1920s radiology

Seymour Cochrane Shanks

Seymour Cochrane Shanks reviewed radiology in the 1920s (Cochrane Shanks BJR 1973; 46(550):  766-767). There was a considerable degree of sophistication to radiology in the 1920s. The early gas X-ray tubes were replaced with the new hot-cathode vacuum Coolidge tubes which were much more predictable in their output. Radiography was becoming less of an art and more of a science. The radiation protection of the tubes improved dramatically with the use of self-protected tubes however there was still an element of electrical danger before the shockproof apparatus was introduced in the 1930s.

Robert Knox died on the 21st September 1928 and he is mourned in the British Journal of Radiology (BJR 1928; 1(10): 344-348). Knox “worked unceasingly for British radiology” and we owe him a debt of gratitude. He played a leading role in the formation of the British Institute of Radiology and was the author of influential books on therapy and diagnosis.
