Chapter 1 Introduction to Imaging and Radiologic Sciences

The measurement of bone density using dual energy x-ray absorptiometry (DEXA or DXA) to detect osteoporosis

Radiologic procedures for the diagnosis and treatment of diseases of the cardiovascular system

Recording of a predetermined plane in the body using an x-ray beam that is measured, recorded, and then processed by a computer for display on a monitor

Visualization of deep structures of the body by recording the reflections of pulses of ultrasonic waves directed into the tissue

Capacity to operate or work

Any process by which a neutral atom gains or loses an electron, thus acquiring a net charge

Process of using a magnetic field and radiofrequencies to create sectional images of the body

Radiography of the breast

Branch of radiology that involves the introduction of radioactive substances into the body for both diagnostic and therapeutic purposes

Energy transmitted by waves through space or through a medium

Branch of radiology involved in the treatment of disease by means of x-rays or radioactive substances

Making of records (radiographs) of internal structures of the body by passing x-rays or gamma rays through the body to act on specially sensitized film or an imaging plate or system

General term applied to an individual who performs radiography, radiation therapy, or nuclear medicine technology

Physician who specializes in the use of roentgen rays and other forms of radiation in the diagnosis and treatment of disease

An advanced level radiographer who extends the capacity of the radiologist in the diagnostic imaging environment, thereby enhancing patient care

Branch of health sciences dealing with radioactive substances and radiant energy and with the diagnosis and treatment of disease by means of both ionizing (roentgen rays) and nonionizing (ultrasounds) radiation

Also known as X-Ray; Electromagnetic radiation of short wavelength that is produced when electrons moving at a high velocity are suddenly stopped

_____Is a form of mechanical energy.

is a method of imaging the electrical activity of the head

is a method of imaging the electrical activity of the heart

The body's naturally emitted heat energy can produce images for diagnostic purposes as well. These images are called

Is emitted by nucleous of an atom.

Nuclear medicine technology uses Nuclear energy to create images of both:

is a form of electromagnetic energy that has the ability to ionize atoms

The field of radiologic technology began on ___________________________

In 1895 he discovered x-rays

Rontgen termed these invisible rays "x-rays" because X is the symbol for an _______ variable

A Radiographer uses ____________ to permit visualization of the gastrointestinal (GI) tract and genitourinary system

Is the term for radiologic examination of the blood vessels after injection of contrast media.

Placing a catheter into one of the chambers of heart is termed

tratment of a blocked blood vessel is termed

Nuclear medicine procedures usually involve the imaging of a patient's organs -such as the liver, heart, or brain- after the introduction of a radioactive material known as a:

Involves the use of high-energy ionizing radiationto treat malignant tumors (cancer)

Are involved in treatment planning and dose calculations.
