Patent number: 11672491Abstract: Validation of a therapeutic radiation treatment involves using an applicator balloon surrounding an X-ray radiation source to support a plurality of X-ray sensor elements (XRSE). The XRSE are supported on the applicator balloon at distributed locations to sense applied radiation from the radiation source. At least one parameter of the applied radiation which has been sensed by the XRSE is compared to a corresponding parameter of a predetermined radiation treatment plan. Based on the comparing, a determination is made as to whether one or more requirements of the predetermined radiation treatment plan have been satisfied.Type: GrantFiled: October 7, 2019Date of Patent: June 13, 2023Assignee: EMPYREAN MEDICAL SYSTEMS, INC.Inventors: Kalman Fishman, Brian P.

Patent number: 10607802Abstract: Three dimensional beam forming X-ray source includes an electron beam generator (EBG) to generate an electron beam. A target element is disposed a predetermined distance from the EBG and positioned to intercept the electron beam. The target element is responsive to the electron beam to generate X-ray radiation. A beam former is disposed proximate to the target element and comprised of a material which interacts with the X-ray radiation to form an X-ray beam. An EBG control system controls at least one of a beam pattern and a direction of the X-ray beam by selectively varying a location where the electron beam intersects the target element to control an interaction of the X-ray radiation with the beam-former.Type: GrantFiled: March 30, 2018Date of Patent: March 31, 2020Assignee: SENSUS HEALTHCARE, INC.Inventors: Kalman Fishman, Brian P.

Patent number: 8755866Abstract: A system and method for optical lymph node mapping. The system is useful for guiding sentinel lymph node biopsy surgeries. A contrast agent that includes a fluorescent dye is injected near the site of a malignancy. The contrast agent drains into the lymphatic system, collecting in a sentinel node or nodes. The system utilizes one or more low-power continuous-wave lasers or light-emitting diodes modulated with a digital code sequence to probe the tissue suspected of containing the sentinel node. When the light is incident near the sentinel node, it will excite fluorescence from the dye. A portion of the scattered fluorescent light is captured with one or more photo-detectors. A correlation of the photo-detector signal and the digital code sequence is calculated to produce an estimate of the distribution of flight times for photons traveling from a given source to a given detector.Type: GrantFiled: May 3, 2006Date of Patent: June 17, 2014Assignee: Covidien LPInventors: John F. Heanue, Joseph A. Heanue, Brian P. Wilfley, Augustus P. Lowell

Patent number: 8545517Abstract: Tools and methods are provided for dissecting and/or removing biological units, such as hair follicles, from the body surface based on the images both above and below a body surface to reduce potential damage to the removed biological unit. The invention may be used in fully automated systems and also in a hand-held devices and systems. A system may produce a series of three-dimensional images of the body surface indicating follicular unit size, shape, position, and orientation both above and below the skin surface. The images may be utilized by an automated follicular unit harvesting tool, or maybe stored for later use. Imaging techniques include devices that sense light in the visible or infrared spectrums, optical coherence tomography, and ultrahigh frequency ultrasound.Type: GrantFiled: June 3, 2009Date of Patent: October 1, 2013Assignee: Restoration Robotics, Inc.Inventors: Mohan Bodduluri, Joseph A.
