X is for x ray: Inverse square law and PID/cone length

This is the last week of post topics from the review for the hygiene written boards.  Today is the inverse square law and how this applies to changing the PID/cone length and exposure settings for a comparable image density. Inverse square law The inverse square law applies to any source […]


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 […]
