Electrical Impedance Tomography for Robot-Aided Internal Radiation Therapy
- Medicine, PhysicsFrontiers in Bioengineering and Biotechnology
The feasibility of using electrical impedance tomography (EIT) as the main imaging modality during robot-aided internal radiation therapy and observations indicate that the imaging procedure is able to observe differences in tissue conductivity in a setting that approximates transperineal HDR and confirm that brachytherapy needles can be used as electrodes for this purpose.
Development of a tissue discrimination electrode embedded surgical needle using vibro-tactile feedback derived from electric impedance spectroscopy
- PhysicsMedical Biol. Eng. Comput.
The results show that the vibrotactile feedback is able to help the operator in determining the tissue the needle is in, suggesting that this may prove to be a useful supplement to the standard procedure used today.
