Preparation, assistance and imaging protocols for robotically assisted MR and CT-based procedures

To achieve millimetre accuracy and targeting precision of instrument positioning during image- guided ( MRT and CT) percutaneous interventions, the Institute of Diagnostic Radiology in Basel is using the medical assistance system INNOMOTION (TM) developed and manufactured by Innomedic ( Herxheim, Germany). The system does not perform the intervention itself but rather provides the correct insertion angle and depth for the physician who stays in control of the process. After successful completion of the learning curve, the system shall substitute all systems currently used for navigation and puncture assistance. In addition to this, the system shall also be applied in surgery, e. g. trauma surgery. During the current learning curve phase, radiologists and manufacturer are combining their expertise and efforts to continually improve the workflow of planning and executing interventions. The following article describes the execution of an intervention in CT and MRT from the point of view of a registered radiology technician.
