|Objective||Approach and Plan||Progress and Next Steps|
The project consists in a reliable and time-efficient pre-operative path planner for steerable catheters, intended to be used in neurosurgical applications. The algorithm estimates a pathway from an entry to a target point within the 3D space defined by the brain volume in accordance to specific optimality parameters and constraints, as the geometric and kynodynamic characteristics of the catheter, the distance from inner brain structures (e.g. the main blood vessels) and the total path length.
The workflow consists in the following steps:

Background and References
The proposed path planning solution finds a possible direct implementation in the EDEN2020 project, a recently founded EU project (GA No. 688279), which aims to develop an innovative system from treating glioblastoma – a highly malignant tumor involving the central nervous system – through a pioneering steerable catheter (see figure above).
