Final answer:
A patient transfer device or system is used to move patients from a bed to a gurney, particularly when undergoing procedures like an MRI.
Step-by-step explanation:
The device used for patients moving from a bed to a gurney is commonly known as a patient transfer device or patient transfer system. This medical equipment helps safely and efficiently move patients, especially those who are unable to move themselves due to illness, surgery, or other conditions.
In the context of magnetic resonance imaging (MRI), the patient transfer system would ensure a smooth transition into the MRI tunnel on the gurney, utilizing the cylindrical-coil electromagnet that produces the main magnetic field. The transfer process should be handled by trained healthcare professionals to maintain patient safety and comfort during the transition.
