Data Content

• All of this has been done for plain film examinations so far. • From 2007 to 2009, we obtained 730,000 examination records from 5 hospitals

• 47,750 of these records are CT examinations from 6 scanners @ 4 hospital sites

Can any of these processes be applied to CT?

Data Acquisition

DIRECT • Contact RIS manager (via Radiology) • Ask nicely (biscuits work) for specific fields (next slide) • A ‘stat’ is produced in either XLS, CSV or XML format

CENTRALLY • Country divided into Regions • Regions divided into Clusters • Find friendly RIS manager (upgrade to chocolate) • They can obtain data from whole cluster (with same RIS?)
