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

Will be uploaded soon.

+* Amount of screening-forms, information brochures, and "Toestemmingsverklaringen"
-When new epquipment is installed or something is changed in the MRI enviroment a spurious test should be performed. This can be done from service mode.
+|}
-!! Crucial, make sure the headcoil is not connected to the system
-Enter service mode.
+== Monthly Quality Control procedure ==
-Go, in the acquisition enviroment to:
-System --> Advanced Tools --> Scan Utilities.
-Select the Scan Utilities in the pane on the left hand side.
-Select 1 (enter service mode)
-Select 2 (Batch Interpreter)
-Select 15 (spurious_t30_180hz_qbc)
-Select proceed
-The spurious test now starts and will last for approximatly 4 minutes. After this a new subject has been created in the exam list called 'spur T30 180Hz/px'. Select New exam and open the 'subject'. Use the + sign to inspect the four images that have been created. That should be nice and homogenous as in the figure below on the right hand side and not contain no lines as in the figure below on the left hand side.
