Abstract: A guidance system for targeted interventions using medical instruments may include an optical unit positioned such that a desired area of intervention is within a field of view. A control unit having a touch screen display, may be communicatively coupled with the optical unit and configured to receive a real time image of the area of intervention, and further configured to (i) receive MRI volume representations of the desired area of intervention, (ii) register any multi modal markers that appear in the field of view, (iii) generate guidance feedback images comprising a plurality of image elements based on the MRI volume representations and (iii) to transmit the guidance feedback images to the projector. The projector in turn directs at least one of the guidance feedback image elements onto the area of intervention responsive to receipt of the guidance feedback images from said control unit.

Abstract: An image guided surgical system includes a marker attachable to and removable from an elongated surgical tool having a shaft, and at least one camera, and an image processing system in communication with the camera configured to obtain an image of the surgical tool. The image processing system is configured to operate in a calibration mode to generate a template and display the template on a display device and to receive a user input, after the image of the surgical tool is aligned to the template, to adjust a length of the template to substantially match a length of the surgical tool. A storage device in communication with the image processing system is included to store calibration information that associates a position of the marker with a position of the tip of the shaft of the surgical tool based on the adjusted length of the template.
