1911H. Bauer in Arch. Roentgen Ray XV. 308 Whether this Roentgen Qualimeter, as we may call it, has all the requisites for the standard measure of hardness so much sought for by every Roentgenologist is a question which I must leave for others. 1915R. Knox Radiography 58 It is here that the qualimeter is particularly useful, since different degrees of hardness are required for the production of good pictures of various parts of the body. 1926P. K. Bowes X-Ray Apparatus x. 96 This qualimeter can only be used with any degree of success with one installation, using the same X-ray tube all the time, and never altering the rate of interruptions. |
