  • Patent number: 10888304
    Abstract: Methods and system for producing combined photoacoustic/ultrasonic image frames use a low-power narrow beam laser to direct sequential pulses along a path overlying an internal region of interest. Photoacoustic responses are received and used to generate sub-frames. Between each of the laser pulses a plurality of ultrasound pulse-echo beams are sequentially emitted towards the region of interest, and the reflections are received and used to generate ultrasound sub-frames. The photoacoustic sub-frames are combined to produce a photoacoustic frame, and the ultrasound sub-frames are combined to produce an ultrasound frame. The photoacoustic and ultrasound frames are combined to produce an image frame. The method and system are suitable for producing real-time, high-contrast video.

  • Patent number: 10835204
    Abstract: A system and method for tracking completeness of co-registered medical image data is disclosed herein. The system and method tracks the position of an anatomical reference marker positionable on a patient and an ultrasound probe during an imaging session and co-registers medical images based on positional data received from the anatomical reference marker and the ultrasound probe. Using the co-registered image data, the system and method generates a surface contour of a region of interest (ROI) of the patient, such as a breast. The surface contour is defined to represent an interface between a chest wall structure and tissue of the ROI in a plurality of co-registered medical images. A completeness map of the image data within the defined surface contour during the imaging session is generated and overlaid on a graphic representation of the ROI.

  • Patent number: 10820873
    Abstract: Contrast-enhanced image data of breast tissue to be examined is generated. First two-dimensional contrast-agent-influenced x-ray projection data of the breast tissue are acquired at a first x-ray beam energy and a two-dimensional image data record is generated on the basis of the first two-dimensional x-ray projection data. Second two-dimensional contrast-agent-influenced x-ray projection data are acquired from different projection angles at a second x-ray beam energy that differs from the first x-ray beam energy and a three-dimensional tomosynthesis image data record of the breast tissue is reconstructed from the detected second two-dimensional x-ray projection data. Subsequently, a two-dimensional synthetic mammogram is calculated on the basis of the three-dimensional tomosynthesis image data record and a two-dimensional dual-energy mammogram is established by subtracting the image data of the synthetic mammogram from the image data of the two-dimensional image data record.

  • Patent number: 10709896
    Abstract: System and method for treating hemorrhoidal piles, addressing both cause and symptoms, by endoluminal/interstitial application of energy are disclosed. The dilated blood arteries in anal/rectal region are irradiated from inside the pile using (laser) energy for minimal pain/discomfort. The center of the pile is irradiated over a certain diameter, absorbing energy; and is denatured causing volume reduction. Central vessels located in the same diameter are obliterated immediately, relieving bleeding. During treatment, new connective tissue replaces the coagulated tissue. Closing inflowing arteries further shrinks piles in weeks to three months. Complications are highly diminished. A hand-piece and a fiber with a sharp distal tip are beneficial. Including an imaging system, (ultrasound imaging, optical coherence tomography) and an intelligent system to calculate necessary laser energy parameters help address each pile individually.
