Developments in the legislation that re...

Medicine has been intimately associated with ionising radiation since the discovery of x rays in 1895; the first adverse effects of radiation were observed in persons working in research and on medical staff using x rays. Consequently, in 1925, the first International Congress of Radiology considered the need for a protection committee, which was established at its second congress in Stockholm ...

Radiology education is heavily dependent on visual images, and case-based teaching files comprising medical images can be an important tool for teaching diagnostic radiology. Currently, hardcopy film is being rapidly replaced by digital radiological images in teaching hospitals, and an electronic teaching file (ETF) library would be desirable. Furthermore, a repository of ETFs deployed on the W...
