Publication number: 20230240750Abstract: 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.Type: ApplicationFiled: May 11, 2021Publication date: August 3, 2023Inventors: Timothy D.
