How do different settings (kVp, mA, and C-arm distance) affect fluoroscope image quality? Does the resolution change, and if so, why? (Hint: Think of this in terms of photon interactions.)

Expert Solution

Fluoroscopy is an important diagnostic and interventional imaging tool which helps medical professionals to view real-time images of anatomy and function of all long bones with good imaging quality. There are many factors that affect the amount of radiation delivered, particularly during the course of long interventional procedure.

Normally, fluoroscopy consume less kVp (kilo-voltage peak) and mA (milli-ampere) but still still produce good image quality of all long bones.

The kvp range is between 45 to 55.

The mA range is between 1.2 to 1.7.

C-arm is a mobile unit of imaging used in fluoroscopy. It also consists of a settings where we can view, manipulate and transfer data. The quality of image may vary depending on the operator’s knowledge.

The fluoroscopy exposure rate for adult is around 30 mGy/min, where 10mGy/min is equal to 1 rad.

Explain the concepts of “luminosity distance” and “proper distance”, and how they are different. How does the observed bolometric flux, f, from a distant source with luminosity, L, depend on redshift, z? What factor(s) cause(s) this redshift dependence? Describe the properties of a universe where the luminosity distance would be identical to the proper distance.
