APPARATUS FOR MAKING OBSERVATIONS BY MEANS OF ROENTGEN OR X RAYS. SPECIFICATION forming part of Letters Patent No. 616,513, dated December 27, 1898. Application filed November 19, 1897. Serial No. 659,139. (No model.) To (6 whom it may concern.-

Nov 17, 2020 · Look again at the data for that device - on page 3; the X-Ray beam emission is spread over a 31' angle. The "focus" in tube type X-Ray imagery system relates to the size of the electron beam impact site in the tube; how small and consistent the source is so it casts a finely detailed shadow through the object.

Polarization of X-rays was first demonstrated by Barkla. He was performing experiments on the secondary X-ray radiation phenomena (C. G. Barkla 1905). He used a block of graphite that scatters the primary X-ray beam from an X-ray tube. The scattered intensity of the X-ray beam was measured in two mutually perpendicular directions.

How is a mammogram taken? Using a low-dose x-ray, the mammogram machine takes a snapshot of the inside of a woman’s breast. The machine holds and compresses the breasts so that images at different angles can be taken. Doctors and nurses examine these snapshots, looking for signs of abnormalities such as lumps, which could be tumors. The results of a mammogram are usually available rather ...
