Minutes for UCL Proton Beam Therapy Group Meetings, 18th February

Present

Joe Bateman, Sonia Escribano, Simon Jolly


Simon Jolly

  • Chase up Harry about scintillator sheets
  • Chase up Tony about UCLH CMOS data for 3x3 and 5x5 fields
  • Electronics will be received by 20/2
  • Sonia and Joe to consider options for normalisation of QuARC signal to be in terms of Gy or MU
  • Aiming for beam tests - UCLH for week 5/5, Trento for week 12/5


Sonia Escribano

  • Average.csv file that writes raw data to decimal format, separated into two for dual readout
  • Checked that data and errors from average.csv and average_dual.csv are identical and work on gui
  • Will need to generate two calibrated file in real time
    • Need to check reading direction of fpga so knows which way the calibration coefficients need to be applied
  • Created separate DAQ_dual and gui that shows both Bragg peaks
  • Calibration performed for post processing
    • Need to create two separate files and calibrate independently
    • Currently run split_file.cpp works from terminal and generates two files but files not generated when run from GUI
    • Alternative option to generate two separated files during acquisition directly
  • Scintillators should be ready from John and Wayne in 1.5 months ? Will take longest
  • Assembly by mid-april?
  • Joe chase up photodiodes order
  • Matt shall be testing rev e and mod firmware with new electronics next week
  • Windows + patch panel will take around a couple of weeks


Joe Bateman

  • For QuADProBe reconstruction adjusting energy by constant offset since QuARC seems to be measuring ~5.5 MeV less than DICOM
  • For paper reconstructions should run simulations using:
    • All DICOM params
    • All QuADProBe params (1 using CMOS intensity, another using QuARC intensity)
    • QuADProBe params, DICOM intensity
    • Just QuARC energy
  • Had call with Sam on Monday to discuss transmission calorimeter data - can try to use it to scale to actual dose, although TC data is in K but has been correlated with prescribed dose
  • Attempted to duplicate QuARC G4 simulation in TOPAS but not so successful so will continue using the G4 version
