MRPen – 3D Marker Tracking for Percutaneous Interventions
Introduction In percutanous MR-guided interventions passive markers are used to delineate the position or the trajectory of rigid instruments. In particular, for linear instruments such as puncture needles cylindrical markers are favorable, as the instrument can be safely accommodated in their interior. Cylindrical markers can be localized rapidly if their approximate position is known [1]; how...
متن کاملFast and Precise: Real Time MR-guided Prostate Biopsy at 3 Tesla in Animal Experiment
Introduction Since MR-guided interventions require both high image quality and short acquisition times, in clinical routine such procedures are increasingly performed within closed-bore high field MR systems which offer only limited patient access. Safe and precise localization of the instruments is mandatory for any intervention. Recently, an automatic tracking technique has been presented, wh...

متن کاملAccuracy Evaluation of Phase-Only Cross Correlation (POCC) Guidance Sequence for Real-Time 3T MR-Interventions
Introduction MR-guided interventions require a high image quality, short acquisition times and a high precision. In clinical routine such procedures are increasingly performed in closed-bore high field MR systems. Unfortunately, such systems only offer a limited patient access. Recently, an automatic tracking technique has been presented, which uses a passive MR marker for real time needle guid...
متن کامل3D MRI-guided Passive Catheter Tracking and Visualization using HYPR-based Techniques
INTRODUCTION Catheter tracking and visualization require both good spatial and temporal resolution. Achieving simultaneously both high temporal and spatial resolution is extremely difficult with current methods that use Cartesian k-space acquisition employing phase encoding. To date, passive device tracking and visualization techniques have typically been limited to two dimensions [1-2]. This i...
