Artifacts: Digital – Computed Radiography (CR) / phosphor plates

Increased density E (increased exposure to x rays) E =↑ Exposure (x rays) This occurs when the phosphor plate is overexposed (i.e. using a molar setting for an anterior radiograph). Increased density due to incorrect time setting. Decreased density E (decreased exposure to x rays) E (increased exposure to visible […]

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 […]
