Single Photon Emission Computer Tomography (SPECT), is a computer system that uses radioactive gas to detect body particles that are displayed in the form of images. Another form is Position Emission Tomography (PET) is also a computer system that can display images using radioactive isotopes. Besides Nuclear Magnetic Resonance is a diagnostic technique by magnetizing the nucleus (atomic center) of a hydrogen atom. DNA computer, which is able to diagnose disease while giving medicine.
