Leopold Freund
Leopold Freund (April 5, 1868 – January 7, 1943) was an Austrian-Jewish radiologist, considered the founder of medical radiology and radiotherapy. Leopold Freund was born in Miskovice in Central Bohemia, then part of the Austro-Hungarian empire, now part of the Czech Republic. He died in Brussels in 1943. Freund was a professor of radiology at the Medical University of Vienna and is considered the founder of medical radiology and radiotherapy. He is the first physician known to have used ionizing radiation for therapeutic purposes. In 1896, a year after the discovery of X-rays by Wilhelm Röntgen and in the same year that Antoine Henri Becquerel discovered radioactivity, Freund successfully treated a five-year-old patient in Vienna suffering from hairy moles covering her whole back. The case was published by the girl's local physician, Schiff, in 1901. In 1903, he published the first textbook on radiation therapy.''Grundriß der gesamten Radiotherapie für praktische Ärzte'', ...

Becquerel
The becquerel (; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. For applications relating to human health this is a small quantity, and SI multiples of the unit are commonly used. The becquerel is named after Henri Becquerel, who shared a Nobel Prize in Physics with Pierre and Marie Skłodowska Curie in 1903 for their work in discovering radioactivity. Definition 1 Bq = 1 s−1 A special name was introduced for the reciprocal second (s−1) to represent radioactivity to avoid potentially dangerous mistakes with prefixes. For example, 1 µs−1 would mean 106 disintegrations per second: 1·(10−6 s)−1 = 106 s−1, whereas 1 µBq would mean 1 disintegration per 1 million seconds. Other names considered were hertz (Hz), a special name already in use for the reciprocal second, and Fourier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Austrian Jews
The history of the Jews in Austria probably begins with the Jewish diaspora, exodus of Jews from History of ancient Israel and Judah#Roman occupation, Judea under Roman occupation. Over the course of many centuries, the political status of the community rose and fell many times: during certain periods, the Jewish community prospered and enjoyed political equality, and during other periods it suffered pogroms, deportations to concentration camps and mass murder, and antisemitism. The Holocaust drastically reduced the Jewish community in Austria and only 8,140 Jews remained in Austria according to the 2001 census, though other estimates place the current figure at 9,000, 15,000, or 20,000 people, if accounting for those of mixed descent. Antiquity Jews have been in Austria since at least the 3rd century CE. In 2008 a team of archeologists discovered a third-century CE amulet in the form of a gold scroll with the words of the Jewish prayer Shema Yisrael (Hear, O Israel! The Lord ...

Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe. On 30 January 1933, Hitler was appointed chancellor of Germany, the head of gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melanocytic Nevus
A melanocytic nevus (also known as nevocytic nevus, nevus-cell nevus and commonly as a mole) is a type of melanocytic tumor that contains nevus cells. Some sources equate the term mole with "melanocytic nevus", but there are also sources that equate the term mole with any nevus form. The majority of moles appear during the first two decades of a person's life, with about one in every 100 babies being born with moles. Acquired moles are a form of benign neoplasm, while congenital moles, or congenital nevi, are considered a minor malformation or hamartoma and may be at a higher risk for melanoma. A mole can be either subdermal (under the skin) or a pigmented growth on the skin, formed mostly of a type of cell known as a melanocyte. The high concentration of the body's pigmenting agent, melanin, is responsible for their dark color. Moles are a member of the family of skin lesions known as nevi and can occur in all mammalian species, but have been documented most extensively in humans, ...

Wilhelm Röntgen
Wilhelm Conrad Röntgen (; ; 27 March 184510 February 1923) was a German mechanical engineer and physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the inaugural Nobel Prize in Physics in 1901.Novelize, Robert. ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. 1997. p. 1. In honour of Röntgen's accomplishments, in 2004 the International Union of Pure and Applied Chemistry (IUPAC) named element 111, roentgenium, a radioactive element with multiple unstable isotopes, after him. The unit of measurement roentgen was also named after him. Biographical history Education He was born to Friedrich Conrad Röntgen, a German merchant and cloth manufacturer, and Charlotte Constanze Frowein. At age three his family moved to the Netherlands where his family lived. Röntgen attended high school at Utrecht Technical School in Utrecht, Netherland ...

Radiologist
Radiology ( ) is the medical discipline that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography (which is why its name has a root referring to radiation), but today it includes all imaging modalities, including those that use no electromagnetic radiation (such as ultrasonography and magnetic resonance imaging), as well as others that do, such as computed tomography (CT), fluoroscopy, and nuclear medicine including positron emission tomography (PET). Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above. The modern practice of radiology involves several different healthcare professions working as a team. The radiologist is a medical doctor who has completed the appropriate post-graduate training and interprets medical images, communicates these findings to other physicians by m ...

Medical University Of Vienna
The Medical University of Vienna (German: ''Medizinische Universität Wien'') is a public university located in Vienna, Austria. It is the direct successor to the faculty of medicine at the University of Vienna, founded in 1365 by Rudolf IV, Duke of Austria. As one of the oldest medical schools in the world, it is the oldest in the German-speaking countries, and was the second medical faculty in the Holy Roman Empire, after the Charles University of Prague. The Medical University of Vienna is the largest medical organisation in Austria, as well as one of the top-level research institutions in Europe and provides Europe's largest hospital, the Vienna General Hospital, with all of its medical staff. It consists of 31 university clinics and clinical institutes, and 12 medical-theoretical departments, which perform around 48,000 operations each year. The Vienna General Hospital has about 100,000 patients treated as inpatients and 605,000 treated as outpatients each year. There hav ...
