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.

Abstract: A system may comprise one or more processors and memory having computer readable instructions stored thereon. The computer readable instructions, when executed by the one or more processors, may cause the system to receive image data including a segmented candidate target nodule, receive a seed point, and determine if the segmented candidate target nodule is within a threshold proximity of the seed point. Based on a determination that the segmented candidate target nodule is within the threshold proximity of the seed point, the segmented candidate target nodule may be identified as an identified target nodule. A target nodule boundary corresponding to the identified target nodule may be displayed.

Abstract: An exemplary system accesses a three-dimensional (3D) model of an anatomical structure, applies a first detection process to the 3D model to detect a single-layer anatomical feature in the anatomical structure, applies a second detection process, different from the first detection process, to the 3D model to detect a non-single-layer anatomical feature in the anatomical structure, and provides a representation of the anatomical structure based on the 3D model, the detected single-layer anatomical structure, and the detected non-single-layer anatomical structure. In some implementations, the representation of the anatomical structure and a representation of a potential path to be traversed by a medical instrument in the anatomical structure are displayed.
