Proton Beam Radiography in Tumor Detection

Monoenergetic protons an highly sensitive to density variations and are capable of giving radiographs of very high contrast. As an initial step in exploring their diagnostic potential, protons with energies of 160 million electron volts are used in "contact radiography" on tumor-bearing hu...

Description
Summary:Monoenergetic protons an highly sensitive to density variations and are capable of giving radiographs of very high contrast. As an initial step in exploring their diagnostic potential, protons with energies of 160 million electron volts are used in "contact radiography" on tumor-bearing human brain specimens. The proton radiographs are compared with x-radiographs taken under identical specimen conditions.
