X is for x ray: Image Density

Today is all about image density and how different settings on the x ray unit as well as the subject being imaged will effect this.  The four topics I will be covering are: milliampere (mA), kilovoltage peak (kVp), exposure time, and subject thickness.  I have covered some of these topics…

x ray unit settings: putting it all together

Now that we’ve gone over how changing the different settings affect your final image, we will go over how to adjust the settings and produce an image of similar density.  First we’ll discuss kilovoltage peak (kVp) and then onto milliampere (mA). Kilovoltage peak (kVp) A few weeks ago we went…

x ray unit settings: time

This last setting on the x ray unit is one that can be changed on all x rays units.  🙂  However, it is also one of the least changed settings I have come across in private offices. Newer x ray units typically have preset times for different areas of the…

x ray unit settings: milliampere (mA)

This week will be covering the milliampere or mA setting on an x ray unit.  Changing the mA affects the QUANTITY of x rays produced.  Some units have a fixed mA (typically in the range of 7 – 12) and some are changeable (from 5 – 15).  For those units…

x ray unit settings: kilovoltage peak (kVp)

This is the beginning of a 4 week series going over the settings on a x ray unit and how they affect image quality.  The first topic I am going to cover is kilovoltage peak or kVp.  Changing the kVp on a unit is directly associated with the overall contrast…
