MUCheck is an independent second-check verification software package designed to validate monitor unit (MU) calculations performed by a primary radiation treatment planning system. Released in 1998, MUCheck is our first second-check software module available to the public. Many other software modules later joined the MUCheck product suite – including IMRT Check, BrachyCheck, CyberKnife Check, Gamma Knife Check, TomoCheck, and VMAT Check.

MUCheck is an excellent tool for basic photon and electron calculations, including forward plans. However, don’t let it’s simple interface fool you. This powerful software contains a variety of tools to allow you to adjust for flash, update calculation points, and make your second-check QA process a breeze! With its extensive list of features, any qualified member of your therapy department can perform calculations quickly and easily.

Please note: The features described below are for our 2D/3D calculation software. We offer additional modules for more advanced or specialized linac-based treatments. Please see IMRT Check and our new VMAT Module for additional information.
