What is it indicated for?
Mobius3D software is used for quality assurance and treatment plan verification in
radiation therapy. It calculates radiation dose three dimensionally in a representation of
a patient or a phantom. The calculation is based on read-in treatment plans that are
initially calculated by a treatment planning system, and may additionally be based on
external measurements of radiation fields from other sources such as linac delivery log
data.
Mobius3D is not a treatment planning system. It is only to be used by trained radiation
oncology personnel as a quality assurance tool.
Indications for use as stated in the FDA summary.
