Sep 01,  · In this paper, the discussion focuses on experiments that were designed 1) to determine the uncertainty of x-ray absorption measurements and evaluate the utility of the Poisson estimate and 2) to determine how to properly average data to get a representative view of the specimen's mean relative density and composition variations. In the Dec. 1, edition of The X-ray Century we looked at the investigation which led Dr. Roentgen to write this paper. In the Jan. 1, edition of The X-ray Century we read Prof. Roentgen's first paper describing the new kind of ray. In the Feb. 1, edition of The X-ray Century we watched the word spread around the world. Mar 10,  · TY - JOUR. T1 - Self-calibration of cone-beam CT geometry using 3D-2D image registration.

The standard x-ray examination of the chest consists of a frontal (PA) and lateral view. The frontal view is called a PA view because the patient stands with the anterior chest on the cassette and the back to the x-ray beam. The x-rays first hit the posterior and then the anterior chest before hitting the cassette; thus the name PA.

The cassette is 6 feet from the x-ray tube. The lateral film Author: Michael Boyars. Here is the most comprehensive treatment available on practical temperature measurement methods using radiation thermometry.
