Patent number: 11771325Abstract: A multispectral synchronized imaging system is provided. A multispectral light source of the system comprises: blue, green and red LEDs, and one or more non-visible light sources, each being independently addressable and configured to emit, in a sequence: at least visible white light, and non-visible light in one or more given non-visible frequency ranges. The system further comprises a camera and an optical filter arranged to filter light received at the camera, by: transmitting visible light from the LEDs; filter out non-visible light from the non-visible light sources; and otherwise transmit excited light emitted by a tissue sample excited by non-visible light. Images acquired by the camera are output to a display device. A control unit synchronizes acquisition of respective images at the camera for each of blue light, green light, visible white light, and excited light received at the camera, as reflected by the tissue sample.Type: GrantFiled: April 21, 2021Date of Patent: October 3, 2023Inventors: Ze Shan Yao, Piotr Kuchnio, Michael Frank Gunter Wood, Tammy Kee-Wai Lee, Yanhui Bai, Michael Peter Bulk, Christopher Thomas Jamieson

Patent number: 11506876Abstract: Methods and systems for controlling a surgical microscope. Moveable optics of the surgical microscope are controlled using two sets of control parameters, to reduce jitter and image instability. Shifts in the image due to changes in temperature or due to the use of optical filter can also be compensated. Misalignment between the mechanical axis and the optical axis of the surgical microscope can also be corrected.Type: GrantFiled: March 28, 2021Date of Patent: November 22, 2022Assignee: Synaptive Medical Inc.Inventors: Tammy Kee-Wai Lee, William La, Paul Quevedo, Aryeh Benjamin Taub, Yusuf Bismilla, Sam Anthony Leitch, Yuri Alexander Kuzyk, Ze Shan Yao, Michael Frank Gunter Wood
