A method of standardizing the evaluation of a student radiologic technologist's performance in the clinical setting.
Clinical competancy evaluation
Refers to classroom lectures and demonstration of theories, as well as to facts an background info necessary to understand a specific body part.
Cognitive learning
Involves attitudes, values, and feelings.
Affective learning
The actual hands-on phase- the application of previously learned material.
Psychomotor learning
When the student is only observing.
Passive participation
When the student is performing few various tasks.
Direct supervision
The student will perform all aspects of the procedure with remote supervision of a RT.
Independant clinical performance. (indirect supervision)
Criteria for performance evaluation.
1)Physical facilities ready
2)Patient/Tech relationship
3)Positioning skills
4)Equipment Manipulation
5)Evidence of rad protection
6)Radiograph demonstration-Image Evaluation
7)Standard Rad Exposure- Image Evaluation
The ARRT passed a law to continue education. How?
Obtain 24 hr additional credit OR pass and exam in an additional discipline
The primary items needed for the production of x-rays.
1)a source of electrons
2)a means to accelerate the e
3)a way to bring the e to a sudden stop
An evacuated glass bulb with positive and negative electrodes.
x-ray tube
The electrode to which negatively charged e migrate.
A filament that gives off e when heated(the source of e)
The result of the sudden deceleration of the e at the anode.
energy conservation
Primary by-product of the energy conservation.
heat (>99%)
Secondary by-product of the energy conservation.
x-rays going in all directions (<1%)
The ability to post-process images in a variety of ways to provide multiple views of the anatomy.
digital imaging
What type of film allows you to change the imagein digital?
soft copy film
A sheet of plastic that is embedded with crystals called phosphors.
intensifying screen
What % of the image on the film is made by light from the intensifying screen?
A sheet of polyester plastic coated with a thin layer of gelatin and silver compounds.
x-ray film
Provides a live-action vew of the interior of the body.
Allows an image to be captured, saved in a computer, and post-processed.
Electronically improves and enhances the image and transmits it to the tv moniter.
image intensifier
Provides cross-sectional views of the body.
Computed Tomography
Allows cross-sectional views of the body to be made without the use of ionizing radiation.
The body part in ? is exposed to a magnetic field and radio wave transmission.
Magnetic Resonanse Imaging
What happens in MRI?
Tissues resonate giving up another radio wave captured by an antenna.
Uses a radiopharmaceutical infected into the circulatory system to image the area of interest.
Used to evaluate the physiology or function of an organ or system in the body.
Positron Emission Tomography
aka- coincidence imaging
Emission caused by body tissues.
511 kEv x-ray photons
The radioactive material concentrates in the area of interest and emits radiation; this radiation is then detected by a sensing device and is computed into an image.
Nuclear medicine
What kind of particles are NOT used in Nuc Med?
alpha particles
How can radioactive materials in nuc med be introduced to the body?
injected, swallowed, inhaled
Used in areas such as the OR, PAR, ICU, CCU, burn unit, orthopedic unit, and morgue.
portable radiography
Used primarily in the operating room, where the surgeon must see the images immediately.
portable fluoroscopy
(aka- C-arm)
A technique used to obtain radiographs of a section or slice of the body.
What is the current primary use of conventional tomography?
Intravenous urograms
Uses high-frequency sound waves, which is a form of non-ionizing radiation, to obtain sectional images of the body.
Used to evaluate moving organs.
Type of sonography used to evaluate blood flow through the arteries.
Doppler technique
Brings digital imaging together with hospital and radiology info systems; it allows for the total management of a patient's case.
Picture Archiving and Communication System
A standard protocol used for blending PACS and the various imaging modalities.
Digital Imaging and Communications in Medicine
Reomoving clothing and jewelry that may be covering the area of the body through which the x-rays must pass.
external preparation
Includes cleansing enemas.
so objects are not obscured by gas and fecal matter.
internal preparation
Solutions or gases introduced into the body to provide contrast on a radiograph between an organ and its surrounding tissue.
contrast media
Element with high atomic number.
X-rays do not readily pass through.
Solutions that contain this element are placed in organs and blood vessels to provide a contrast.
Cannot be absorbed by the body.
The medium of choice for gastrointestinal studies.
Radiographic studies of the urinary system.
excretory urogram
aka-intravenous urography/pyelograms
A study of the esophagus, requires the patient to swallow barium sulfate preparation.
Studies of the stomach performed with the use of barium sulfate.
upper gastrointestinal (GI) series
Radiographic exam of the colon that involves introducing a barium solution into the colon.
barium enema
What does a BE rule out or let you see?
A study of the urinary bladdr, involves filling the bladdr with a contrast agent.
The patient empties the bladder while under fluoroscopic observation.
voiding cystourethrogram

A radiographic study of the breast.
An exam of the subarachnoid space of the spinal cord.
A study of the salivary glands after they have been injected with a contrast agent.
