Magnetic Resonance Imaging (MRI) is the most common systems used in acquiring detailed anatomical information in medical imaging. The key feature of the imaging technologies is their ability to provide detailed information about the anatomical structure and abnormalities. MRI images are obtained by varying the number and sequence of pulsed radio frequency field in order to take advantage of magnetic relaxation properties of hard and soft tissues. Specifically a strong magnetic field is generated to cause atoms inside the body to become aligned. After alignment, a radio wave is issued to activate the atoms. Once the radio signal is turned off, the atoms give off a small characteristic signal. Those signals are then measured with a sensitive antenna called an MRI coil. This process is repeated many times until enough measurements are detected to create a series of detailed images. MRI does not use any ionizing radiation, and can create images of almost any body part oriented in any direction. Figure 8.1 shows a MRI example of a head.
