Abstract :
A method for in-vitro size estimation of protein clots generated by brain electrodes is presented. Radiofrequency generated thermal brain lesions are widely used in functional neurosurgery and in-vitro tests are used to confirm the electrodes´ ability to generate lesions. To be able to estimate the size of protein clots generated in-vitro by brain electrodes, a computer-assisted video system was set up. The size estimation is carried out by software using two captured images of the protein clot. The “true” length and width (9.5 mm) of a sphere as measured with a slide-caliper differed at the most 0.5 mm (5%) and 0.3 mm (3%) respectively, all random errors fall within 2s.d
