technical field [0001] The present disclosure relates to medical instrumentation, and more particularly to systems and methods for adaptive planning and procedure updating using image-based techniques, such as for high dose rate (HDR) brachytherapy or other procedures. Background technique [0002] High dose rate (HDR) brachytherapy is a treatment for prostate cancer in which a radiation source is temporarily introduced into the prostate through several hollow catheters to kill the cancerous tissue. In ultrasound (US) guided HDR brachytherapy, a hollow catheter is implanted inside the prostate on a planned basis by passing it through a guiding grid. Then, three-dimensional (3D) US volumes were generated by translating the transrectal ultrasound (TRUS) probe from base to apex (apex). The prostate and catheter are segmented on the image, and the position of the catheter is sent to a computer, which determines where the radiation source is inside the catheter (dwell position) ...
