An Integrated Environment for Rehearsal And Planning of Surgical Interventions

Objective

IERAPSI provides a novel approach to computerised image-guided surgical planning. The project will provide an environment for visualising and interacting with the anatomy and pathology demonstrated by advanced imaging methods and VR techniques. At the same time IERAPSI will allow rehearsal of procedures on an individual patient and the development of training systems based on individual patient's variations in anatomy and pathology. In this way it is intended that IERAPSI will provide an essential surgical planning tool, which can be used in any case prior to operation. In order to achieve this the system will be rapid, flexible, easy to use, simple to understand and capable of seamless integration of image reporting, analysis, visualisation and VR tools.

Objectives:
IERAPSI will provide an interactive computerised environment for the planning and rehearsal of surgical procedures in individual patients. The most important goal is to contribute to the European Community's social objectives by improving the provision of health and life through the introduction of modern science technology into healthcare. Specifically, IERAPSI will provide:
* An interactive visualisation environment to allow the production of 3D surgical planning data sets
* Image review and analysis tools to allow the surgical review of CT, MRI and angiographic examinations in an interactive 2D and 3D manner
*An integrated suite of image segmentation and visualisation tools intended to allow rapid and accurate identification of individual structured based on their imaging characteristics
*A physics based surgical simulation system with visual and haptic feedback for training surgeons to perform operations on individual patient data.

A further use of IERAPSI will be in patient education and consent. The simulators can be used to prepare a patient before a surgical operation to explain the procedure that they about to undergo using renderings of their own body. This can reduce patients and is an excellent example of how information technology has immediate practical benefit.

Work description:
The project will focus on the implementation of an interactive computerised environment for the planning and rehearsal of surgical procedures. The implementation will be generic in order to adapt and re-use components easily for other applications.

The work will follow this general strategy:
* Specification of the approach itself and implementation of core components. This will include an ergonomic task analysis
* Development of an integrated suite of tools for pre-operative planning
* Development o an infrastructure for training and rehearsal of surgical operations working on data produced by the pre-operative tools
* Engineering of an autostereoscopic display subsystem suitable for the presentation of medical data in stereo 3D
* Integration o the pre-operative tools and the training infrastructure on the basis of a standardised data format to facilitate the exchange of processed medical data between IERAPSI components and/or external entities

* Validation of the approach through demonstrative applications having a significant clinical impact:
- as a series of tools to be used for pre-operative planning;
- as a simulation system to be used for training surgical procedures;
- as an integrated system for planning and rehearsal of surgical procedures.

To meet the project objectives IERAPSI will address surgery of the petrous bone
- a common surgical site with complex anatomy.

It requires range of surgical procedures with escalating levels of complexity:
Mastoidectomy;
Cochlear implantation and Acoustic Neuroma.

Both surgical planning and surgical simulation will be addressed. The usefulness of the IERAPSI system will be assessed by a small-scale clinical trial - one for each of the 3 clinical exemplars. Each trial will be conducted at one of the main end-user sites (University of Pisa, University of Manchester and Institute of Laryngology and Otology). Clinical trials will be performed using a standard bank of clinical test data.

Milestones:
* An open software architecture for implementing clinical simulators
* Three clinical prototypes implemented on top of the generic infrastructure treating common operative procedures on the petrous bone
* An autostereoscopic display environment
* A technical recommendation on how to support processing of medical imaging data
* Training tools for surgeons that want to have a precise knowledge of the specific patient anatomy.
