Publication number: 20230372739Abstract: Techniques are described to simulate partial patient images, such as 2D Megavolt (MV) images or 2D CT images, such as slices or projections, as the patient representation evolves during the radiation treatment, and then compare one or more actual patient images obtained during the radiation treatment to the one or more simulated partial patient images. A resulting image similarity indication, such as a pass/fail signal, can then be provided to a radiation therapy system to represent movement of the organ occurring during the radiation treatment.Type: ApplicationFiled: September 15, 2021Publication date: November 23, 2023Inventors: Martin Emile Lachaine, Tony Falco

Publication number: 20230302297Abstract: Techniques are described that use surface camera imaging data combined with other information to describe how a patient is moving in 4D. Intrabody imaging data, such as from CT images, and surface camera imaging data, such as from surface imaging cameras, can be acquired. A system can generate a model relating the intrabody imaging data having a three-dimensional (3D) patient representation to a two-dimensional (2D) surface patient representation. During a particular treatment fraction session, the system can obtain surface camera imaging data and use the surface camera imaging data and the model to calculate a 3D patient representation during the particular treatment fraction session. In this manner, surface camera imaging data can drive the model to provide motion management during (or before or after) a treatment session so that the 3D state of a patient is known at any given moment during (or before or after) a treatment session.Type: ApplicationFiled: August 17, 2021Publication date: September 28, 2023Inventors: Martin Emile Lachaine, Tony Falco

Publication number: 20230285776Abstract: A reference radiotherapy treatment plan having a plurality of control points, such as a sequence of gantry angles, aperture leaf positions, and intensity weights, can be adapted during the radiotherapy treatment session. Treatment imaging data of a patient may be obtained during the radiotherapy treatment session and one or more parameters may be determined using the treatment imaging data. Then, a current radiotherapy treatment plan may be generated based on the parameter(s).Type: ApplicationFiled: March 8, 2023Publication date: September 14, 2023Inventors: Martin Emile Lachaine, Tony Falco

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: 10531858Abstract: A method of presenting a suggested path for an ultrasound probe along a patient's surface includes obtaining a three-dimensional, non-ultrasound image of the patient and an ultrasound image of the patient. A treatment area is defined within the within the three-dimensional, non-ultrasound image, and using the images, defining a scanning site contour of an anatomical structure of interest within the patient and an external contour of the patient's surface. A preferred path of the ultrasound scan is projected onto the external contour such that an operator can reproduce the ultrasound scan without knowledge of the anatomical structure of interest.Type: GrantFiled: July 21, 2008Date of Patent: January 14, 2020Assignee: Elekta, LTDInventors: Martin Lachaine, Tony Falco
