Mobius Medical was founded in 2010 with a mission to provide innovative software for modern radiation oncology practices. All Mobius Medical Systems' software is designed to save clinicians time and effort when performing important and necessary quality assurance while providing them with the data they need to make intelligent, informed decisions about planning system and treatment machine performance. Our products include DoseLab, the most widely used TG-142 software and Mobius3D, the first 3D solution for patient plan and delivery QA. Mobius3D provides a three-dimensional secondary check of treatment plans created on commercial treatment planning systems using an independently developed collapsed cone convolution superposition algorithm and the patient's planning CT. The MobiusFX module in Mobius3D utilizes treatment log files from Varian and Elekta linear accelerators to perform patient specific QA for IMRT and VMAT treatments in as little as one minute.
