  • IMAGE (DATA) ACQUISITION TIME

  • The time required to gather a complete set of image data. The total time for performing a scan must take into consideration the additional image reconstruction time when determining how quickly the image(s) may be viewed.

  • IMAGE RECONSTRUCTION

  • The mathematical process of converting the composite signals obtained during the data acquisition phase into an image.

  • INHOMOGENEITY

  • Lack of homogeneity or uniformity in the main magnetic field.

  • INVERSION RECOVERY (IR)

  • An imaging sequence that involves successive 180 and 90 pulses, after which a heavily T1-weighted signal is obtained. The inversion recovery sequence is specified in terms of three parameters, inversion time (TI), repetition time (TR) and echo time (TE).

  • INVERSION TIME (TI)

  • The time period between the 180 inversion pulse and the 90 excitation pulse in an Inversion Recovery pulse sequence. ISOTOPE - Atomic nuclei that contain the same number of protons, but differ in the number of neutrons in the nucleus of the atom for the element concerned. K-SPACE - a data acquisition matrix containing raw image data prior to image processing. In 2DFT, a line of data corresponds to the digitized NMR signal at a particular phase-encoding level.
