Question | Answer |
---|---|
what is an x-ray | a form of electromagnetic radiation that travels in in waves |
what is an anode | the side of the x-ray tube with the positive charge |
what is the cathode | the side of the x-ray tube with the negative charge |
how are negatively charged electrons produced | by the tungsten filament |
name five parts of the x-ray machine | control panel, x-ray tube, collimator, moveable table, bucky tray |
what are the components involved in creating x-rays | milliamperage (mA), kilovoltage (kvp), time (sec) |
what is milliamperage (mA) | the amount of energy in the circuit, number of electrons produced |
what is kilovoltage peak (kvp) | acceleration of electrons between anode and cathode , how fast / intensity |
what is the time component | the period which the x-rays are permitted to leave the xray tube measured in fractions of seconds |
how do we measure the object being radiographed | in cm |
what is the difference between the x-ray vs radiograph | xray is the energy that is used in the beam that passes through an object to produce an image. |
