Question 2 of 21
In what year was X-ray technology developed?
... X-rays, which use electromagnetic radiation to create images of tissue, was by developed by German physicist Wilhelm Rontgen in 1895.
Question 3 of 21
Which of the following is Positron Emission Tomography (PET) primarily used for today?
... Although PET was originally used primarily to monitor brain sections as they engaged for specific tasks, it is now overwhelmingly used to study brain functions related to neurotransmitters, which are brain chemicals that relay signals between nerve cells.
Question 4 of 21
During pregnancy, transvaginal ultrasound imaging is NOT normally used for which of the following reasons?
... Transvaginal ultrasound technology is normally used only during the first and second trimester. It can provide clearer images of very early pregnancies and pregnancies of overweight mothers. It can identify problems such as ectopic pregnancies and fetal abnormalities.
Question 5 of 21
An EEG (electroencephalogram) measures electrical activity in the brain. It can NOT be used to _________.
... Although it has numerous brain-related functions, an EEG cannot be used to detect the presence of mental illness.
Question 6 of 21
Repetitive Transcranial Magnetic Stimulation (rTMS) is used as a non-invasive therapy for ________.
... rTMS is used clinically to improve motor coordination that has been lost due to imbalances between the brain hemispheres. In addition, it is used experimentally in patients with Parkinson's, dystonia and schizophrenia
Question 7 of 21
What was the first medical use of X-ray technology?
... In 1896, an X-ray was used in Canada to locate a bullet lodged in a patient's leg.
Question 8 of 21
Ultrasound technology was often used in neurology until the 1960s, when it dropped out of favor because ________.
... Ultrasound works by measuring the elapsed time between an ultrasonic pulse and its echo within the body. For neurological uses, the skull was found to interfere with the sound waves, making results inaccurate. Ultrasound instead became very valuable in obstetrics and gynecology.
Question 9 of 21
The first attempt at using magnetic resonance imaging (MRI) was unsuccessful because _______.
... Dr. Raymond Damadian, developer of the MRI, was the first test subject. He proved to be too large to be imaged in the machine. A much smaller graduate student was the first successful MRI subject in 1977.
Question 10 of 21
Computer Assisted Tomography (CT), developed in the 1970s, is an upgrade over earlier X-ray technology because __________.
... A CT scan produces three-dimensional images of bone, soft tissue and air in the body. It was such an advance that its developers won the 1979 Nobel Prize for Medicine or Physiology.
Question 11 of 21
The Department of Homeland Security is funding a private corporation to develop X-ray imaging based on the vision of the ________.
... The Lobster Eye X-ray Imaging Device (LEXID) is modeled after the eye of the lobster, which works through reflection, not refraction. It is much more efficient than traditional X-rays and can even perform imaging through concrete, wood and steel.
Question 12 of 21
Open MRI technology was developed to help patients who are oversized or _________.
... An open MRI allows more space around the patient. It is far less restrictive and much more comfortable, especially for patients who are large or claustrophobic.
Question 13 of 21
Law enforcement personnel can use thermal imaging when investigating automobile accidents to _______.
... Many modern cars having anti-lock brakes, so skid marks are not left at accident scenes. But the friction between tires and road due to braking can be thermally imaged for about 30 minutes after an accident.
Question 14 of 21
Angiography is used in conjunction with which imaging technology?
... During an angiography, dye is injected into a blood vessel to help X-rays uncover a blockage or narrowing of arteries.
Question 15 of 21
What is the storage policy for a passenger's image that has raised suspicions after being created by the Transportation Security Administration's (TSA) Backscatter unit?
... Backscatter technology allows a TSA screener to view a chalk-like image of each person. If anything incongruous appears, that passenger receives further review. The image is then erased.
Question 16 of 21
The ballistic imaging technology used by law enforcement personnel is ______ DNA technology.
... Ballistic imaging technology is less accurate than both DNA and fingerprint-matching technologies.
Question 17 of 21
When looking for a missing person in an open area, thermal imaging can help police search about _______ feet/kilometers in any direction.
... Police often use thermal imaging to search for children or seniors who have wandered away from their homes. Images can be detected up to 1,500 feet (2,414 kilometers) away.
Question 18 of 21
Laser Doppler Ultrasound is used to measure _________.
... Laser Doppler Ultrasound measures changes to blood flow in the arteries, which helps doctors who are treating patients with head traumas, in comas and in intensive care.
Question 19 of 21
Deep brain stimulation (DBS) electrical imaging is being used experimentally for patients with epilepsy to _________.
... Researchers use DBS on patients with epilepsy who will be undergoing surgery to control seizures. The imaging is used to identify the parts of the brain involved in the seizures so uninvolved areas are not affected by the surgery.
Question 20 of 21
In 2010, at the University of Virginia Medical Center, radiation therapy was used in conjunction with MRI to attack a tumor causing _______.
... The tallest man in the world (according to the Guinness Book of World Records) underwent radiation therapy that stopped his growth at 8 feet, 3 inches (2.51 meters).
Question 21 of 21
One type of imaging technology used by the TSA is the millimeter wave unit, which uses ________.
... The millimeter wave unit bounces electromagnetic waves off a passenger within an imaging portal, and a generic figure appears to the TSA official.
