Abstract: A set of virtual images can be generated based on one or more real images and target rendering specifications, such that the set of virtual images correspond to (for example) different rendering specifications (or combinations thereof) than do the real images. A machine-learning model can be trained using the set of virtual images. Another real image can then be processed using the trained machine-learning model. The processing can include segmenting the other real image to detect whether and/or which objects are represented (and/or a state of the object). The object data can then be used to identify (for example) a state of a procedure.

Abstract: In some embodiments, methods and systems are provided for accessing a surgical dataset including surgical data collected during performance of a surgical procedure. The surgical data can include video data of the surgical procedure. Using the surgical data, a plurality of procedural states associated with the surgical procedure can be determined. For a procedural state of the plurality of procedural states, temporal information can be identified that identifies a part of the video data to be associated with the procedural state. For the procedural state of the plurality of procedural states, electronic data can be generated that characterizes the part of the video data and outputting the electronic data associated with the plurality of procedural states.

Abstract: In some embodiments, surgical data structure is accessed that includes a plurality of nodes (relating to a plurality of discrete procedural states for a surgical procedure and being associated with procedural metadata) connected by a plurality of edges. Each edge can be associated with a procedural action causing a state transition. A new node can be generated based on an identification of a new procedural state. A first and second node from the plurality of nodes can be identified, to which the new node is to be connected. Edges can be generated to connect the new node to the first and second nodes.

Abstract: Certain aspects and features of the present disclosure relate to systems and methods for accessing a surgical data structure that that includes a plurality of nodes, each associated with a procedural state, connected by a plurality of edges. The surgical data structure is used to determine a current node associated with a discrete procedural state and present relevant procedural metadata associated with the procedural state to the relevant system user. The current node is determined by receiving live surgical data, detecting a component from the live surgical data using feature extraction techniques, and identifying a current node based on the component extracted from the live surgical data. In some examples, the systems and methods retrieve a set of procedural metadata associated with the current node from the surgical data structure and transmit the set of procedural metadata to the appropriate user.

Abstract: A method and system for calibrating molecular arrays to a reference molecular array, and for subsequently calibrating the molecular arrays to maintain a constant signal-intensity-to-label-concentration ratio. In the first step of the two-step calibration method, a reference array coated with the fluorophore or chromophore used to label probe molecules is employed, while in the second step of the two-step method, a reference array coated with a stable dye is employed.

Abstract: An apparatus and method for making an array hybridization chamber that holds a thermoplastic substrate in a flat position. The apparatus employs a thermoplastic substrate having one or more support ridges. Methods of making the hybridization apparatus and chamber are also disclosed.
