Publication number: 20240115882Abstract: Devices, systems and techniques are used for cancer treatment. An example control device may be configured to be communicatively coupled to a radiation source of a radiotherapy device and a position sensor of the radiotherapy device. The example control device may be used to calculate, for a sliding window of a radiotherapy treatment, a positional error between: a measured target position signal determined from a series of images and sampled at the acquisition times of the images, and an estimated target position signal. The example control device may generate a computer-executable instruction configured to alter the radiotherapy treatment in response to the positional error violating a threshold.Type: ApplicationFiled: April 28, 2023Publication date: April 11, 2024Inventors: Joshua Freedman, Fabienne Lathuiliere, Kevin John Brown, David Roberts, Sebastien Tremblay

Publication number: 20200023203Abstract: Various implementations of the invention provide techniques and supporting systems that facilitate real-time or near-real-time ultrasound tracking for the purpose of calculating changes in anatomical features during a medical procedure. More specifically, anatomical features within a patient undergoing a medical procedure are tracked by obtaining temporally-distinct three dimensional ultrasound images that include the feature of interest and obtaining a targeted subset of ultrasound images focused on the feature. Based on the targeted subset of ultrasound images, a displacement of the feature is determined and image parameters used to obtain the targeted subset of ultrasound images are adjusted based on the displacement. This results in a time-based sequence of three dimensional images and targeted ultrasound images of the feature that identify changes in the position, size, location, and/or shape of the feature.Type: ApplicationFiled: August 30, 2019Publication date: January 23, 2020Inventors: Martin Emile Lachaine, Sebastien Tremblay, Fabienne Lathuiliere, Tony Falco

Patent number: 10300305Abstract: An adaptive therapy delivery system can receive imaging information including a volumetric image comprising a target such as a tumor or one or more other structures, and can receive imaging information corresponding to one or more imaging slices comprising different portions of the target, such as imaging slices acquired at different times after acquisition of the volumetric image. The system can spatially register information from an earlier-acquired image with a portion of the target included in a later-acquired one of the imaging slices. The system can then determine an updated location of the target indicated by the spatially-registered information. Using the updated location, the system can generate an updated therapy protocol to control delivery of a therapy beam.Type: GrantFiled: April 19, 2018Date of Patent: May 28, 2019Assignee: Elekta, Inc.Inventors: Martin Emile Lachaine, Fabienne Lathuiliere, Michel Moreau

Patent number: 8929621Abstract: A contoured surface map of a lesion within a patient is obtained by shifting a reference surface to an estimated location in operational images. The process can be repeated to minimize errors, and the contoured surface map can then be segmented.Type: GrantFiled: December 20, 2005Date of Patent: January 6, 2015Assignee: Elekta, Ltd.Inventors: Fabienne Lathuilière, Véronique Audet, Tony Falco, Martin Lachaine
