Patent number: 11272984Abstract: Systems and methods are provided in which devices that are employed during a medical procedure are adaptively configured during the medical procedure, based on input or feedback that is associated with the current state, phase or context of the medical procedure. In some example embodiments, the input is obtained via the identification of one or more medical instruments present within a region of interest, and this input may be employed to determine configuration parameters for configuring the device. In other example embodiments, the input may be based on the image-based detection of a measure associated with the phase or context of the medical procedure, and this input may be employed to adaptively control the device based on the inferred context or phase of the medical procedure. In other embodiments, images from one imaging modality may be employed to adaptively switch to another imaging modality.Type: GrantFiled: July 7, 2017Date of Patent: March 15, 2022Assignee: SYNAPTIVE MEDICAL INC.Inventors: Cameron Piron, Michael Wood, Gal Sela, Joshua Richmond, Murugathas Yuwaraj, Stephen McFadyen, Alex Panther, Nishanthan Shanmugaratnam, William Lau, Monroe M.

Publication number: 20190388160Abstract: Systems, methods, and devices for intraoperatively confirming location of tissue structures during medical procedures. Preoperative image data of a patient's skeletal structure in a vicinity of an anatomical part undergoing a medical procedure is acquired. During the procedure, after exposing tissue intraoperative image data is acquired by scanning a selected region of tissue, in a vicinity of the skeletal structure using Polarization Sensitive-Optical Coherence Tomography (PS-OCT). Regions of tissue exhibiting structural organization in the vicinity of the skeletal structure are identified from the intraoperative (PS-OCT) image data. Geometrically correlating and registering the intraoperative (PS-OCT) image data with the preoperative image data of the skeletal structure in the vicinity of the anatomical part is then performed using a priori known anatomical information about the regions of tissue exhibiting structural information.Type: ApplicationFiled: July 19, 2019Publication date: December 26, 2019Inventors: Michael WOOD, Cameron PIRON, Murugathas YUWARAJ, Gal SELA, Joshua RICHMOND, Stephen MCFADYEN
