description | This study aims to introduce IViST (In Vivo Source Tracking), a novel
multi-sensors dosimetry platform for real-time treatment monitoring in HDR
brachytherapy. IViST is a platform that comprises 3 parts: 1) an optimized and
characterized multi-point plastic scintillator dosimeter (3 points mPSD; using
BCF-60, BCF-12, and BCF-10 scintillators), 2) a compact assembly of
photomultiplier tubes (PMTs) coupled to dichroic mirrors and filters for
high-sensitivity scintillation light collection, and 3) a Python-based
graphical user interface used for system management and signal processing.
IViST can simultaneously measure dose, triangulate source position, and measure
dwell time. By making 100 000 measurements/s, IViST samples enough data to
quickly perform key QA/QC tasks such as identifying wrong individual dwell time
or interchanged transfer tubes. By using 3 co-linear sensors and planned
information for an implant geometry (from DICOM RT), the platform can also
triangulate source position in real-time. A clinical trial is presently
on-going using the IViST system. |
