Spatial Gradient Magnetic Field Safety - Video Lesson

Hey everybody. Welcome back to our MRI safety course. In this lesson, we will review static magnetic field safety including spatial gradient magnetic field and lens forces as well as mitigating risk for patients and medical personnel. Let's get started. In the complex environment of MRI, patient and staff safety depend on a comprehensive understanding of the magnetic fields that make this technology possible. MRI systems rely on several magnetic fields to acquire detailed anatomical images. First, the main static magnetic field also known as b sub zero is the powerful uniform magnetic field generated by the MRI scanner. In clinical settings, it is typically one point five Tesla or three point zero Tesla. B sub zero is constant and extends well beyond the bore remaining active even when the superconductive scanner is not imaging. The flux lines outside the bore of the magnet running north to south
