Optical coherence tomography - Wikipedia, the free encyclopedia (2168 words) |
 | The axial and lateral resolutions of OCT are decoupled from one another; the former being an equivalent to the coherence length of the light source and the latter being a function of the optics. |
| In frequency domain OCT the broadband intereference is acquired with spectrally separated detectors (either by encoding the optical frequency in time with a spectrally scanning source or with a dispersive detector, like a grating and a linear detector array). |
| Parallel OCT using a charge-coupled device (CCD) camera has been used in which the sample is full-field illuminated and en face imaged with the CCD, hence eliminating the electromechanical lateral scan. |
| LightLab Imaging Technology (306 words) |
| Optical Coherence Tomography (OCT) is a promising new class of diagnostic medical imaging technology that utilizes advanced photonics and fiber optics to obtain images and tissue characterization on a scale never before possible within the human body. |
| Simply put, OCT combines the principles of ultrasound with the imaging performance of a microscope and a form factor that is familiar to clinicians. |
| OCT imaging can be performed over approximately the same distance of a biopsy at high resolution and in real time making the most attractive applications for OCT those where conventional biopsies cannot be performed or are ineffective. |
