Download the USER GUIDE (update: 2023-01) for a description of MUST functions and examples (PDF).

This flowchart shows how MUST functions should typically be used:


The theory in MUST has been presented here and there, during IUS short courses and a TUFFC international school, or in some articles (list below). A two-part article that thoroughly describes the theory of the simulator and compares PFIELD and SIMUS with other simulators has been published in Comput Methods Programs Biomed. PFIELD and SIMUS use the linear acoustic far-field and paraxial equations in the Fourier domain.

If you enjoy the MUST toolbox and its simulator SIMUS or SIMUS3, please consider citing the following articles. The MUST function "cite" can help you. Enter "cite" in the MATLAB command window!
