Thermal imaging is not comparable to a x-ray. However thermal imaging has been compared to x-ray vision. Nevertheless, both x-rays and thermal imaging are both important. They both have different uses.
The practical answer for medical imaging is, no. The presence of aluminum foil would fully block a standard X-ray beam and make it impossible to assess underlying structures.
A lung cancer can be detected by X-ray imaging.
If you mean, will x-ray imaging be replaced by other medical diagnostic techniques, the answer is certainly yes. At this time, magnetic resonance imaging can give much greater detail and can be used for a variety of tissues in the body, other than hard tissues only like x-ray imaging. X-ray imaging is still used predominantly for simple diagnoses like bone fractures because it is cheap, simple, and fast. The technology for x-ray imaging has reduced the risks from x-ray exposure, so as long as it is the cheapest and easiest method for certain diagnoses, x-ray imaging will be common.
A radiology technician typically works in a X-ray or imaging laboratory. He or she performs diagnostic imaging procedures in nuclear medicine such as X-ray, computed tomography (CT), magnetic resonance imaging (MRI), fluoroscopy and mammography.
