Non-invasive non-contact system and method for measuring health parameters
A system and method for measuring health parameters of a subject is disclosed. The system and method are based on a mirror; an image acquisition unit configured with the mirror, and comprising a thermal sensor for capturing thermal images or videos of a body part of the subject; and a processing unit to receive data packets associated with the captured thermal images or videos from the image acquisition unit to identify a region of interest of the body part in each frame of the captured thermal images and videos. Further, the processing unit extracts attributes associated with a heat intensity variation from the identified region of interest region, and compares the extracted attributes with a predetermined set of reference data to measure risk scores associated with the health parameters of the subject based on the comparison. The measured risk scores are displayed by a display unit.
SURGICAL VISUALIZATION SYSTEMS AND DISPLAYS
A medical apparatus is described for providing visualization of a surgical site. The medical apparatus includes an electronic display disposed within a display housing. The medical apparatus includes a display optical system disposed within the display housing, the display optical system comprising a plurality of lens elements disposed along an optical path. The display optical system is configured to receive images from the electronic display. The medical apparatus can include proximal cameras mounted on a frame, the cameras configured to provide a view of a surgical site from outside the surgical site. The display housing can have a height that is larger than its depth.
IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
An image processing device includes: an obtaining unit configured to obtain an image including at least one body hair; and an analyzing unit configured to analyze the image to output information indicating an orientation of the at least one body hair included in the image.
Patient monitor
Images obtained by a camera system (10) arranged to obtain images of a patient (20) undergoing radio-therapy are processed by a modeling unit (56,58) which generates a model of the surface of a patient (20) being monitored. Additionally the patient monitoring system processes image data not utilized to generate a model of the surface of a patient being monitored to determine further information concerning the treatment of the patient (20). Such additional data can comprise data identifying the relative location of the patient and a treatment apparatus (16). This can be facilitated by providing a number or retro-reflective markers (30-40) on a treatment apparatus (16) and a mechanical couch (18) used to position the patient (20) relative to the treatment apparatus (16) and monitoring the presence and location of the markers in the portions of the images obtained by the stereoscopic camera (10).
REAL-TIME REGISTRATION USING NEAR INFRARED FLUORESCENCE IMAGING
A system for performing a surgical procedure includes a camera configured to capture real-time near infrared images, an injection system configured to inject a fluorescent dye into a patient's blood stream, and a workstation operably coupled to the camera for retrieving a three-dimensional (3D) model of the patient's anatomy based on pre-procedure images, retrieve an indication of a targeted critical structure within the 3D model, observe, using the captured real-time near infrared images, perfusion of the fluorescent dye through tissue to identify critical structures illuminated by near-infrared light, and register the real-time near-infrared images to the 3D model using the identified illuminated targeted critical structure in the real-time near infrared images captured by the camera and the identified targeted critical structure in the 3D model as a landmark.
Miniaturized mobile, low cost optical coherence tomography system for home based ophthalmic applications
Improved optical coherence tomography systems and methods to measure thickness of the retina are presented. The systems may be compact, handheld, provide in-home monitoring, allow the patient to measure himself or herself, and be robust enough to be dropped while still measuring the retina reliably.
STORAGE MEDIUM, IMAGE MANAGEMENT APPARATUS, READING TERMINAL, AND IMAGE MANAGEMENT SYSTEM
A non-transitory computer readable storage medium stores instructions causing a computer that processes information stored in an image management apparatus to execute: creating a synthesized image by synthesizing a scout image in a predetermined region of a slice image, the slice image and the scout image being stored in the image management apparatus, and the scout image specifying a cross-section position of the slice image.
Multispot monitoring for use in optical coherence tomography
Optical coherence tomography (herein “OCT”) based analyte monitoring systems are disclosed. In one aspect, techniques are disclosed that can identify fluid flow in vivo (e.g., blood flow), which can act as a metric for gauging the extent of blood perfusion in tissue. For instance, if OCT is to be used to estimate the level of an analyte (e.g., glucose) in tissue, a measure of the extent of blood flow can potentially indicate the presence of an analyte correlating region, which would be suitable for analyte level estimation with OCT. Another aspect is related to systems and methods for scanning multiple regions. An optical beam is moved across the surface of the tissue in two distinct manners. The first can be a coarse scan, moving the beam to provide distinct scanning positions on the skin. The second can be a fine scan where the beam is applied for more detailed analysis.
Instrument for acquiring co-registered orthogonal fluorescence and photoacoustic volumetric projections of tissue and methods of its use
Disclosed are instruments and methods for acquiring co-registered orthogonal fluorescence and photoacoustic volumetric projections of an interrogated object. In an embodiment, an instrument includes a rotary mechanism configured to rotate an interrogated object relative to an array of photoacoustic transducers and an optical detector. An optical excitation unit is configured to irradiate the interrogated object with pulses of light, inducing both fluorescence and photoacoustic responses inside the interrogated object at each of a plurality of rotational positions. The array of photoacoustic transducers includes unfocused elements arranged in a pattern along an axis of rotation, the elements configured to detect photoacoustic signals generated inside the volume of the interrogated object. The optical detector is arranged opposite to the array of photoacoustic transducers with respect to the axis of rotation and is configured to register sources of fluorescence excited inside the interrogated object. Each of the optical excitation axes form with each of the optical detection axes, and with each of the photoacoustic detection axes, angles that are between 60° and 90° so as to enable acquisition of co-registered orthogonal fluorescence and photoacoustic volumetric projections of the interrogated object.
Device and method for determining depth and concentration of a subsurface fluorescent object
A method and device for determining the depth and fluorophore concentration of a fluorophore concentration below the surface of an optically absorbing and scattering medium suitable for use in fluorescence-based surgical guidance such as in tumor resection is described. Long-wavelength stimulus light us used to obtain deep tissue penetration. Recovery of depth is performed by fitting measured modulation amplitudes for each spatial frequency to precomputed modulation amplitudes in a table of modulation amplitudes indexed by optical parameters and depth.
