Overview

Robotic patient positioning systems precisely align patients within the MRI bore to reduce setup time and improve reproducibility. These systems can reduce repeat scans caused by mispositioning and help standardize protocols across technologists. Integration with scanner workflows enables automated table moves and coil placement guidance.

Technical Design

Robotic positioning devices use nonmagnetic materials and MRI compatible actuators to operate safely in the magnetic environment. Positioning algorithms incorporate patient anatomy and coil geometry to optimize signal to noise ratio and field of view. Safety interlocks and motion limits prevent collisions and ensure patient comfort.

Clinical Impact

Improved positioning reduces motion artifacts and can shorten exam times which benefits pediatric and claustrophobic patients. Consistent coil placement supports quantitative mapping and multicenter harmonization of protocols. Workflow gains free technologist time for patient care and quality assurance tasks.

Implementation Considerations

MRI compatible robotics require rigorous testing and vendor collaboration for certification and integration. Staff training and protocol validation are necessary to realize throughput and quality benefits. Institutions should evaluate return on investment based on exam volume and complexity.
