Reduction of Brain Shift

The accuracy and expertise needed for performing surgery in the cardiothoracic system and the central nervous system are demanding. The possibility of tissue damage while performing these surgeries are high and can lead to a life-threatening situations.

Improvement in the Imaging techniques improved surgical accuracy through image-guided navigational systems. However, there are still certain possibilities for errors such as brain shift in neurosurgery and lack of complete three-dimensional understanding of the organ layout in cardiothoracic surgery.

To counter these problems, newly developed fields such as virtual reality, augmented reality, and soft tissue biomechanics, are being used extensively. Our researcher Satish studied the fluid-structure interaction strategies using finite element and finite volume methods to estimate and reduce the brain shift to improve the neuro-navigational system accuracy.
