2. Safety of magnetic resonance imaging - Wikipedia

   en.wikipedia.org/wiki/Safety_of_magnetic...

   MR-conditional devices are those that may contain magnetic, electrically conductive, or RF-reactive components that are safe for MRI, provided the conditions are observed. Learn about the types of implants, the risks of heating, projectile, and other effects of MRI, and the certification of MRI professionals.

3. Prism correction - Wikipedia

   en.wikipedia.org/wiki/Prism_correction

   Prentice's rule is a formula to calculate the amount of prism correction in a lens based on decentration and lens power. It can be used for prescribing, tolerance control, or determining unprescribed prism in eyeglasses.

4. Magnetic resonance imaging - Wikipedia

   en.wikipedia.org/wiki/Magnetic_resonance_imaging

   MRI is a medical imaging technique that uses strong magnetic fields, radio waves and nuclear magnetic resonance to create images of the body. MRI does not involve X-rays or ionizing radiation and can provide better contrast for soft tissues than CT or PET scans.

   Doctors are warning patients not to wear spandex clothing when coming in for a magnetic resonance imaging (MRI) procedure. Fabrics that use spandex often have metallic threads that could react ...

6. Prism (optics) - Wikipedia

   en.wikipedia.org/wiki/Prism_(optics)

   Learn about the different types of optical prisms, such as dispersive, reflective, beam-splitting and polarizing prisms, and how they refract, reflect or split light. Find out how prisms are made of transparent materials like glass, acrylic or fluorite, and how they can create spectra, images or polarizations.

   An incident of a wheelchair being flung into an MRI machine, narrowly missing the patient in the room, is raising concerns among safety advocates. Freak accident in Mountain View exposes MRI ...

8. Prism cover test - Wikipedia

   en.wikipedia.org/wiki/Prism_Cover_Test

   The prism cover test (PCT) is an objective method to measure ocular misalignment or deviation of the eye. It involves using prism bars, occluder, and targets to neutralise the deviation and record the angle and base of the prism.
