What scientist took x-rays of DNA Crystals that were used by Watson and Crick to measure?
Maurice Wilkins
The CAT scanner, or CT (computed tomography) scanner, was invented by British engineer Godfrey Hounsfield and German physicist Allan Cormack. Their pioneering work in the early 1970s led to the development of the first practical CT scanner, which was introduced in 1971. Hounsfield and Cormack were awarded the Nobel Prize in Physiology or Medicine in 1979 for their contributions to medical imaging.
Do they x-ray your bags when you go on euro star?
ALL luggage entering or leaving the UK is subject to security checks, no matter what mode of transport you use. This includes x-ray searches.
How are gamma rays and X rays similar?
Both gamma rays and X-rays are forms of electromagnetic energy. Also, they are both forms of ionizing radiation. Further, they are found at the very top end (the highest frequencies) of the electromagnetic specturm.
Why does an X-ray beam need to be narrow?
X-ray technicians use colimators to narrow the x-ray beam to:
- lower the dose the patient gets
- lower the effect of scattered radiation
Grid control X-ray tube versus dual X-ray tube?
A Grid Controlled X-ray Tube is a triode in which a third electrode is introduced between the Anode and Cathode. This electrode is normally neutral so the x-ray production can take place. However, one can decide when to cut the exposure by introducing negative charge on this. This will then stop (repel) the electron from reaching the Anode and x-ray production is stopped. Therefore, the elecrode with a negative charge can as a timer or if chrge is given intermittently, it acts as a device to have flouroscopy in pulses.
Can a X-ray detect any stomach problems?
Typically, an x-ray is used to detect skeletal problems, as bones show up well in x-ray imagery. The stomach itself cannot be seen very well with an x-ray, however it is possible that x-ray images be taken of the stomach in order to identify an object inside of it.
okay this guy who wrote up there is wrong! it can show inflammation of the stomach, air bubbles, and it can lead docs to finding out if you have a mass or something but will not show well but it would possibly show an abnormality.
What is the medical term meaning X-rays examination of the bile ducts?
the answer is POCA
Percutaneous Transhepatic Cholangiogram
What is conventional tomography?
Conventional x-ray tomography is an technique to make an x-ray image of a certain "slice" in a persons body in which the slices above and below are blurred. This is different from a conventional x-ray where all slices are stacked on top of eachother.
Nowadays, computed tomography has rendered conventional tomography obsolete.
What is the difference between MRI scanner and chest X-ray machine?
X-rays use what are called X-rays...that was a given but MRIs use magnetic pulses instead of the X-rays. The difference is that the X-rays don't pass through bone (so you see the bone) and the magnetic pulses penetrate the entire flesh but bounce off every cell. This shows what the inside of the person looks like.

- All persons in the control booth must be completely behind the lead barrier
- No image receptors should be in the room except the one in use
The features of the x-ray room and the safety ties in together mostly because the fact that most all of the equipment in the essential x-ray room are used for safety.
Why do the sun's rays feel hotter in the afternoon than in the morning or evening?
because intensity of rays is more in afternoon
What type of college that you have to attend to become an x ray technician?
The following is written by and according to the U.S. Department of Labor and particular to the education and training required for an X-Ray Technician.
Preparation for this profession is offered in hospitals, colleges and universities, and less frequently at vocational-technical institutes. Hospitals employ most radiologic technologists. Employers prefer to hire technologists with formal training.
Education and training. Formal training programs in radiography range in length from 1 to 4 years and lead to a certificate, an associate degree, or a bachelor's degree. Two-year associate degree programs are most prevalent.
Some 1-year certificate programs are available for experienced radiographers or individuals from other health occupations, such as medical technologists and registered nurses, who want to change fields. A bachelor's or master's degree in one of the radiologic technologies is desirable for supervisory, administrative, or teaching positions.
The Joint Review Committee on Education in Radiologic Technology accredits most formal training programs for the field. The committee accredited more than 600 radiography programs in 2007. Admission to radiography programs require, at a minimum, a high school diploma or the equivalent. High school courses in mathematics, physics, chemistry, and biology are helpful. The programs provide both classroom and clinical instruction in anatomy and physiology, patient care procedures, radiation physics, radiation protection, principles of imaging, medical terminology, positioning of patients, medical ethics, radiobiology, and pathology.
Licensure. Federal legislation protects the public from the hazards of unnecessary exposure to medical and dental radiation by ensuring that operators of radiologic equipment are properly trained. Under this legislation, the Federal Government sets voluntary standards that the States may use for accrediting training programs and licensing individuals who engage in medical or dental radiography. In 2007, 40 states required licensure for practicing radiologic technologists and technicians.
Certification and other qualifications. The American Registry of Radiologic Technologists (ARRT) offers voluntary certification for radiologic technologists. In addition, 35 States use ARRT-administered exams for State licensing purposes. To be eligible for certification, technologists generally must graduate from an accredited program and pass an examination. Many employers prefer to hire certified radiographers. To be recertified, radiographers must complete 24 hours of continuing education every 2 years.
Radiologic technologists should be sensitive to patients' physical and psychological needs. They must pay attention to detail, follow instructions, and work as part of a team. In addition, operating complicated equipment requires mechanical ability and manual dexterity.
Advancement. With experience and additional training, staff technologists may become specialists, performing CT scanning, MR, and angiography, a procedure during which blood vessels are x rayed to find clots. Technologists also may advance, with additional education and certification, to become a radiologist assistant.
Experienced technologists also may be promoted to supervisor, chief radiologic technologist, and, ultimately, department administrator or director. Depending on the institution, courses or a master's degree in business or health administration may be necessary for the director's position.
Some technologists progress by specializing in the occupation to become instructors or directors in radiologic technology programs; others take jobs as sales representatives or instructors with equipment manufacturers.

What is the principle behind x-ray technique?
As with many of mankind's monumental discoveries, '''X-ray technology was invented completely by accident. In 1895, a German physicist named Wilhelm Roentgen made the discovery while experimenting with '''electron beams in a '''gas discharge tube. Roentgen noticed that a flouorescent screen in his lab started to glow when the electron beam was turned on. This response in itself wasn't so surprising -- fluorescent material normally glows in reaction to electromagnetic radiation -- but Roentgen's tube was surrounded by heavy black cardboard. Roentgen assumed this would have blocked most of the radiation.
Roentgen placed various objects between the tube and the screen, and the screen still glowed. Finally, he put his hand in front of the tube, and saw the silhouette of his bones projected onto the fluorescent screen. Immediately after discovering X-rays themselves, he had discovered their most beneficial application. '''''''''
Roentgen's remarkable discovery precipitated one of the most important medical advancements in human history. X-ray technology lets doctors see straight through human tissue to examine broken bones, cavities and swallowed objects with extraordinary ease. Modified X-ray procedures can be used to examine softer tissue such as the lungs, blood vessels or the intestines.
