There is currently no radiotherapy phantom capable of quantitatively assessing all components of an online adaptive radiotherapy (online ART) system in a comprehensive end-to-end test.Represented here is a novel, rigid phantom that can simultaneously evaluate an online ART system's image acquisition, deformable image registration, contour propagation, plan re-optimization, dose calculation, and beam delivery in a single process that is robust, quantitative, and convenient.

Researchers at Vanderbilt have developed a new image-guided, trackerless surgical microscope system to be used in soft tissue surgeries. The current method is to use a surgical microscope along with an image-guided system. This new design eliminates the need for a separate image-guidance system; the entire guidance environment can be realized within the microscope environment.

A team of Vanderbilt researchers has developed a novel fiducial marker for use during radiosurgery of the eye. The fiducial is a non-invasive, comfortable method for performing registration of preoperative medical images and the radiotherapy target during therapy. The device aims to remove the need for existing invasive registration procedures, while still providing accurate localization to the clinician.

Vanderbilt presents an intraoperative device for taking the guesswork out of whether or not a threaded component is securely affixed to bone. This device is an anchor driver that automatically releases upon proper seating of the anchor on the bone of interest.
