Patent number: 10709419Abstract: A real-time imaging system that provides ultrasonic imaging and optoacoustic imaging coregistered through application of the same hand-held probe to generate and detect ultrasonic and optoacoustic signals. These signals are digitized, processed and used to reconstruct anatomical maps superimposed with maps of two functional parameters of blood hemoglobin index and blood oxygenation index. The blood hemoglobin index represents blood hemoglobin concentration changes in the areas of diagnostic interest relative to the background blood concentration. The blood oxygenation index represents blood oxygenation changes in the areas of diagnostic interest relative to the background level of blood oxygenation. These coregistered maps can be used to noninvasively differentiate malignant tumors from benign lumps and cysts.Type: GrantFiled: September 27, 2016Date of Patent: July 14, 2020Assignee: SENO MEDICAL INSTRUMENTS, INC.Inventors: Alexander A. Oraevsky, Sergey A. Ermilov, Andre Conjusteau, Peter Brecht, Vyacheslav Nadvoretskiy, Richard Su, Donald G. Herzog, Bryan Clingman, Jason Zalev

Patent number: 10433732Abstract: An optoacoustic imaging system includes a hand-held imaging probe having a light emitting portion and an array of ultrasonic transducers. The probe includes an acoustic lens having an optically reflective material that operates to avoid image artifacts associated with light interactions with the acoustic lens. The optically reflective material may be a thin, highly optically reflective metallic layer. The acoustic lens may be formed from a material such as silicone rubber filled with titanium dioxide or barium sulfate that allows it to reflect and scatter light from illumination components with substantially no absorption of such light, and yet be optically opaque. The probe may include a housing that provides hypo-echoic encapsulation of the probe. An assembly of the array of ultrasonic transducers may include a hypo-echoic material. The probe may include optical windows, each comprising one or more anti-reflection coated plates with acoustic impedance matching that of tissues to be imaged.Type: GrantFiled: January 22, 2013Date of Patent: October 8, 2019Assignee: SENO MEDICAL INSTRUMENTS, INC.Inventors: Alexander A.

Publication number: 20130190594Abstract: Provided herein are scanning, high-resolution optoacoustic imaging systems or microscopes. Generally, the system/microscope comprises subsystems for scanning a tissue or object therein with a wavelength of electromagnetic energy, such as optical energy, collecting and detecting ultrasonic waves produced when the tissue or object absorbs the incident wavelength and converting the same to an electrical signal, and for processing, analyzing and displaying the electrical signal as a digital image. Specifically, the system/microscope utilizes an off-axis parabolic reflector with a high numerical aperture value for deep tissue visualization. Also, provided is a method for collecting volumetric image data voxel-by-voxel within a subject utilizing the imaging system or microscope. A series of voxels within the scanned tissue produces detectable ultrasonic waves that are collected by the off-axis parabolic reflector and processed as described as a high-resolution image of the tissue or object therein.Type: ApplicationFiled: January 23, 2013Publication date: July 25, 2013Inventors: Alexander A.
