I dare say we are witnessing the beginning of a new era of the Inter American College of Radiology, based on the participation of all country members, which have been reorganizing their societies, and on the impact of the technologic development of our specialty in benefit of the wellbeing of our patients. Radiology is nowadays considered one of the specialties with the highest importance, not only due to this level of participation as an incentive, but also due to the addition of new generations of different postgraduates in the region that integrate in a physical and virtual way within the CIR activities.

If we add the acknowledgement of our institution on the part of the main international societies, as well as those world organizations related to ionizing radiation, diagnostic imaging of radiologic protection and safety, together with the technological platform of electronic training, make of the Inter American College of Radiology one of the main associations of radiology and diagnostic imaging in the world, with a history that dates back to half a century ago. Throughout this time we have been working with a different perspective and a different scenario, just as we did at the very beginning.

No doubt, we are making our way through, with a vision and context of future. That’s why we should feel proud of our institution and we should feel invited to each of the activities that it proposes.

We would like to extend this invitation even farther and in a dynamic way through all our communication portals, and highlight the work done by the different boards of all Societies, Associations and Federations that are part of this College. They are the true founding of our constant change and innovation that match with the technology that has always been characteristic since the beginning of our specialty.

Ultrasound Quarterly is the official organ of the Society of Radiologists in Ultrasound (SRU) and it covers the latest and most sophisticated techniques, as well as the deep analysis of important developments in this dynamic field. The magazine publishes its own research and reviews a wide variety of topics, including transvaginal Ultrasonography, detection of fetal anomalies, fluid image with color Doppler, pediatrics Ultrasonography and mammary sonography, and more.

We invite the whole radiologic community of Latin America and Spain to send their manuscripts to:

GO RAD is a new global outreach program developed by the International Society of Radiology. Its purpose is to achieve advanced radiology education throughout a global radiology community by adding current and practical radiology literature with content that is targeted and addressed to the developing nations and populations with scarce resources.

We hope that you make the most of this program in order to improve everybody’s health and well-being.

The History Corner

William David COOLIDGE

He was an American engineer and physicist (Hudson, 1873 – Schenectady, 1975) who was known for the creation of the X rays tube that carries his name, and that in 1913 represented a revolution in the field of radiology and medicine.

He studied in the Massachusetts Technology Institute of Cambridge and in the University of Leipzig. He was professor of said Institute and in 1905 he obtained a position in the laboratory of General Electric. This position assured him the fact that he could dedicate all the necessary time to do research on conductivity measurement, which was his field of interest in the Technology Institute.

Here he worked on the substitution of the weak carbon filaments with the tungsten light bulb, which was commercialized by the corporation. The same was done later with the X-ray Coolidge tube. He developed a form of flexible tungsten which he called ductile tungsten. The tungsten filaments extended quickly to the use of light bulbs, radio bulbs and other devices. With these, light bulbs lasted much longer.

The tungsten was also the main metal in the development of the X-rays tube. Coolidge implemented a block of this metal as anode in a cathode rays tube in order to produce X- rays. This invention allowed the use of X-rays beyond the Physics laboratory and found a true application in the industry field (in the area of quality control), in Medicine (with diagnostic purposes and for cancer treatment) and in Deontology.

In 1917, during World War I, he developed a mobile generator of X-rays and in 1924 he presented a rays tube immersed in oil that could be manipulated without any risk. Four years later, he contributed even more through the explanation of the cathode cooling effect, which limits the voltage used in a given tube. In 1932 he became director of the General Electric Research Laboratory and in 1940 he was appointed vice president and research director of said company. Throughout World War II he studied the value of uranium for military use and he was involved in the development of the atomic bomb. Throughout his life he patented 83 inventions. Among the awards he received, we should point out the Edison Medal, the Faraday Medal of the Institution of Electric Engineers of England, and the Duddell Medal of the Physical Society of England.
