A surgical planning tool evaluates a volumetric image of the skull to identify landmarks and define surgical corridors that can be compared and visualized for access to the skull for removal of tumors and the like.

Method and apparatus for evaluating surgical corridors in the skull

The present disclosure includes systems and methods for creating positron emission tomography (PET) images. The method includes receiving at least one PET image of a subject created from PET data acquired from the subject, creating an attenuation correction map using the at least one PET image, and reconstructing PET data using the attenuation correction map and the at least one PET image to generate an attenuation corrected PET image.

Deep learning based data-driven approach for attenuation correction of pet data

A system and method for an electron paramagnetic resonance imaging (EPRI) system includes a magnet configured to apply a static magnetic field to a subject to be imaged and a gradient coil configured to apply a magnetic field gradient to the static magnetic field. The system also includes a parallel plate waveguide (PPWG) configured to use a traveling wave to generate a radio frequency (RF) magnetic field over a volume of interest (VOI) in the subject to elicit EPRI data from the VOI and a processor configured to reconstruct the EPRI data into an image of the VOI.

A system and method for determining an actual gradient field generated by a magnetic resonance imaging (MRI) system when controlled to produce a prescribed gradient field is provided. The techniques include using the prescribed gradient field, controlling the MRI system to perform a phase encoding including a gradient that is scaled along each direction desired to be measured over a selected number of encoding times and acquiring one-dimensional (1D) data using a prescribed k-space trajectory during the phase encoding. The 1D data is used to determine scaling factors between encoding times that correlate to actual k-space trajectories achieved when controlling the gradient coils to perform the phase encoding based on the desired gradient field and a report is generated that provides a measure of the actual gradient field generated when controlling the MRI system to produce the prescribed gradient field.

Telemetrical control of a robotic interventional device for minimally invasive surgical procedure is based on an operative interaction between a tracking sub-system, MRI sub-system, navigation sub-system and the robotic interventional device. The tracking sensor sub-system is integrated with the interventional device to produce tracking information corresponding to the robotic interventional device location in the operative site. The navigation sub-system integrates the tracking information with the real-time images of the operative site produced by the MRI sub-system, and displays the integrated information to a user, to enable the telemetrical control of the interventional device for performing an intended procedure (biopsy, tissue resection, etc.). The navigation sub-system, based on the integrated real-time tracking information and real-time images, calculates and dynamically updates coordinates of subsequent imaging slices.
