An investigation of using log- file analysis for automated patient- specific quality assurance in MRgRT
Every Fraction of Every Treatment
Automatic RTPlan Generation
Scripted automatic recalculation with your own TPS
Linear accelerators generate log files which correspond to a copy of the irradiation parameters. LinacView automatically analyzes these log files in real time and in the background by comparing them to the planned treatment described by the DICOM RTplan file associated with the beams, for every session and every patient.
Passively monitor all of your treatment machines for plan delivery accuracy

Powerful Analysis and Easy Installation
LinacView Introduction Video
LinacView is a powerful and versatile tool for logfile analysis. We use the results produced by this software for various applications such as: daily checking of a reference VMAT arc performed on each of our LINACs (for example, to detect when either gantry chain adjustment or leaf motor replacement is required), to investigate a diminished performance in our pre-treatment patient QA, to monitor LINAC performance during each fraction delivered to every one of our patients, to compare, in terms of DVH, the planned treatment and the “delivered” treatment recalculated on our TPS with an RT-plan file exported from LinacView which contains all log file data. For the last use mentioned, we greatly appreciate carrying out these comparisons on our TPS rather than on another TPS. Moreover, I believe that LinacView is a tool which fosters cooperation between manufacturers, medical physics and biomedical engineering departments.
LinacView is a great tool to indicate systematic errors, especially when the MLC or jaw position did not align well for several patients. I was able to use this tool to communicate with field service engineers and make a correction for our Linac. I am pleased with the performance of LinacView.
We routinely rely on LinacView in our medical physics department to follow-up and record the correct application of each treatment with every patient. In addition to patient QA, we also depend on LinacView to verify machine QA. Evaluating the logfiles with this software ensures us that the linac is operating correctly and that the data transfer to the linac has functioned properly. LinacView provides substantial benefits in terms of patient care, as deviations from planned treatment can be rapidly detected by means of this valuable cross-check.
