Although the method has good long-term stability and precision, consistent performance was further ensured by means of a daily quality control scan using a known standard (the manufacturer's phantom).
Responsibilities can include generating imaging guidance documents, managing quality assurance steps, setting up mechanisms to transfer scans to a central location, performing quality control on scans received and the organisation of independent radiological review and/or image analysis.
The long-term stability of the MR system was monitored by weekly quality control (QC) scans during one year.
The automation simplifies standardization and quality control between scans, and is expected to lead to more accurate quantification of the relevant tissues of interest when the system is transported to other sites.
The software package RiSCAN PRO enables an operator to acquire, view and process 3D data as it is acquired, increasing the level of quality control on scan data [50].
Fast tools like sequence statistics, file conversion, quality control, rRNA-scan and ORF calling use only one CPU core; clustering tools use 4 cores in parallel; other relatively time-consuming jobs use up to 40 cores.
Other strengths are centralised reading, including quality control of the scans at the same time as allowing some variation in scanning variables.
Qualitative analysis is often used to determine whether or not a particular feature appears or is absent in tests, in quality control procedures, identification scans, go/no go measurements and many other fields.
In this study, we established quality control by removing scans with insufficient signal strength.
