Planning, navigation and simulation systems and methods for minimally invasive therapy

摘要

Disclosed herein are planning, navigation and simulation systems and methods for minimally invasive therapy in which the planning method and system uses patient specific pre-operative images. The planning system allows for multiple paths to be developed from the pre-operative images, and scores the paths depending on desired surgical outcome of the surgery and the navigation systems allow for minimally invasive port based surgical procedures, as well as craniotomies in the particular case of brain surgery.

主权项

1. A system for planning one or more surgical trajectory paths to one or more targets in tissue within a patient's body, comprising:
a) a storage memory device configured to store therein one or more pre-operative imaging data sets from one or more imaging modalities of an anatomical portion of the patient's body, at least one of the one or more imaging data sets being one or more diffusion MRI data sets; and b) a computer processor in communication with the storage memory device programmed for
i) producing, from the one or more pre-operative imaging data sets, images and related data of a volume of the anatomical portion of the patient's body containing one or more entry points into the tissue and one or more targets to be approached, at least one of the related data being tractography of the volume of the anatomical portion produced from the one or more diffusion MRI data sets, andii) storing the images and related data of the volume; and c) a computer user interface in communication with the computer processor for
i) receiving a user selection of the one or more targets to be approached during a surgical procedure and storing locations of the one or more targets;ii) displaying the images and related data of the volume;iii) receiving a user selection of the one or more entry points into the patient's tissue;iv) producing and displaying one or more potential surgical trajectory paths from the one or more entry points to the one or more targets, and their interaction with the tractography and other selected anatomical features in the volume of the anatomical portion;v) accepting a user selection of one or more surgical trajectory paths from the one or more potential surgical trajectory paths; andvi) storing on the memory device the one or more surgical trajectory paths.
