35 Questions
What determines the maximum X-ray energy produced in an X-ray tube?
Voltage
How does the rate of X-ray production vary with the X-ray tube current?
It is directly proportional
In an X-ray tube, what happens when high energy electrons collide with the anode?
They interact with the anode material, creating typical radiation of the anode element
How does the energy of gamma rays typically compare to that of X-rays?
Gamma rays have higher energy (Mev's) than X-rays (KeV's)
Which type of radiation is typically shorter in wavelength than UV rays and longer in wavelength than gamma rays?
X-rays
What is the wavelength range of X-rays?
0.01 to 10 nanometers
Which part of the X-ray tube becomes strongly positive during the production of X-rays?
Anode
What happens when rapidly moving electrons strike a metal target in an evacuated glass tube?
X-rays are produced
Which type of radiation occurs when an inner shell orbital electron is removed and rearrangement of the atomic electrons results in the release of characteristic X-Ray energy?
Gamma rays
What is the energy conversion ratio of kinetic energy of the electrons into electromagnetic energy (x-ray) and heat?
1:99
What is the primary hazard associated with alpha particles?
They travel short distances and have large mass
What is the purpose of the focusing cup in the X-ray tube?
To force electrons to form a narrowing beam towards the target
When do gamma rays occur?
When the nucleus releases energy, usually after an alpha, beta, or positron transition
What is the main characteristic of beta particles?
They are emitted from electron orbits
Which type of radiation involves 2 neutrons and 2 protons and travels short distances with large mass?
Alpha particles

Which directional term refers to a movement towards the midline of the body?
Medial
Which of the following refers to the plane that divides the body into left and right halves?
MSP
What does the abbreviation 'ASIS' stand for in the context of radiography and medical imaging?
Anterior Superior Iliac Spine
What is the main purpose of a focusing cup in an X-ray tube?
To focus the electrons onto the anode target
What position is the body in when it is described as 'erect, face forward, feet together, arms at sides with palms forward'?
Anatomic position
Which body position term describes a patient lying face down?
Prone
In the left lateral decubitus position, which way is the patient lying?
On the left lateral side
What does the term 'posteroanterior projection' refer to?
When the beam enters the back and exits the front of the part
In radiography, what is the body position term for a patient lying down on the back?
Supine
Which body position term describes a patient standing with the left side of the body next to the cassette?
Left lateral erect
What does the term 'Decubitus Positions' refer to in radiography?
Supine & a horizontal beam is used
Which plane divides the body into anterior and posterior portions?
Coronal plane
In which joint movement does the angle of the joint decrease?
Extension
What directional term refers to a movement away from the midline of the body?
Lateral
Which term refers to a movement of the hand and forearm in which the palm is moved from facing anteriorly to posteriorly?
