Computed Tomography01:10

Computed Tomography

7.0K
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...

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...

Imaging Biological Samples with Optical Microscopy

7.7K
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

Area of Science:

  • Dermatology
  • Medical Imaging
  • Optical Coherence Tomography

Background:

  • Optical coherence tomography (OCT) is increasingly used in dermatology for quick, intuitive diagnosis of skin conditions.
  • Its primary applications include epithelial skin tumors like basal cell carcinomas and actinic keratoses.
  • OCT aids in monitoring treatment response and recurrence, potentially reducing the need for invasive biopsies.

Purpose of the Study:

  • To highlight the expanded applications of OCT and dynamic OCT (D-OCT) in dermatology.
  • To showcase the non-invasive assessment of both oncologic and non-oncologic skin diseases.
  • To emphasize the measurement of objective physiological skin parameters.

Main Methods:

  • Utilizing OCT and dynamic OCT (D-OCT) for in-vivo skin imaging.
  • Employing automated vascular imaging and objective parameter measurements.
  • Non-invasive analysis of skin structures and blood flow.

Main Results:

  • OCT enables rapid diagnosis and monitoring of skin tumors, including basal cell carcinomas and actinic keratoses.
  • Dynamic OCT expands applications to inflammatory dermatoses (e.g., eczema, psoriasis) and physiological parameters.
  • Objective measurements include epidermal thickness, blood flow, optical attenuation, and skin roughness.

Conclusions:

  • OCT and D-OCT offer valuable non-invasive tools for dermatological diagnosis and management.
  • These technologies facilitate objective, standardized assessment of diverse skin conditions.
  • Potential applications span from skin cancer detection to monitoring inflammatory diseases and wound healing.
