Abstract
The focal spots of x-ray tubes used for diagnostic radiology are currently receiv-ing a great deal of attention. While researching the history of focal spot specifications, I was surprised to find the following statement under a dateline of September 17, 1 942 (Ref. 1 ): "The subject of focal spots seems to be receiving an undue amount of discussion these days. Some of the discussion is not based on fact and we think some fundamental principles might be helpful. "
