Systems and methods for in-operating-theatre imaging of fresh tissue resected during surgery for pathology assessment

The disclosed technology brings histopathology into the operating theatre, to enable real-time intra-operative digital pathology. The disclosed technology utilizes confocal imaging devices image, in the operating theatre, “optical slices” of fresh tissue—without the need to physically slice and otherwise process the resected tissue as required by frozen section analysis (FSA). The disclosed technology, in certain embodiments, includes a simple, operating-table-side digital histology scanner, with the capability of rapidly scanning all outer margins of a tissue sample (e.g., resection lump, removed tissue mass). Using point-scanning microscopy technology, the disclosed technology, in certain embodiments, precisely scans a thin “optical section” of the resected tissue, and sends the digital image to a pathologist rather than the real tissue, thereby providing the pathologist with the opportunity to analyze the tissue intra-operatively. Thus, the disclosed technology provides digital images with similar information content as FSA, but faster and without destroying the tissue sample itself.

METHODS AND SYSTEMS FOR SLIDE PROCESSING

Various examples of systems and methods are provided for slide processing. In one example, among others, a system for processing microscope slides includes a slide positioner that can adjust a position of a slide and a slide treatment system that can dispense a micro stream of a fluid at a location on the slide when the slide is positioned beneath a jet nozzle of the slide treatment system. The system can include a slide sled that can align a smearing slide with a surface of the slide including a fluid sample is disposed, and support the smearing slide at a predefined angle with respect to the surface of the slide. In another example, a method includes obtaining a slide including a sample disposed on a surface, positioning the slide below to a jet nozzle, and dispensing a micro stream of a fluid onto the sample using the jet nozzle.

Virtual Slide Stage (VSS) Method For Viewing Whole Slide Images

Embodiments provide slide navigation technology that addresses challenges in digital pathology of navigating and viewing high resolution slide images. Example systems comprise a virtual slide stage (VSS) having at least one sensor that detects user movement of a target placed on the VSS, and an input component, coupled to the VSS, which provides quick function movement control of the target via quick functions. The systems also comprise a connector component that connects the VSS to a user device and transmits output from the at least one sensor and input component to the user device. The systems further comprise a computer processor, in communication with the VSS, which processes the output using a computational model to generate data representing movement profiles of the target. The computer processor executes a software component, causing the output, translated based on the movement profiles, to be relayed via a viewing application on the user device.

Wafer for carrying biological sample

A wafer for carrying a biological sample includes a pair of circular discs, at least one of the discs being transparent. The wafer also includes a gap between the discs adapted to receive a biological sample. The compact circular shape of the wafer makes it particularly suited for use in a portable device in which the wafer is rotated to enable a camera to image different areas of the sample between the discs. The gap may be sized to pull a biological sample into the gap by capillary action.

VACUUM MANIFOLD FOR FILTRATION MICROSCOPY

A vacuum manifold for filtration microscopy includes a manifold top having multiple openings, and a capture membrane positioned above and spaced apart from the manifold top, where the capture membrane is configured to deflect into contact with a surface of the manifold top when a negative pressure is applied to the multiple openings. A method for filtration microscopy includes the steps of providing a vacuum manifold including a manifold top having a plurality of openings, and a capture membrane positioned above and spaced apart from the manifold top; applying sample drops to sample spots on the membrane, the sample spots positioned above the plurality of openings; applying a negative pressure to the openings such that the capture membrane contacts a surface of the manifold top; and optically imaging particulates on the capture membrane.

Method and system for implementing augmented reality (AR)-based assistance within work environment

Novel tools and techniques are provided for implementing augmented reality (AR)-based assistance within a work environment. In various embodiments, a computing system might receive, from a camera having a field of view of a work environment, first images of at least part of the work environment, the first images overlapping with a field of view of a user wearing an AR headset; might analyze the received first images to identify objects; might query a database(s) to determine a task associated with a first object(s) among the identified objects; might generate an image overlay providing at least one of graphical icon-based, text-based, image-based, and/or highlighting-based instruction(s) each indicative of instructions presented to the user to implement the task associated with the first object(s); and might display, to the user's eyes through the AR headset, the generated first image overlay that overlaps with the field of view of the user's eyes.

CARTRIDGE POSITIONING SYSTEM

A system for positioning a cartridge is disclosed. The system has a drive rod with a body having a first axis and a groove formed in the body. The groove has a first portion that is not perpendicular to the first axis and a second portion that is perpendicular to the first axis. The system also includes a collar that coupled to the drive rod. The collar has an element configured to engage the groove. Rotation of the drive rod with respect to the collar while the element is engaged in the first portion of the thread causes the collar to move with respect to the first axis. Rotation of the drive rod with respect to the collar while the element is engaged with the second portion of the thread causes the collar to remain stationary with respect to the first axis.
