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.

Vanderbilt researchers have discovered a method ofmonitoring the placement of electrodes in cochlearimplants (CIs) through the use of electrical impedancemeasurements. This technology offers real-timefeedback on electrode positioning, which can beused to more accurately place electrodes duringinitial implantation, or better program the implantsafter they have been placed. These enhancementscombine to give increased hearing quality to bothnew and existing CI patients.

Vanderbilt researchers have developed a novel technology for use of a flexible fluidic actuator in MRI-guided surgical systems. This method eliminates the need for moving the patient out of the MRI machine, onto an operating table, and back in order to perform procedures. It is a safe, sterilized, and successful method to simplify MRI-guided surgical procedures.

A team of Vanderbilt engineers and surgeons have developed a new steerable needle that can make needle based biopsy and therapy delivery more accurate. A novel flexure-based tip design provides enhanced steerability while simultaneously minimizing tissue damage. The present device is useful for almost any needle-based procedure including biopsy, thermal ablation, brachytherapy, and drug delivery.
