anteroposterior position (AP)
the patient is placed with the anterior (front) part of the body facing the x-ray tube and the posterior (back) of the body facing the film; x-rays pass through the body from the front to the back in reaching the film
33
posteroanterior position (PA)
the patient is placed with the posterior (back) portion of the body facing the x-ray tube and the anterior (front) of the body facing the film; the x-rays pass through the body from the back to the front to reach the film
34
lateral position (lat)
the x-ray beam passes from one side of the patient's body to the opposite side to reach the film
35
supine position
the patient rests on the back, face upward, allowing the x-rays to pass through the body from the front to the back
36
prone position
the patient is placed lying face down with the head turned to one side; the x-rays pass from the back to the front side of the body
37
oblique position
the patient is placed so that the body or body part to be imaged is at an angle to the x-ray beam
38
diagnostic imaging
involves the use of x-rays, ultrasound, radiopharmaceuticals, radiopaque media, and computers to provide the radiologist images of internal body organs and processes
39
computed tomography (CT)
also known as a CAT scan (computerized axial tomography); it combines an advanced x-ray scanning system with a powerful minicomputer and has vastly improved imaging quality while making it possible to view parts of the body and abnormalities not previously open to radiography
40
gantry
the opening, donut-like hole of the CT scan machine
41
magnetic resonance imaging (MRI)
A noninvasive imaging technique; it's used to view organs, bone, and other internal body structures; the imaged body part is exposed to radio waves while in a magnetic field
42
cranial MRI
an MRI of the brain used to evaluate a person's tumor, seizure disorder, or headache symptoms
43
bore
horizontal tube running through the magnet from front to back
44
contrast agent
a special substance administered prior to or during the test; it is used to enhance internal structures and improve image quality, typically this material is injected into a vein in the arm
45
ultrasound
literally means beyond sound; it is sound whose frequency is beyond the range of human hearing; it is widely used in diagnostic imaging to evaluate a patient's internal organs
46
ultrasonography
the process of using ultrasound to produce a record of ultrasonic echoes as they strike tissues of different densities
47
sonogram or echogram
the record produced by ultrasonography
48
Doppler echocardiography
an adaptation of ultrasound technology; it is a noninvasive technique for determining the blood flow velocity in different locations in the heart
49
transducer
a handheld probe that is moved over an area of skin to examine the transmission of sound waves
50
thermography
detailed images of body parts are developed from data showing the degree of heat and cold present in areas being studied
51
scintigraphy
the production of two – dimensional images of tissue areas from the scintillations emitted by an internally administered radiopharmaceutical device that concentrates on a targeted site
52
angiocardiogram
x-ray record of the heart and great vessels made visible through the use of a radiopaque contrast medium
53
angiogram
x-ray record of the blood vessels made visible through the use of an injected radiopaque contrast medium
54
angiography
a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers
55

66
isotope
one of a series of nuclides that are chemically identical yet differ in atomic weight and electrical charge
67
lead (Pb)
metallic chemical element; soft, heavy, inelastic, malleable, ductile, bluish – gray metallic element used in its metallic form as a protective shielding against x-rays

70
oscilloscope
instrument used to record an electrical wave visually on a fluorescent screen of a cathode – ray tube
71

amount of radiation absorbed; the letters stand for (r)adiation (a)bsorbed (d)ose
72
radiation
process by which radiant energy is propagated through space or matter
73
radioactive
characterized by emitting radiant energy

77
radiography
process of making an x-ray record
78
radiologist
literally means one who specializes in radiology
79
radiology
scientific discipline of medical imaging using radionuclides, ionizing radiation, nuclear magnetic resonance, and ultrasound
80
radiolucent
pertaining to property of permitting the passage of radiant energy
