  • spatially
  • The spatially encoded NMR signal is Fourier transformed into a peak, it is then converted into a gray scale image based on the intensity of the resultant peak. (springer.com)
  • strong magnetic
  • You'll also be asked questions to make sure your child doesn't have any internal metal clips from previous surgery or anything else that might cause a problem near a strong magnetic field. (kidshealth.org)
  • The strong magnetic fields created during an MRI can interfere with certain implants, particularly pacemakers . (daviddarling.info)
  • structures
  • the use of electromagnetic radiation to produce images of internal structures of the human body for the purpose of accurate diagnosis. (britannica.com)
  • artefacts
  • An examiner with experience and knowledge of both fetal development and common artefacts from postmortem MR images is essential to ensure the accurate interpretation of the information obtained. (springer.com)
  • cross-sectional
  • The computer performs millions of calculations, resulting in clear, cross-sectional black-and-white images of the body. (kidshealth.org)
  • Magnetic coils in the MRI machine detect these signals and a computer changes them into a cross-sectional or three-dimensional image based on the strength of signal produced by different types of tissue. (daviddarling.info)
  • signals
  • These signals are converted into an image, and during a single session a doctor collects a series of images, often from several different angles. (britannica.com)
  • blood
  • Differences in magnetic properties between arterial (oxygen-rich) and venous (oxygen-poor) blood provided this link. (wikipedia.org)
  • This difference leads to an improved MR signal since the diamagnetic blood interferes with the magnetic MR signal less. (wikipedia.org)
  • radio
  • These devices help send and receive the radio waves, and improve the quality of the images. (daviddarling.info)
  • this arrangement improves image quality by increasing radio signal strength, since the coil is located close to the tissue being examined. (britannica.com)
  • area
  • Monitor patient safety and comfort, and view images of area being scanned to ensure quality of pictures. (bls.gov)
  • These images can be converted into three-dimensional (3-D) pictures of the scanned area. (kidshealth.org)
  • development
  • However, this opportunity has yet to be fully realized, largely because the development of reliable, valid, and efficient means of quantifying all the information contained within the digital display has lagged far behind the ability to acquire these images. (springer.com)
