WebBasic Principles. Optical coherence tomography (OCT) (Stratus OCT, Carl Zeiss Meditec, Inc., Dublin, CA) (Fig. 10.1) is a commercially available computer-assisted precision optical instrument that generates cross-sectional images (tomograms) of ocular structures with close to 10-μm axial resolution. 1 This technology is evolving, and its axial ... WebPositron emission tomography (PET) uses small amounts of radioactive materials called radiotracers or radiopharmaceuticals, a special camera and a computer to evaluate organ and tissue functions. By identifying changes at the cellular level, PET may detect the early onset of disease before other imaging tests can.

WebIf you would like to see how Micro-CT can support your research, we invite you to submit a sample to our lab for a FREE first scan. If we look at the Micro-CT process in more depth and examine some of the physical aspects, the process can be expanded to four steps: 1) Generate X-rays. 2) Transmit X-rays Through the Sample. WebIn computed tomography (CT), an x-ray tube moves around the body and continuously projects a thin fan of x-rays through the body. Electronic detectors opposite the tube continuously monitor the number of x-rays passing through the body and the angle at which the beam is being projected. The number of x-rays reaching the detector changes as the ...
