MRI phantom, dissolution sample and method for temperature measurement in an MRI phantom

摘要

The invention relates to an MRT phantom (30) for determining the measurement quality of an MRI system, comprising a three-dimensional fluid-filled body for introduction into a measuring range of the MRI system, wherein at least one dissolution sample (10, 20) is positioned in the body a plurality of well-defined structures of different sizes and / or different ADC values, which allow a determination of the quality of measurement of the MR system at the position of the dissolution sample (10, 20) in the body of the phantom (30). Furthermore, the invention relates to a dissolution sample (10, 20) for use in an MRI phantom, and to a method for temperature measurement in an MRI phantom (30), in particular in a dissolution sample (10, 20) of an MRI phantom (30).
