Tube Current (mA)
Category Exposure Parameter Term Tube Current (mA) Definition of Tube Current (mA) Electron Current In X Ray Tube Controlling Photon Flux And Image Noise Notes About Tube Current (mA) Often Modulated For Dose Optimization
Exposure Parameter
Kilovoltage Peak (kVp)
Category Exposure Parameter Term Kilovoltage Peak (kVp) Definition of Kilovoltage Peak (kVp) Peak Voltage Applied Across X Ray Tube Determining Beam Quality And Penetration Notes About Kilovoltage Peak (kVp) Higher kVp Increases Penetration And Reduces Subject Contrast
Milliampere Seconds (mAs)
Category Exposure Parameter Term Milliampere Seconds (mAs) Definition of Milliampere Seconds (mAs) Product Of Tube Current And Exposure Time Determining Total X Ray Quantity Notes About Milliampere Seconds (mAs) Directly Proportional To Receptor Exposure And Patient Dose
Tube Voltage (kVp)
Category Exposure Parameter Term Tube Voltage (kVp) Definition of Tube Voltage (kVp) Peak Kilovoltage Across Tube Determining Photon Energy Spectrum And Contrast Notes About Tube Voltage (kVp) Lower kVp Increases Contrast For Iodine But Raises Noise
