摘要: Devices, systems, methods, and computer program products for performing medical procedures are disclosed herein. In some embodiments, a system for processing medical image data is configured to receive image data of a patient's anatomy. The system can select a first section of the image data, each image interval in the first section having an interval size within a predetermined size range. The system can identify a second section of the image data including at least one image interval having an interval size outside the predetermined size range. The system can generate a resampled second section by adding, deleting, and/or resampling one or more interpolated images in the second section, such that each image interval in the resampled second section has an interval size within the predetermined size range. The system can output a combined section including the first section and the resampled second section.

摘要: A method for image segmentation comprises receiving volumetric image data for an anatomical region and generating a first volumetric patch from the volumetric image data. The method also comprises generating a second volumetric patch from the first volumetric patch by weighting a plurality of volumetric units in the first volumetric patch and receiving the second volumetric patch as an input to a convolutional neural network. The method also comprises conducting a down-sampling filter process and conducting an up-sampling filter process within the convolutional neural network.

摘要: A medical system may comprise a display system, a user input device, a medical instrument, and a manipulator assembly configured to support and operate the medical instrument. The medical system may also comprise a control system. The control system may be configured to display image data corresponding to a three-dimensional anatomical region via the display system, receive a first user input to generate a first curve in the three-dimensional anatomical region via the user input device, and receive a second user input to generate a second curve in the three-dimensional anatomical region via the user input device. The control system may also be configured to determine an anatomical boundary bounded by the first curve and the second curve. The control system may also be configured to control the manipulator assembly to operate medical instrument using the determined anatomical boundary to limit movement of the medical instrument.

摘要: Devices, systems, methods, and computer program products for planning medical procedures are disclosed herein. In some embodiments, a system for planning a medical procedure includes a processor and memory operably coupled to the processor. The memory stores instructions that, when executed by the processor, cause the system to perform operations including receiving a three-dimensional model of an anatomic region of a patient and evaluating whether the three-dimensional model is suitable for use in a registration procedure to be performed in the anatomic region. The evaluating includes: analyzing a span of the three-dimensional model along at least two different directions, determining whether the three-dimensional model includes at least one segmented component corresponding to at least one structure of the anatomic region, and performing a registration between the three-dimensional model and a virtual registration data set.
