Information About Radiology
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
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
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
