Parallel quantitative mass imaging with MIMS, using a cochlear field as an example. A schematic representation of the MIMS instrument is shown at the top, with the secondary ions beings selected in parallel by four detectors (T1–T4) which are moved along the focal plane to the appropriate positions for a given mass. The ¹²C^-, ¹³C^-, ¹²C¹⁴N^- and ¹²C¹⁵N^- quantitative mass images recorded by the four detectors are shown below.
