Preface iii
Preface
Intended Use
Model 1178 MapCHECK 3 is a two-dimensional (2D) radiotherapy beam dosimetry QA system
intended for the measurement of radiation dose distributions for the purpose of comparison with
a simulated dose distribution in the same phantom geometry as calculated by the treatment
planning system (TPS).
CAUTION: Federal law restricts this device to sale by or on the order of a qualified
radiation therapy professional, such as a medical dosimetrist, medical physicist, or
radiation oncologist for use in radiation oncology.
Description
The MapCHECK®3 device contains an array of 1,527 SunPoint®2 Diode Detectors that measure
ionizing radiation to simulate patient structure during delivery of a treatment plan dose. The SNC
Patient™ software displays the MapCHECK 3 measurement and compares the results against the
imported treatment plan.
For detailed SNC Patient software instructions, see the SNC Patient online Help or the SNC Patient
Software Reference Guide, available on the Sun Nuclear Support website (see Support Website
on page 15).
