Abstract
In a method of real-time 3-D visualization and navigation for interventional procedures a position is determined at which data will be acquired, and data is acquired at the position. Features are extracted from the acquired data. A model described by the extracted features is built or updated, wherein updating the model includes calculating at least one acquisition parameter of a set of acquisition parameters. 3-D scenes showing the interior or exterior of one or more organs are displayed using the model or data extracted from the model. A region for updating is determined.
Claims21
A method of real-time 3-D visualization and navigation for interventional procedures, comprising the steps of:
- determining a position at which data will be acquired;
- acquiring data at the position;
- extracting features from the acquired data;
- building or updating a model described by the extracted features, wherein updating the model includes calculating at least one acquisition parameter of a set of acquisition parameters;
- displaying 3-D scenes showing the interior or exterior of one or more organs using the model or data extracted from the model;
- and
- determining a region for updating.
A method of real-time 3-D visualization and navigation for interventional procedures, comprising the steps of:
- acquiring slice or volume data;
- extracting boundary locations from the acquired slice or volume data;
- building or updating a model using the extracted boundary locations, wherein updating the model includes calculating at least one acquisition parameter of a set of acquisition parameters;
- displaying 3-D scenes using the model or data extracted from the model;
- calculating a slice or volume position for updating.
A system for real-time 3-D visualization and navigation for interventional procedures, comprising:
- a graphical user interface;
- an MR scanner in data communication with the graphical user interface, wherein the MR scanner includes a real-time pulse sequence program that allows changing scan parameters during acquisition;
- and
- a controller, wherein the controller requests data from the MR scanner, and wherein the controller provides position data and at least one acquisition parameter of a set of acquisition parameters to the MR scanner.
A system for real-time 3-D visualization and navigation for interventional procedures, comprising:
- an imaging device operable to acquire data and transmit the acquired data;
- a processor, wherein the processor extracts features from the acquired data and generates a model;
- and
- a display device in data communication with the processor, the display being operable to display 3-D scenes showing the interior or exterior of one or more organs using the model or data extracted from the model.
