Abstract
An image-based correction was developed for intra-operative brain shift correction. The method utilizes ultrasound (US) imaging to update the patient specific pre-operative magnetic resonance imaging (MRI) scans, combined with a physics-based dynamic model. To quantitatively validate the imaging and modeling process, a phantom was designed that realistically simulates brain shifting patterns that occur during a brain operation. MRI and US datasets were acquired for several permutations of phantom parameters. Deformation algorithms applied to the phantom data demonstrate the efficacy of this approach to effectively update pre-operatively acquired MRI data during an operation, thus improving the accuracy of navigation.
