Abstract: Described herein are systems, methods, and instrumentalities associated with automatically annotating a 3D image dataset. The 3D automatic annotation may be accomplished based on a 2D manual annotation provided by an annotator and by propagating, using a set of machine-learning (ML) based techniques, the 2D manual annotation through sequences of 2D images associated with the 3D image dataset. The automatically annotated 3D image dataset may then be used to annotate other 3D image datasets upon passing a readiness assessment conducted using another set of ML based techniques. The automatic annotation of the images may be performed progressively, e.g., by processing a subset or batch of images at a time, and the ML based techniques may be trained to ensure consistency between a forward propagation and a backward propagation.

Abstract: Described herein are systems, methods, and instrumentalities associated with automatically annotating a 3D image dataset. The 3D automatic annotation may be accomplished based on a 2D annotation provided by an annotator and by propagating the 2D annotation through multiple images of a sequence of 2D images associated with the 3D image dataset. The automatically annotated 3D image dataset may then be used to annotate other 3D image datasets based on similarities between the first 3D image dataset and the other 3D image datasets. The automatic annotation of the first 3D image dataset and/or the other 3D image datasets may be conducted based on one or more machine-learning models trained for performing those tasks.

Abstract: Click based contour editing includes detecting a selection input with respect to an image presented on a graphical user interface; designating an area of the image corresponding to the selection input as a region of interest; detecting at least one other selection input on the graphical user interface with respect to the image; determining if the at least one other selection input is within the region of interest or outside of the region of interest; and if the at least one other selection input is within the region of interest, excluding the portion of the image corresponding to the other input; or if the other selection input is outside of the region of interest, including the portion of the image corresponding to an area of the image associated with the other selection input.

Abstract: Systems, methods and instrumentalities are described herein for automatically devising and executing a surgical plan associated with a patient in a medical environment, e.g., under the supervision of a medical professional. The surgical plan may be devised based on images of the medical environment captured by one or more sensing devices. A processing device may determine, based on all or a first subset of the images, a patient model that may indicate a location and a shape of an anatomical structure of the patient and determine, based on all or a second subset of the images, an environment model that may indicate a three-dimensional (3D) spatial layout of the medical environment. The surgical plan may be devised based on the patient model and the environment model, and may indicate at least a movement path of a medical device towards the anatomical structure of the patient.

Abstract: A method for surgery planning is provided. The method may include: generating a surgery video displaying a process of a virtual surgery performed by a virtual surgical robot on a virtual patient based on a surgery plan relating to a robotic surgery to be performed on a patient by a surgical robot; transmitting the surgery video to a display component of an XR assembly used to render the surgery video for display to a user; recording one or more actions that the user performed on the virtual surgery based on user input received via an input component of the XR assembly; modifying the surgery plan based on the one or more recorded actions; and causing the surgical robot to implement the robotic surgery on the patient according to the modified surgery plan.

Abstract: A power management apparatus for a workflow to enable low power MR patient positioning on edge devices is disclosed. The power management apparatus changes an operational mode of an edge device from a first power mode to a second power mode after a defined time-interval. The power management apparatus further controls the edge device to capture a first image of a first scene. The power management apparatus further determines a trigger point based on a detection of a plurality of objects in the captured first image. The power management apparatus further changes the operational mode of the edge device from the second power mode to a third power mode to control a consumption of electric power while a set of operations is executed at the edge device. The operational mode of the edge device may be changed at the determined trigger point.

Abstract: A system and method for visualizing anatomical structure of a patient during a surgery are provided. An anatomical image and a first optical image of a patient may be obtained. The anatomical image may be captured by performing a medical scan on the patient before a surgery of the patient, and the first optical image may be captured during the surgery. A target image may be generated by combining the anatomical image and the first optical image. The target image may be rendered based on a viewpoint of a target operator of the surgery. A display device may be directed to display the rendered target image.

Abstract: The present disclosure provides systems and methods for medical assistant. The systems may obtain position information of a target inside a subject during an operation. The systems may also determine depth information of the target with respect to an operational region of the subject based on the position information. The systems may further direct an optical projection device to project an optical signal representing the depth information on a surface of the subject.

Abstract: The present disclosure provides a method for surgical automation. The method may include: obtaining video data generated in a surgical process using a camera; identifying a surgical stage in the surgical process based on the video data; and triggering an activation of a surgical equipment used for a surgical operation and/or providing a guidance of the surgical operation based on the surgical stage.

Abstract: A method for remanufacturing a pot broaching tool includes re-grinding cutting teeth on a cutting side of a used pot broaching tool, cool laser welding a rough milled shim to a bottom side of the used pot broaching tool, and grinding the cool laser welded rough milled shim such that an outer surface of the cool laser welded milled shim has a high polished surface. An inner surface of the rough milled shim has an Ra surface finish between 250 and 30 microinches and the ground outer surface of the rough milled shim has a flatness tolerance within +0/?0.0002 inches. Also, the method can include installing the remanufactured pot broaching tool in a pot without the use of a thin shim between the outer surface of the cool laser welded milled shim and an inner surface of the pot.

Abstract: A remanufactured pot broaching tool includes an elongated bar with a cutting side and a bottom side spaced part from the cutting side. A milled shim is cool laser bonded to the bottom side of the elongated bar. The milled shim has a thickness between 0.0625 inches and 0.500 inches and a flatness tolerance within +0/?0.0002 inches. A tolerance of a height dimension of the remanufactured pot broaching tool between an outer surface of a set of teeth on the cutting side and the outer elongated surface of the milled shim cool laser welded to the bottom side of the elongated bar is +0/?0.0002 inches.

In accordance with embodiments of the present invention, content items contained in the requested web content may be dynamically analyzed and classified according to their requirement for individual users. Web content items with different requirements are transmitted to the users based on protocols having different transportation characteristics. Those important content items are transmitted based on a more accurate, reliable protocol, thereby ensuring the quality of transmission. Those unimportant content items are transmitted based on a protocol with less or without guarantee of transmission accuracy. In this way, response delays can be reduced. Moreover, even if part or all of the unimportant content items are lost or delayed, the user experience can be maintained on an acceptable level.
