Dynamic Spatial Reconstructor constructs a moving, 3-D lifesize image of an internal organ
Ultrasound or Sonography a device emits a high-frequency sound (radar) and records the echo on a monitor
Scintigraphy (Nuclear Medicine) unstable radioisotopes are introduced into the body, different organs collect and concentrate them; a scintillation counter scans the body and produces and image
Positron Emission Tomography radioisotopes are mroe precisely localized with the aid of computer imaging techniques
Magnetic Resonance Imaging or Nuclear Magnetic Resonance determines if the nuclei of a single element behave normally in response to magnetism; Noninvasive and does not use radiation
