Another factor could be legal regulations. X - ray procedures are highly regulated to ensure safety and proper use. If the 'untold stories' do not fall within the legal scope of acceptable x - ray usage, such as performing x - rays without proper authorization or for illegal research, then it cannot be done.
Regarding ethical issues, we need to re - evaluate the nature of the 'untold stories'. If they can be reframed into a legitimate medical or scientific context with proper safeguards in place, then it might be possible to consider x - ray usage. For example, if it's about historical artifacts and we can ensure no damage and proper protection of the items.
