Computed Tomography01:10

Computed Tomography

7.5K
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...

Imaging Biological Samples with Optical Microscopy

8.0K
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...

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...

Summary
This summary is machine-generated.

Intraoperative optical coherence tomography (OCT) enhances ocular surgery by visualizing difficult structures, especially through cloudy corneas. This technology aids lamellar corneal procedures and other eye surgeries, though cost remains a barrier.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Surgical Technology

Background:

  • Coaxial microscopes struggle to visualize ocular structures, particularly through cloudy corneas.
  • Intraoperative optical coherence tomography (OCT) offers real-time visualization of ocular structures.
  • Surgeon-integrated OCT systems provide images directly in the oculars, minimizing the need to look away from the surgical field.

Purpose of the Study:

  • To highlight the revolutionary potential of intraoperative OCT in lamellar corneal surgery and other ocular procedures.
  • To discuss the specific applications and benefits of intraoperative OCT in various ophthalmic surgeries.
  • To identify the primary barriers to the widespread adoption of intraoperative OCT technology.

Main Methods:

  • Review of intraoperative OCT applications in lamellar corneal surgery.
  • Discussion of OCT's utility in visualizing structures through cloudy corneas.
  • Analysis of surgeon-integrated OCT systems versus monitor-based systems.

Main Results:

  • Intraoperative OCT facilitates graft assessment in Descemet stripping endothelial keratoplasty and graft orientation in Descemet membrane endothelial keratoplasty.
  • It improves intraoperative control and dissection plane assessment in deep anterior lamellar keratoplasty, especially when a "big bubble" technique is not feasible.
  • OCT aids in judging scar depth, evaluating intraocular lens positioning, and removing retained nuclear fragments in challenging surgical conditions.

Conclusions:

  • Intraoperative OCT significantly enhances visualization and control in various ocular surgeries, particularly lamellar corneal procedures.
  • Its ability to provide real-time imaging through cloudy media makes it invaluable for complex cases.
  • The primary obstacle to the widespread adoption of intraoperative OCT is its high cost.
