Publication number: 20200121282Abstract: Radiation treatment is delivered to a patient by positioning the patient such that a radiation beam is delivered to a lesion within the patient along a beam-delivery path while securing a diagnostic imaging device about the patient such that the diagnostic imaging device does not intersect the beam-delivery path. Radiation therapy is simultaneously delivered along the beam-delivery path while diagnostic images are obtained using the imaging device.Type: ApplicationFiled: December 13, 2019Publication date: April 23, 2020Inventors: Martin Lachaine, Sebastien Tremblay, Philippe Fortier, Sergei Koptenko, 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

Patent number: 9451928Abstract: A diagnostic image of internal anatomical features of a patient is annotated with representations of external features, such that both can be viewed together on a visual display. Adjustments to various treatment parameters relating to the administration of radiation therapy are provided, and the displayed image is automatically updated based on the adjustments.Type: GrantFiled: September 10, 2007Date of Patent: September 27, 2016Assignee: Elekta LTD.Inventors: Tony Falco, Martin Lachaine, Jason Gorman

Patent number: 9248316Abstract: 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: GrantFiled: September 22, 2011Date of Patent: February 2, 2016Assignee: ELEKTA LTD.Inventors: Martin Lachaine, Sebastien Tremblay, Fabienne Lathuiliere, Tony Falco

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

Patent number: 8366618Abstract: Methods and systems for assessing the effects of therapy on a patient include obtaining baseline and treatment ultrasound scans of a treatment area of a patient where the treatment ultrasound scans are taken subsequent to the baseline scan and at various times during a course of radiotherapy treatment sessions. The baseline and treatment ultrasounds are compared, and as a result a damage map representing cell death within the treatment area can be constructed.Type: GrantFiled: December 28, 2009Date of Patent: February 5, 2013Assignee: Elekta Ltd.Inventors: Tony Falco, Martin Lachaine

Patent number: 8249317Abstract: Portal images are combined with 3D ultrasound to determine adjustments to patient treatment parameters. The images are acquired while the patient is in an initial position, and the images are registered to a treatment coordinate system. The images are combined and outlines of anatomical structures are superimposed on the portal images, resulting in new portal images that incorporate the anatomy extracted from the ultrasound. The enhanced portal images are used to identify modifications to the treatment parameters.Type: GrantFiled: July 21, 2008Date of Patent: August 21, 2012Assignee: Eleckta Ltd.Inventors: Tony Falco, Martin Lachaine

Patent number: 8199981Abstract: Representations of a segmented, contoured organ or lesion are obtained from two-dimensional or three-dimensional images. A contour within the image of the lesion or organ of interest is used to identify a region around the initial contour and transform it into a boundary image comprising sampling lines that contain points identifying the organ boundary.Type: GrantFiled: May 18, 2007Date of Patent: June 12, 2012Assignee: Elekta Ltd.Inventors: Sergei Koptenko, Martin Lachaine, Xing Huang, Tony Falco

Patent number: 8189738Abstract: Radiation beam parameters are determined by manipulating a tool about a patient in order to determine a desired beam entry point and/or beam angle. In certain embodiments, a visual representation of the beam may be displayed along with images of internal and external anatomical features of the patient, and used to determine couch and/or gantry manipulation parameters to move the patient into a desired position with respect to a treatment delivery device.Type: GrantFiled: May 28, 2009Date of Patent: May 29, 2012Assignee: Elekta Ltd.Inventors: Chantal Dussault, Martin Lachaine, Daniel Lodu, Martin Bonneville

Patent number: 8135198Abstract: Techniques and systems for constructing a three-dimensional representations of anatomical structures from a series of images of the structure include creating interpolated images between actual images and defining voxels based on pixel values of the actual and interpolated images. A three-dimensional representation of the structure may be constructed based on the voxels.Type: GrantFiled: August 6, 2008Date of Patent: March 13, 2012Assignee: Resonant Medical, Inc.Inventors: Martin Lachaine, Ulrich Scheipers, Michael Donovan

Patent number: 8000442Abstract: Methods and apparatus for calibrating images and imaging devices to common coordinate systems utilize, in some embodiments, rods that detectably reflect an acoustic signal regardless of the incidence angle of the signal with respect to the rods. Typically, the rods are disposed within a “phantom” at known positions with respect to a room coordinate system. Images of the cylindrical rods may be obtained from different directions, allowing the imaging device to be calibrated to the room coordinate system.Type: GrantFiled: July 19, 2005Date of Patent: August 16, 2011Assignee: Resonant Medical, Inc.Inventors: Martin Lachaine, Tony Falco, Véronique Audet, Xing Huang
