Abstract: Precise nerve detection during surgery is crucial for safe operational outcomes, which largely depend on the surgeon's skills. Therefore, automatic real-time identification of anatomical structures is of great importance. However, image processing times must be kept as low as possible to be a viable solution for real-time visual identification. By using a general purpose graphics processing unit (GPGPU) implementation for birefringence mapping, the process can achieve rates of 43 frames per second (FPS); a 118×gain from a CPU implementation. Furthermore, by including a deep learning network, the complete framework can automatically detect nerves close to 12 FPS. By leveraging GPU for the processing task, the framework can run on compact devices with NVIDIA modules, such as Jetson Xavier AGX, while still achieving reasonably fast nerve identification and visualization.

Abstract: A system for obtaining medical ultrasound images of a subject comprises a probe comprising an ultrasound transducer for capturing an ultrasound image, a memory comprising instruction data representing a set of instructions, and a processor configured to communicate with the memory and to execute the set of instructions. The set of instructions, when executed by the processor, cause the processor to receive an ultrasound image taken by the probe, provide the image as input to a trained model, receive from the model an indication of whether the image comprises an image relevant to a medical diagnostic process, and determine whether to bookmark the image, based on the received indication.

Abstract: A side-open left-right-door arbitrary-opening structure of a refrigerator comprises four hinge shafts are fixedly connected at left and right sides of a refrigerator body in pairs respectively, left and right sides of upper and lower end faces of a refrigerator door are all provided with an opening neck, each hinge shaft is correspondingly placed in one opening neck, four hinge shaft stoppers are slidably arranged on the upper and lower end faces of the refrigerator door in pairs respectively, one spring is arranged between two hinge shaft stoppers in each pair, tail ends of the hinge shaft stoppers on the upper and lower end faces of the refrigerator door extend into the opening necks at the corresponding sides, and the hinge shafts at the corresponding sides are positioned in the opening necks.
