Question
Answer
show American Registry of Radiologic Technologists  
🗑
ASRT   show
🗑
JRCERT   show
🗑
LMXO   show
🗑
show Absorbtion of X-Rays  
🗑
show Device that contains a Moving grid  
🗑
Cassette   show
🗑
Central Ray   show
🗑
show A Box-Like device attached under the tube housing, allows you to vary the size of the Radiation field  
🗑
Computed Radiography(CR)   show
🗑
Control Booth   show
🗑
Control Console   show
🗑
Detent   show
🗑
show A system that contains X-Ray film and the film holder(cassette)  
🗑
show The "unseen" image, the image before it is processed to a "visable" one  
🗑
Radiation Field   show
🗑
show Remains of the primary beam after it has been attenuated by matter, "Exit Radiation", the pattern of the remnant radiation creates the image.  
🗑
Scatter Radiation   show
🗑
show The unwanted image exposure caused by the scatter radiation.  
🗑
show Or mass, Bone has greater mass, therefore will absorb more radiation than less dense tissue such as fat, this varies the intensity of the X-Ray beam  
🗑
show The head is 15 degrees lower than the feet  
🗑
Tube Housing   show
🗑
Tube Port   show
🗑
Upright Cassette Holder   show
🗑
show Cone shaped beam comming down from the tube port and housing, contains the central ray  
🗑
show The Source of X-Rays.  
🗑
Ampere(A)   show
🗑
Atom   show
🗑
show Energy that binds electrons to their own shell, electrons near the nucleus have more binding energy than those in outer shells  
🗑
show A substance that consist of only one type of molecule, Ex: Water(H2O)  
🗑
Circut   show
🗑
show Electric charges that drift or flow in a vacuum, in certain gases, liquids, and metals, connected to make a circut  
🗑
Current   show
🗑
show Consists of light, X-Rays, Radiowaves, microwaves, and other forms of energy. All have both electric and magnetic properties.  
🗑
Electron   show
🗑
Element   show
🗑
Frequency   show
🗑
show Used to expose radiographs, Greatly reduce the quanity of radiation necessary to produce an image. Are plates coated with fluorescent crystals.  
🗑
Ionization   show
🗑
KiloVolts Peak(kVp)   show
🗑
Mass   show
🗑
show dfdfg  
🗑
MilliApere(mA)   show
🗑
show fgsfg  
🗑
show Inside the nucleus, Mass number: 1, Charge: 0,neither attracts or repels one another  
🗑
show Neutrons and protons together form the nucleus of an atom and form the center, Electrons circle the nucleus in orbits called shells.  
🗑
Photon   show
🗑
show Is the Force or strength of the electron flow in the current. Measured in Volts(V), or kVp(kiloVolts peak)  
🗑
Proton   show
🗑
show fgsfg  
🗑
show Is any propetry of the circut that hinders the flow of current. Measured in Ohms. Depends on 4 factors: Material, length, diameter and temperature.  
🗑
Sine Wave   show
🗑
Transformer   show
🗑
show Unit to measure Potential difference,  
🗑
Wavelength   show
🗑
