Abstract: A system and method for planning a configuration of an object relative to a subject are disclosed. Image data comprising at least a first region and a second region may be accessed and displayed on a graphical user interface. A region of interest (ROI) between the first and second regions may be identified, and an ROI volume geometry may be determined based on the image data. A set of models of candidate objects, including a rigid portion and a configurable portion, may be accessed. One or more adjustments of the configurable portion of at least one candidate object relative to the ROI volume geometry may be simulated. Candidate objects may be evaluated according to one or more fit criteria, and a visualization of the adjustments together with a ranked list of candidate objects may be output. The system provides technological improvements for computer-assisted planning and object selection using image-based data.

Abstract: Disclosed is a system to assist in a procedure. During the procedure an object may be moved relative to a subject, such as being positioned and/or placed within a subject. The system and related method may be used to assist in displaying and/or determining a pose of the object relative to a subject, such as rigid portions of a subject.

Abstract: Devices, systems, and methods to verify a magnetic field phase drift and to check for proper function of a laser fiber cooling system during laser ablation therapy are disclosed. The laser fiber cooling system includes a cooling catheter insertable into laser ablation target tissue, a coupling assembly to define fluid channels, inflow and outflow ports, a fluid pump to pump fluid through the laser fiber cooling system, a fluid source, a first sensor to measure an inflow fluid parameter, a second sensor to measure an outflow fluid parameter, and a processor. Methods of verifying and checking include measuring the fluid parameter, comparing the inflow and outflow parameter measurements to determine a comparison value, comparing the comparison value to a tolerance range, and signaling a user when the comparison value is outside of the tolerance range.

Abstract: Devices and systems used to ablate tissue of a tumor using laser energy are disclosed. The devices and systems include a laser probe and a magnetic resonance (MR) safe temperature probe. The MR safe temperature probe includes an optical sensor. A bone anchor fixture separates the laser probe and the MR safe temperature probe to prevent interference in the MR safe temperature probe data. Proton Resonance Frequency (PRF) thermometry is used to model a temperature of a pixel of an MR image located adjacent the optical sensor. The modeled pixel temperature and the measured temperature are compared and monitored. Exceeding a threshold difference value causes an intervening action to occur.

Abstract: A display may display a region of an anatomy that is not within the field of effect of an instrument. The additional views may assist in determining a location and orientation of an instrument. The instrument may be tracked with a tracking system to make the determination of image data to display.
