摘要： The present disclosure is directed to techniques for medical imaging image presentation. The techniques include obtaining, for a target area including a first target, an image of the target area that is taken without a contrast agent and an image of the target area that is taken with a contrast agent. The techniques also include subtracting the image that is taken with a contrast agent from the image that is taken without a contrast agent to obtain a subtraction image; extracting a contour of a second target from the subtraction image, to obtain a contour image of the second target; and registering, based on a same marker, the contour image of the second target and a currently-acquired (e.g. real-time) image, and then displaying the images in a superimposed manner. The technical solutions in the embodiments of the present disclosure improve the efficiency of treatment based on radiological images.

摘要： Provided is a bending angle calculation method capable of saving a worker time and effort. The bending angle calculation method includes: an image capturing step (S1) of capturing an image of a pipe in which a first pipe and a second pipe are joined together by a joint; a derivation step (S3) of deriving, from the image, a laying direction straight line corresponding to a laying direction of the pipe; and a calculation step (S4) of calculating, as a bending angle at the joint, a crossing angle between a laying direction straight line of the first pipe and a laying direction straight line of the second pipe.

摘要： A method for determining a quality of a surface in the surroundings of a transportation vehicle, wherein three-dimensional surface coordinates of the surface are generated using a sensor assembly. In the method, an approximation of the course of the curvature of the surface in at least one direction is obtained based on the surface coordinates and the surface coordinates are classified to characterize the quality of the surface using the course of the curvature and/or vertical distances of the approximation of the course of the curvature from the three-dimensional surface coordinates. A device for carrying out the method.

摘要： Augmentable and manipulable modeling of equipment provides a three dimensional, manipulable base model image of an equipment specimen on a display system using optical base model data obtained using a computing system. Base model data collection can be user-controlled to permit changing spatial aspects of the base model image (size, perspective, orientation). User inputs concerning functions, conditions and the like can be transmitted from a model control unit to the computing system via a two-way communication link, generating augmenting data that is combined with the base model data to render augmented three dimensional models. User inputs also can be received directly by the computing system, for example using a display system touchscreen. Augmenting data received by the computing system and/or display system also can be transmitted via the communication link to the model control unit. Such implementations permit realistic simulation of the effects of a control system on a real world system, equipment, etc.

摘要： Disclosed herein are systems and methods for synthesizing a diamond using a diamond synthesis machine. A processor receives a plurality of images of a diamond during synthesis within a diamond synthesis machine, each of the plurality of images captured within a time period. The processor executes a diamond state prediction machine learning model using the plurality of images to obtain a predicted data object, the predicted data object indicating a predicted state of the diamond within the diamond synthesis machine at a time subsequent to the time period. The processor detects a predicted defect, a number of defects, defect types, and/or sub-features of such defects and/or other characteristics (e.g., a predicted shape, size, and/or other properties of predicted contours for the diamond and/or pocket holder) of the predicted state of the diamond. The processor adjusts operation of the diamond synthesis machine.
