The dramatic change from empirical to scientific technology in medicine: computerized imaging, communications and holography.

Perhaps the single most important element in the rapid development of contemporary diagnostic imaging is simply its feasibility that results from the deliberate use of complicated, but powerful, mathematical formulation. Implemented with various types of computers, today mostly digital, in such applications at CT (computerized tomography), MRI (magnetic resonance imaging) and others, the underlying principles of the 3-D (three-dimensional) image recording and reconstruction can all be traced back to the principles of "holography". Further improvements in image communications and processing, for example in view of robotized "Imaging-guided Stereotactic Diagnosis and Treatment" in high-field MRI is likely to result from suitable use of "Fuzzy Logic".

Diagnostic Imaging

Optical holographic three-dimensional ultrasonography.

Three-dimensional ultrasonograms prepared by superposition optical holography improves anatomical orientation and reduces the volume of data needed to study parenchymal organs such as breast, liver, kidney, spleen, and others. An optical hologram makes it possible to simultaneously view multiple planes of observations and see through and around structures without the superimposition of overlying structures. The use of pulse echo ultrasonograms results in better resolution and gray scale and permits multiplane viewing eliminates the geometric distortions present in acoustical holography.
