SmartPhantom meeting: Wednesday 2nd August 2019, 13:00 BST, 14:00 CEST

Notes:

Present: KL, HTL, AK, LC, MP

  1. Welcome/introduction: KL
    • We introduced ourselves: Liam, design engineer (RAL); HTL, AK, KL physicists (Imperial); Monika, responsible for dosimetry/instrumentation (TUW).
  1. Status of SmartPhantom preparation: HTL
    • Slides. Points noted:
      • In preparation for the exposure we may need to plan a CT of the SmartPhantom for the TPS calculation.
      • In the measurement plan we need to include:
        • An exposure with the SmartPhantom and an ionisation chamber to cross calibrate the energy reconstruction; and
        • An exposure with the SmartPhantom and the "Linx camera" to cross calibrate he position reconstruction.
  1. Water phantom and preparation for beam at MedAustron: MP
  • The phantom that is being planned for the measurements is the same as that used as the basis for the SmartPhantom design.
  1. Discussion and next steps
    • Ethernet is available in the research room;
    • MP: Will check the beam energy spread, perhaps as a function of energy.
    • There is a trigger signal in the research room. It seems likely that this is the synchrotron cycle-start signal. MP: agreed to check the definition of the trigger signal.
    • The electronics should go to the side of the water phantom, not behind. MP: will make a sketch of the space available for the water phantom, the SmartPhantom, and its electronics. The couch will be included in the sketch.
    • We need to develop an installation, commissioning, calibration, and exposure plan. Agreed to work on this together.
    • It is permitted to use stainless steel studding in the station supports.
    • We agreed to consider the construction of a model to allow an early fit-check.
    • What is the minimum distance from the flask that we can put the detector? We have a flask at Imperial and can begin to study this.
    • We agreed that MP: would make a sketch ('technical drawing') of the water phantom. HT: will circulate and post the water phantom specs.
    • We discussed the requirement to position the SmartPhantom accurately and to maintain its position. LC: will consider the positioning mechanism.
  1. DONM
    • Standing invitation to MP to join SmartPhantom meetings. Contact with MP can be maintained by email and phone. Specific meetings can be arranged as required.

Summary of actions:

  • MP: will check the beam energy spread, perhaps as a function of energy.
  • MP: will check the definition of the trigger signal.
  • MP: will make a sketch of the space available for the water phantom, the SmartPhantom, and its electronics. The couch will be included in the sketch.
  • MP: will make a sketch ('technical drawing') of the water phantom.
  • HT: will circulate and post the water phantom specs.
  • LC: will consider the positioning mechanism.
