Earl Wood
Earl Howard Wood (January 1, 1912 – March 18, 2009) was an American cardiopulmonary physiologist who helped invent the G-suit, brought heart catheterization into a clinical reality and introduced dynamic volumetric computed tomography for the study of the heart and lungs. Career G-suit Shortly after receiving an Doctor of Medicine, M.D. and PhD in physiology from the University of Minnesota medical school under the mentorship of Professor Maurice B. Visscher, MD, Wood became a key member of a team, working in a laboratory at the Mayo Clinic, tasked with helping military pilots and flight crew survive and function in high G-force environments. Based upon extensive physiologic testing via use of the human centrifuge installed at the Mayo Clinic, it was determined that blackout and then unconsciousness was caused by reduction of blood flow to the eyes first and then the brain. The solutions the team arrived at were the M-1 breath hold maneuver and the G-suit. The M-1 maneuver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Paperclip
The Operation Paperclip was a secret United States intelligence program in which more than 1,600 German scientists, engineers, and technicians were taken from former Nazi Germany to the US for government employment after the end of World War II in Europe, between 1945 and 1959; several were confirmed to be former members of the Nazi Party, including the SS or the Sturmabteilung, SA. The effort began in earnest in 1945, as the Allies advanced into Germany and discovered a wealth of scientific talent and advanced research that had contributed to Germany's wartime technological advancements. The US Joint Chiefs of Staff officially established Operation Overcast (operations "Overcast" and "Paperclip" were related, and the terms are often used interchangeably) on July 20, 1945, with the dual aims of leveraging German expertise for the ongoing war effort against Japan and to bolster US postwar military research. The operation, conducted by the Joint Intelligence Objectives Agency (JI ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computed Tomography
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry to measure X-ray attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is contraindicated. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, it can also be used to form images of non-living objects. The 1979 N ...

Girl Scouts Of The USA
Girl Scouts of the United States of America (GSUSA), commonly referred to as Girl Scouts, is a youth organization for girls in the United States and American girls living abroad. It was founded by Juliette Gordon Low in 1912, a year after she had met Robert Baden-Powell, 1st Baron Baden-Powell, Robert Baden-Powell, the founder of Scouting (formerly Boy Scouts). The stated mission of Girl Scouts is to "[build] girls of courage, confidence, and character, who make the world a better place" through activities involving camping, community service, and practical skills such as first aid. Members can earn badges by completing certain tasks and mastering skills. More senior members may be eligible for awards, such as the Bronze Award (Girl Scouts of the USA), Bronze, Silver Award (Girl Scouts of the USA), Silver, and Gold Award (Girl Scouts of the USA), Gold Awards. Membership is organized according to grade level, with activities designed for each level. The organization is a member ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medal Of Freedom (1945)
The Medal of Freedom was a decoration established by President Harry S. Truman to honor civilians whose actions aided in the war efforts of the United States and its allies during and beyond World War II. It was intended to be awarded by the secretary of state, the secretary of war, or the secretary of the navy, but presidents Dwight D. Eisenhower and John F. Kennedy also authorized awards. The first woman and American citizen to receive it was Anna M. Rosenberg by Robert P. Patterson Robert Porter Patterson Sr. (February 12, 1891 – January 22, 1952) was an American judge who served as United States Under Secretary of War, Under Secretary of War under President Franklin D.

Fluoroscopy
Fluoroscopy (), informally referred to as "fluoro", is an imaging technique that uses X-rays to obtain real-time moving images of the interior of an object. In its primary application of medical imaging, a fluoroscope () allows a surgeon to see the internal anatomy, structure and physiology, function of a patient, so that the pumping action of the heart or the motion of swallowing, for example, can be watched. This is useful for both medical diagnosis, diagnosis and therapy and occurs in general radiology, interventional radiology, and image-guided surgery. In its simplest form, a fluoroscope consists of an X-ray generator, X-ray source and a fluorescence, fluorescent screen, between which a patient is placed. However, since the 1950s most fluoroscopes have included X-ray image intensifiers and cameras as well, to improve the image's visibility and make it available on a remote display screen. For many decades, fluoroscopy tended to produce live pictures that were not recorded, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angiography
Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. Modern angiography is performed by injecting a radio-opaque contrast agent into the blood vessel and imaging using X-ray based techniques such as fluoroscopy. With time-of-flight (TOF) magnetic resonance it is no longer necessary to use a contrast. The word itself comes from the Greek words ἀνγεῖον ''angeion'' 'vessel' and γράφειν ''graphein'' 'to write, record'. The film or image of the blood vessels is called an ''angiograph'', or more commonly an ''angiogram''. Though the word can describe both an arteriogram and a venogram, in everyday usage the terms angiogram and arteriogram are often used synonymously, whereas the term venogram is used more precisely. The term angiography has been applied to radionuclide angiography and newer vascular ima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
