Background

Sacral Neuromodulation surgery is a surgery performed in pathologies such as urinary and fecal incontinence, urinary retention and constipation. An electrode is inserted through a needle in a sacral root which controls the bladder and the intestine to stimulate the efferent and afferent vias. Nowadays this process is only validated through x-ray fluoroscopy while the insertion of the needle is being performed. The main challenge of the doctor in the surgery is the placement of the needle in the correct position for proper stimulation.

We propose a new module in the Software 3D Slicer, to guide the needle intervention using as navigation system an electromagnetic tracking system.

Project Description

Objective

• A slicer module/GUI for tracking the needle in a Sacral Neuromodulation intervention.

Approach, Plan

• Use PLUS library for data (electromagnetic tracker transforms) acquisition.

• The GUI for the guidance: Is guidelet only useful with ultrasound? We have used their properties to create our GUI, hiding ultrasound properties, which is not very smart.

Progress

• Slicer development has been properly set up.
