The Quality Control (QC) procedure at the Spinoza centre is composed of a weekly and monthly protocol consisting various tests and checks. The QC is usually performed by the scan-assistants of the Spinoza centre, supervised by Tinka and Steven. All relevant data is saved into an excel-file. Below, both procedures are summarized.

Weekly quality control procedure

Scans:

  • Philips Intelligent Quality Test (PIQT): quality check of spatial stability (uses 1 channel headcoil and Philips PQT phantom).
  • BOLD-fMRI (EPI) and DTI-test using the AGAR-phantom: quality check of temporal stability (uses 32 channel headcoil)
  • Spurious test: quality check of homogeneity of static magnetic field.
  • QPI: check for spikes.


Check scanner computer:

  • Virus scan (monthly) and updates (weekly)


Check stimulus-set up in scanner room:

  • Set-up projection screen, beamer, and projected image
  • Response boxes
  • GSR/Eyetracker batteries


Check stimulus-computer:

  • Virus scan and update
  • Windows updates
  • Volume settings, headphone sound quality, Presentation licence
  • Trigger counter (during EPI-scan of the AGAR phantom) to check whether pulses are sent to the stimulus computer.


Check, cubicle computers (incl. NPO) and Mock scanner

  • Presentation license
  • Virus scan and update
  • Windows update
  • Mock scanner: check projection screen/image, headphones (and audio settings), response-boxes


Check, other:

  • Helium level
  • Temperature
  • Back-up ProefpersonenRegistratie and Quality Control log (excel-sheets)
  • Amount of screening-forms, information brochures, and "Toestemmingsverklaringen"

Monthly Quality Control procedure
