Terminology Flashcards
Anode
Positively charged target in X-ray tube
Cathode( filament end)
Negatively charged target of X-ray machine
Most versatile device for defining the size and shape of the radiography beam
Collimator
ALARA
As low as reasonably achievable
Divides the body lengthwise into right and left portions. Cut exactly down the midline of the body, the right and left halves of the body are equal
Sagital plane
Divides the body into anterior and posterior portion the frontal plane is called the coronal plane
Frontal plane
Divides the body horizontally creating an upper (superior) and lower (inferior) body
Transverse plane
The skeletal systems consist of
bones joints cartilage and the ligaments associated with the joints
How many bones in the human body
206
Long bones
Longer than they are wide they are found in arms and legs
Short bones
Shaped like cubes and are primarily found in wrist and ankles
Flat bone
Thin. Flat and curved they form the ribs breast bones and skull
Irregular bones
Differently shaped and are not classified as long short or flat includes the hip bones , vertebrae and various bones in the skull
Peak kilovoltage(kVP)
The highest energy level of photons in the X-ray beam controls the quality or penetrating power of the photons in the X-ray beam
Milliamperes-seconds(más)
Product of electrons tube current and the amount of time in second that the X-ray tube activated is the main determinant of how much radiation is directed towards a patient during exposure.
