Comparative optic and dosimetric characterization of the HYPERSCINT scintillation dosimetry research platform for multipoint applications

This study introduces the HYPERSCINT research platform, first commercially available scintillation dosimetry platform capable of multi-point through hyperspectral approach. Optic and dosimetric performances system were investigated comparison with another solution, Ocean Optics QE65Pro spectrometer. The optical characterization was accomplished by measuring linearity signal as a function integration time, photon detection efficiency spectral resolution for both systems. Dosimetric then evaluated 3-point plastic scintillator detector (mPSD) in terms to noise ratio (SNR) background (SBR) associated each scintillator. latter subsequently compared those found literature Exradin W1, single-point detector. Finally, various beam measurements realized evaluate its ability perform clinical dosimetry. Both systems be comparable intensity. Although possesses higher resolution, efficency is up 1000 time greater. shows that also offers better SNR SBR, surpassing even W1 PSD. While doses ranging from 1 cGy 600 accurately measured within 2.1% predicted dose using coupled mPSD, optics spectrometer discrepencies 86% under 50cGy. Similarly, depth dose, full width at half maximum region profile output factors all 2.3% exhibit an average difference 0.5%, 1.6% 0.6%, respectively.
