Computed Tomography01:10

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Area of Science:

  • Dermatology
  • Medical Imaging
  • Biophotonics

Background:

  • Optical coherence tomography (OCT) is a noninvasive diagnostic imaging modality.
  • It provides real-time, in vivo visualization of superficial skin layers.
  • OCT utilizes an infrared broadband light source for imaging.

Purpose of the Study:

  • To evaluate the utility of OCT in dermatology.
  • To assess OCT's capability in diagnosing various skin conditions.
  • To compare OCT with other noninvasive imaging techniques.

Main Methods:

  • OCT imaging of skin architecture and changes.
  • Investigation depth up to 1-2 mm.
  • Resolution between 3-15 μm depending on the system.

Main Results:

  • OCT enables evaluation of skin lesions, including nonmelanoma skin cancers and inflammatory diseases.
  • It allows for quantification of skin changes and visualization of parasitic infestations.
  • OCT is useful for examining indications such as nail conditions.

Conclusions:

  • OCT is a quick and valuable diagnostic imaging technique for numerous clinical questions.
  • It serves as an effective addition or complement to dermoscopy, ultrasound, and confocal microscopy.
  • OCT enhances noninvasive skin assessment and diagnosis.
