3D animation stereotactic neurosurgery

Design of 3D animations for the biopsy of a brain tumor using a stereotactic device and laser thermal ablation of the tumor.

Background:

Stereotactic in neurosurgery is a high-precision procedure that makes it possible to localize and surgically treat very specific areas of the brain. It is generally used in procedures where it is important to work precisely without damaging surrounding healthy tissue. Special imaging techniques such as CT (computed tomography) or MRI (magnetic resonance imaging) are used to create three-dimensional images of the brain.

The basic principle of stereotactic is based on the use of a fixed frame (stereotactic device / Leksell) which is combined with the imaging data. This enables the surgeon to penetrate the brain with extremely high precision, often through only small incisions. The technique is used in particular in the treatment of diseases such as tumors, movement disorders (e.g. Parkinson’s disease), epilepsy and other functional neurological disorders.

Project description:

For a patient information film at the Inselspital in Bern, we created 3D animated sequences showing the process of a biopsy of brain tissue using a stereotactic procedure and the subsequent treatment of the tissue using laser interstitial thermal therapy (LITT).

The animation starts with a lying patient with markers attached in the tempel area and a visualization of a tumor in the brain. The stereotactic frame (Leksell) fades in and is precisely aligned with the tumor based on the previously generated data from the imaging procedures. A small skin incision is made at the corresponding point on the scalp and a small opening is drilled into the skull. A probe is guided precisely into the tumor through this opening using the stereotactic device in order to take a biopsy of the tissue there.

In the final part of the animation, the tumor is treated using laser-induced interstitial thermotherapy (LITT). This involves inserting a thin laser fiber through the stereotactic device into the affected tissue and destroying the tumor cells selectively using heat.
