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
|
Cost
|
|
Imager 1
|
60 keV
|
250 mR
|
$20,000
|
|
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.
