As the lead engineer for a development team, you have to make a decision on what components to use for a new x-ray imaging system, which is going to be sold to the military for field use. The system is to be transportable and will provide digital x-ray images of injured body parts. Your team has evaluated the following components, and they all fulfill the military ruggedness specifications:
Xray tube with generator
Voltage Range
Max. Anode Current
Cost
Model A
20-80 kVp
25 mA
$15,000
Model B
30-120 kVp
40 mA
$20,000
Digital Image Receptor
Peak Sensitivity
Required Exposure
Imager 1
60 keV
250 mR
Imager 2
80 keV
150 mR
$30,000
Imager 3
100 keV
70 mR
$40,000
Considering all you know about the energy dependence of x-ray attenuation, image contrast and image noise, and also considering the patient welfare and marketability of your final product, identify the x-ray-tube/generator and imager that will be part of the final system and justify your choice. Provide your answer in typed form, double spaced, 150-200 words.
