Neutron imaging has nothing to do with x-rays. Emergency rooms are not equipped with neutron imaging equipment, since neutron radiation can kill.

"Due to the high kinetic energy of neutrons, this radiation is considered the most severe and dangerous radiation to the whole body when it is exposed to external radiation sources."

—”since neutron radiation can kill.”
And so can most other energy across the spectrum, given the dose.

You might want to bone up on fast neutron therapy.

Not new and not in the emergency room, and most hospitals do not have an MRI in the ER.

Fast Neutron Therapy

Fast neutron therapy is a specialized and very powerful form of external beam radiation therapy. It is often used to treat certain tumors that are radioresistant, meaning they are very difficult to kill using conventional X-ray radiation therapy. It has proven to be very effective at treating salivary gland tumors and certain forms of cancer, such as adenoid cystic carcinoma...
