Abstract: Medical instrument guidance systems and associated devices and methods are disclosed herein. In some embodiments, a method for providing guidance for percutaneous access to a target within an anatomic structure, includes receiving point cloud data from a sensor system coupled to an internal instrument as the internal instrument is moved within the anatomic structure; generating a 3D model of the anatomic structure based at least in part on the point cloud data; and receiving information for identifying a substructure within the 3D anatomic model. The substructure can provide access to the target. The method can further include determining an entry to the substructure; determining an approach path through the entry; and providing a graphical representation of the approach path.

Abstract: 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.
