Question

CT scanners do not detect details smaller than about 0.5 mm. Is this limitation due to the wavelength of x rays? Explain.

Answer 1

X-rays has wavelength between 0.01 nm to 10 nm. This range is far less than 0.5 mm. Hence x-ray is capable to take picture of object smaller than 0.5 mm. Hence wavelength of x-ray is not responsible for CT scanners limit not to detect object smaller than 0.5 mm. Reason for this limitation is detector thickness. It is measure of how small we can reconstructed image. This thiskness is around 0.5 mm.

I will be glad to see your comment if you have any query and thumb up if you are satisfied. Thanks....
