Radiology as an Imaging Science Flashcards
Radiation is energy that is transmitted by what
waves through
space or through a medium (matter)
It is energy emitted and transferred to matter
and/or space in the form of waves and/or
particles.
Radiation
combination of electricity
and magnetism
Electromagnetic
It is an electrical machine that contains an
evacuated vacuum glass cylinder called an x-ray tube which produces a high speed of electrons to generate x-ray to provide images of internal structures
X-ray Machine
is produced with heat
Electrons
heart of the x-ray machine
X-RAY TUBE
manipulate technical factors
CONTROL (operating) CONSOLE
high voltage transformers that converts 220 V into 220,000 kVp
HIGH VOLTAGE SECTION
Two main parts of x-ray tube
Cathode and Anode
the negative side of the x-ray tube
Cathode
the positive side of the x-ray tube
Anode
It is the section where you manipulate the x-ray
machine to provide technical factors necessary in the production of an x-ray
Control Panel
made of lead that protects the
radiographer from x-ray
Glass
x-ray cannot penetrate
Lead
It is composed of a high voltage transformer that converts 220 volts to thousand volts and electrical circuitry
High Voltage Section
digital x-ray machine
High Frequency Generator
It is a special photographic film consisting of an
emulsion-gelatin containing radiation and light-sensitive silver halide crystals and a flexible
transparent blue-tinted base
X-ray Film
It is a flat, light-tight rectangle or square plastic or metallic container used to hold x-ray film and
intensifying screens and backed by lead to eliminate the effects of backscatter radiation
Film Cassette
It is part of the radiographic cassette made of
phosphor material which converts the energy of the x-ray beam into visible light
Intensifying Screen
made of GBX filter that emits red light in the darkroom to prevent x-ray beam from getting exposed to visible light
Safelight
pass film cassette without going out of the x-ray room and/or darkroom
Passbox
measure thickness of patient’s body
Caliper
It is a type of protective clothing that acts as a
radiation shield against secondary or scatter
radiation
Lead Rubber Apron
It is a protective shield placed outside of the body to cover the area of the gonads(testicles or ovaries) and other parts of the reproductive system of childbearing years or younger
Gonadal Shield
These are protective shielding accessories to shield your hands against radiation during x-ray
examination
Lead Gloves
It is a lead collar that wraps around the neck to block radiation during x-ray examination
Thyroid Shield
These are protective shielding accessories to shield your eyes against radiation (cataract) during x-ray examination
Lead Goggles
The process or technique of producing images on the film by means of x-ray or any other forms of radiation. The chemicals involved in manual, automatic, and daylight processors are basically the same
Film Processing
Enumerate the Four Film Processing
- Manual processing
- Automatic processing
- Printing(laser printing)
- Digital processing
X-rays are produced when high speed of electrons are suddenly stopped or decelerated. When this happens, 99% is converted to heat and only 1% of x-ray is produced
X-ray Production
With its beneficial diagnostic provision, harmful effects are the minimal drawback of these machines. Radiation health workers must always balance the benefits and the risks involved in every diagnostic procedure by practicing what?
