Medical radiology has now existed for over a century. It all started in 1895 when Wilhelm Röntgen discovered x-rays
Most of the early x-ray work was performed by doctors and the departments were often combined with electro-therapeutic departments. However, from about 1903 lay x-ray operators were appointed as assistants.
The radiographs were initially made onto glass photographic plates; George Eastman introduced film in 1918.
Gradually more and more of these lay x-ray operators were appointed, training courses were set up and the Society of Radiographers was formed in 1920.
Ultrasound started in the 1950s and gained popularity in the 1960s.
Image Intensifier & X-Ray Television
In the 1950s came the development of the image intensifier and x-ray television.
"Real time" Ultrasound
“Real-time” ultrasound machines were introduced in the late 1970s
The principles of CT scanning were invented by Godfrey Hounsfield and the first CT scan was announced in 1972.
Progress for the MRI
Work was progressing on magnetic resonance imaging in the 1970s and the first human image was obtained in Aberdeen in 1977
First MRI body exam
