A device for providing reference information in laser speckle medical imaging of tissue of a subject can include a support that includes a marker for image recognition and a speckle target region that is nontransparent to light in a first illumination wavelength range and that generates a speckle pattern when illuminated with light in the first wavelength range. The support can be configured to be attachable to tissue of the subject.

An optical system for the detection of skin disease, such as melanoma, acquires images of a lesion on a subject's skin at different wavelengths and utilizes a sweeping arm rotating about the lesion in a clock-like sweep to produce diagnostically relevant metrics and classifiers from the image data so as to enhance detection of the skin disease.

A probe for detecting cancerous tissue, the probe including an illuminator, an optical spectrum analyzer, and an indicator for indicating whether cancerous tissue has been detected in reflected spectrum analyzed by the optical spectrum analyzer. A method for detecting cancerous tissue, the method including providing a probe including an optical spectrum analyzer, placing the probe to include tissue-to-be-tested within a Field-Of-View (FOV) of the spectrum analyzer, optically illuminating the tissue-to-be-tested, analyzing light reflected from the tissue-to-be-tested, and determining whether or not cancerous tissue is detected in the FOV. Related apparatus and methods are also described.

The present disclosure relates to a method and system for reducing radiation dose in image acquisition. The method may include obtaining first image data of a subject related to a first scan of the subject. The first scan may be of a first type of scan. The method may include reconstructing a first image of the subject based on the first image data and generating a dose plan of a second scan based on the first image. The second scan may be of a second type of scan. The method may also include obtaining second image data of the subject related to the second scan of the subject. The second scan may be performed according to the dose plan.

A symptom recording apparatus includes a control unit configured to perform control to output guidance on a method for confirming a body symptom of a user, receive an input operation of a confirmation result of the body symptom, and record the received confirmation result.

A system and method are provided for display of medical image data, with the display of the medical image data being determined on the basis of schematic image data of a schematic representation of an anatomical structure. The schematic representation may provide a particular view of the anatomical structure. The type of anatomical structure and the view of the anatomical structure provided by the schematic representation may be determined based on one or more image features in the schematic image data. The view may be characterized as a geometrically-defined perspective at which the anatomical structure is shown in the schematic representation. An output image may be generated showing the anatomical structure in the medical image data in accordance with said determined geometrically-defined perspective. A user may thus be provided with a display of medical image data which is easier to interpret having considered said schematic representation.

A computer-implemented system is provided that includes at least one processor that is adapted to analyze a plurality of frames from a real-time video to identify frames during which an operator is interacting with an image device to examine areas of a patient. The at least one processor is further configured to generate, from the identified frames, data representations of a first area examined by the operator interacting with the image device and further generate data representations of one or more further areas examined by the operator interacting with the image device. The at least one processor is also configured to aggregate the data representations of the first area with the data representations of the one or more further areas and determine, using the aggregated data representations, an examination quality level of the areas examined by the operator and present, on a display device during the medical procedure, a graphical representation indicating the examination quality level of the areas examined by the operator.

Methods and apparatuses for characterizing life quality of a living entity via hyper-spectral imaging and analysis, and applications thereof, such as managing life quality of a living entity. Includes acquiring hyper-spectral imaging data and information of: anatomical features of the living entity, and substances consumable by the living entity; generating and maintaining a living entity-specific database containing data and information about the living entity; processing acquired living entity anatomical feature and consumable substance hyper-spectral imaging data and information, and living entity data and information; using processed data and information to generate living entity life quality data and information characteristic of life quality of the living entity. Applicable to any living entity (human, animal, plant). Applicable to integrated microelectromechanical (MEM) [chip level] components in desk top devices or miniature smart/intelligent devices. Applicable to generating, processing, or/and utilizing demographic data and information about living entities and consumable substances.

Example methods and systems may be used intraoperatively to help surgeons perform accurate and replicable surgeries, such as knee arthroplasty surgeries. An example system combines real time measurement and tracking components with functionality to compile data collected by the hardware to register a bone of a patient, calculate an axis (e.g., mechanical axis) of the leg of the patient, assist a surgeon in placing cut guides, and verify a placement of an inserted prosthesis.

Systems and methods are disclosed to objectively identify sub-second behavioral modules in the three-dimensional (3D) video data that represents the motion of a subject. Defining behavioral modules based upon structure in the 3D video data itself—rather than using a priori definitions for what should constitute a measurable unit of action—identifies a previously-unexplored sub-second regularity that defines a timescale upon which behavior is organized, yields important information about the components and structure of behavior, offers insight into the nature of behavioral change in the subject, and enables objective discovery of subtle alterations in patterned action. The systems and methods of the invention can be applied to drug or gene therapy classification, drug or gene therapy screening, disease study including early detection of the onset of a disease, toxicology research, side-effect study, learning and memory process study, anxiety study, and analysis in consumer behavior.
