A system for providing surgical planning and guidance with three-dimensional visualization is disclosed. In particular, the system obtains an image set of an anatomy of interest of a subject, and renders the image set on a user interface using volume rendering. Notably, the system accomplishes the foregoing without generating surface models or conducting bone contouring. The system may, during generation of an implant plan for implanting an implant onto the anatomy of interest, suggest landmark points in the volume rendered image set. Once the landmark points are confirmed, the system may facilitate implant positioning via implant controls. The system conducts a registration process to confirm a match between the physical anatomy of interest and the information contained in volume-rendered image set in the plan. If there is a match, the system may facilitate performance of a surgical procedure for implanting the implant onto the anatomy of interest of the subject.

System and method for providing surgical planning and guidance with three-dimensional visualization

An apparatus and method for surgical tracking comprises an imaging device that generates an image of a tissue volume; an electromagnetic (EM) sensor that creates a reference frame for EM tracking in three dimensions; at least one EM sensor adapted to be attached to the tissue to track local deformation and movement of the tissue volume; a processor that registers the image with the EM-tracked tissue volume and surgical tool in real time, and produces an output; and a feedback device that provides feedback about the location of the surgical tool relative to the tissue volume, based on the processor output. Embodiments are particularly useful in soft tissue, such as breast, where deformation before and during a procedure such as tumor resection complicate tracking of the tissue volume and a surgical tool.

Real-time surgical navigation

Provided are apparatus and methods for tracking a volume of interest in three dimensions in real time, using fewer than 6 DOF tracking information together with an external 6 DOE coordinate system. The apparatus and methods described herein provide more accurate, smaller, and less expensive tracking systems than prior approaches based on full 6 DOF tracking comprising translation and full orientation information. Embodiments may be used in applications such as surgical navigation, gaming, robotics, motion capture, and training.

A method for segmenting bones on magnetic resonance (MR) images includes retrieving an MR image and performing an enhancement process on the MR image to generate a bone enhanced MR image. The bone enhanced MR image is then registered to a computer tomography (CT) based bone atlas. An MR image with bone segmentation is generated by segmenting the bone enhanced MR image using the CT based bone atlas as a mask. The MR image with bone segmentation may be presented on a display.
