Abstract: A method for optical imaging including: acquiring images with first and second sensors; acquiring an original image with the first sensor using a first exposure time contained in a first measurement interval; acquiring images sequentially with the second sensor using a second exposure time where each image is contained in a second measurement interval smaller than the first measurement interval; selecting a former image acquired at least partially during the first measurement interval and a later image acquired at least partially after the first measurement interval; identifying differences between the former and later images, creating an interpolated image by applying the identified differences to the original image, and displaying the original image acquired by the first image sensor in an initial part of a first display interval starting after the first measurement interval and displaying the interpolated image in an end part of the first display interval.

Abstract: A vertical takeoff and landing (VTOL) aircraft includes a maximum takeoff weight (MTOW) of about 1700-kg, a cruising speed of about 80-knots equivalent airspeed (EAS) to about 100-knots EAS, a nominal range of about 300-km, a nominal flight time of about 4-hours, and at least one pair of rotors configured to provide vertical thrust. Each rotor of the at least one pair includes an about 2-meter propeller diameter, a disk loading of about 67-kg/m2 to about 110-kg/m2, and an operating speed of about 1800 rotations-per-minute (RPM) to about 2700-RPM.

Abstract: A method for visualization of faint fluorescence in surgery. The method including: emitting excitation light from an excitation light source onto an operation area containing a faint fluorescence source and white light from a white light source, capturing one or more fluorescence images of the operation area at a wavelength range of fluorescence light emitted by the faint fluorescence source and one or more white light images, performing image processing on the captured images by creating a virtual region of interest in the white light image and/or the fluorescence image, wherein the fluorescence image is cut off outside the region of interest, creating one or more false color fluorescence images visible in the visible light spectrum from the one or more fluoresecence images, and creating one or more composite images by overlaying the one or more false color fluorescence images over the one or more white light images.

Abstract: A method for visualization of faint fluorescence in surgery. The method including: emitting excitation light from an excitation light source onto an operation area containing a faint fluorescence source, as well as white light from a white light source, capturing one or more fluorescence images of the operation area at a wavelength range of fluorescence light emitted by the faint fluorescence source as well as one or more white light images, performing image processing on the one or more fluorescence images and creating one or more false color fluorescence images from the one or more fluorescence images, wherein a contrast between the fluorescence light emitted by the faint fluorescence source and background is increased, and creating one or more composite images by overlaying the one or more false color fluorescence images over the one or more white light images.

Abstract: An image capturing and processing device configured to measure a fluorescence signal in a tissue of a body part, to which a fluorescent agent has been added, and to image a surface of the body part. The device including a light source, two or more image sensors configured to capture fluorescent images and visible light images of the body part. The two or more image sensors are configured in that a viewing direction and/or a perspective of the fluorescence images and the visible light images are linked via a known relationship. A processor applies a stitching algorithm on the visible light images and similarly on the fluorescence images to generate a large visible light image and a large fluorescence image.

Abstract: Computer based clinical decision support system (CDSS) and method for determining a classification of a lymphedema induced fluorescence pattern. The fluorescence image is determined from a measurement of a fluorescence signal in a tissue of a body part, to which a fluorescent agent 8 has been added. The CDSS including: an input interface through which the fluorescence image, which is specific to a patient, is provided as an input feature to an artificial intelligence (AI) model, one or more processors configured to, perform an inference operation in which the fluorescence image is applied to the AI model to generate the classification of a lymphedema induced fluorescence pattern, and a user interface (UI) through which the classification of the lymphedema induced fluorescence pattern is communicated to a user.
