A system and method for an improved surgical workflow development includes creating and editing a modifiable module used to direct a medical procedure through a sequence of images and functions included in the module. A plurality of users may review and/or evaluate the module to determine what, if any, edits to the module are required. Evaluations of the module may include a research evaluation, a cadaver evaluation or a clinical evaluation. A scripting tool may be used to create or edit the module, where the scripting tool includes a computer programming software application. The module may be stored on a computer-readable memory accessible by a plurality of computers and/or display devices connected to a network. In this way, the system and method provide for rapid dynamic development of surgical workflows contained in modules.

The present invention provides a method for positioning an electromagnetic tracking sensor. The method includes attaching a sensor to an anatomy, obtaining an image of the anatomy, indicating a size of each of a plurality of volumes on the image, where the volumes include a smaller and larger volume, and making a determination of whether a region of interest is encompassed by one or more of the volumes. The present invention also provides a system for positioning an electromagnetic tracking sensor. The system includes a sensor attached to a patient anatomy, an imaging modality obtaining an image of the anatomy, an image processor indicating a size of each of a plurality of volumes on the image, where the plurality of volumes includes a smaller and larger volume, and an operator making a determination of whether a region of interest is encompassed by one or more of the volumes.

Certain embodiments of the present invention provide a system and method for calibrating an instrument for an image-guided operation. The method includes placing a plurality of fiducials on an instrument, obtaining a plurality of measurements for the instrument using the plurality of fiducials, determining a representation of the instrument in a reference coordinate system using the plurality of measurements for use in tracking the instrument, and performing an image-guided operation using an image data set and representation of the instrument. The representation may be a closed form registration for the instrument. The measurements for the instrument may be obtained using a plurality of fiducials and a sensor. The fiducials may be indentations and/or grooves in the instrument. In an embodiment, the representation of the instrument is dynamically updated during an image-guided operation. In an embodiment, the representation of the instrument is compared to a computer-generated model of the instrument.

Certain embodiments of the present invention provide a method and system for improved tracking of an internal object, such as an implant or part of the anatomy, during an image-guided operation. In an embodiment, the method may include obtaining a plurality of fiducials for an internal object from a plurality of projection views, obtaining a plurality of measurements for the internal object using the plurality of fiducials, forming a three-dimensional model of the internal object using the plurality of measurements from a plurality of projection views for use in tracking the internal object, and performing an image-guided operation using an image data set and a three-dimensional representation of the internal object. The fiducials may be indentations, curves, grooves and/or identifying features in the internal object. In an embodiment, the representation of the internal object is compared to a computer-generated model of the internal object.

A system and method for positioning a medical imaging unit is disclosed. The method may include accessing data from a plurality of sensors. The method may also include computing an optimal position for the medical imaging unit to acquire images of a point of interest. The computation may be based on data from plurality of sensors and information for calibrating the point of interest with at least one sensor. The method may also include computing instructions for manipulating the medical imaging unit from a first position to an optimal position. In an embodiment, the instructions may be displayed for a user to manually position the medical imaging unit. Alternatively, the instructions may be sent to an electric motor to position the medical imaging unit, or the electric motor may provide force feedback to guide a user to position the medical imaging unit in an optimal position.

Certain embodiments of the present invention provide systems and methods for implant distance measurement. Certain embodiments of a method provide determining a tool trajectory, comparing the trajectory to one or more measured distances stored in memory to identify a requested distance measurement, and indicating the requested distance measurement to a user based on a matched trajectory. Certain embodiments of a system provide a processor configured to determine a tool trajectory with respect to a region of interest. The processor compares the trajectory to one or more measured distances between implants stored in memory to identify a requested distance measurement. The system also includes a display configured to display an image including the implants and the requested distance measurement to a user.
