Computed Tomography01:10

Computed Tomography

6.0K
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

161
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Area of Science:

  • Ophthalmology
  • Biomedical Engineering
  • Medical Imaging

Background:

  • Dynamic optical coherence tomography angiography (OCTA) is crucial for monitoring stimulus-evoked hemodynamics.
  • Challenges in dynamic OCTA include long acquisition times and large datasets, hindering real-time processing.
  • Existing methods struggle with efficient processing of 4D (3D space and time) datasets.

Purpose of the Study:

  • To develop a GPU-based real-time data processing pipeline for dynamic inverse SNR-decorrelation OCTA (ID-OCTA).
  • To overcome the limitations of long acquisition times and large data sizes in dynamic OCTA.
  • To enable high-quality, real-time angiographic imaging for hemodynamic studies.

Main Methods:

  • Implementation of a GPU-based real-time data processing pipeline for ID-OCTA.
  • Achieved a measured line-process rate of 133 kHz for real-time display of OCT and OCTA cross-sections.
  • Utilized automatic optimization of angiogram quality through real-time processing.

Main Results:

  • Real-time processing significantly improved vessel signal-to-noise ratio (SNR), contrast-to-noise ratio, and connectivity by 14.37%, 14.08%, and 9.76%, respectively.
  • Enabled motion-contrast 4D angiographic imaging of stimulus-evoked hemodynamics within a single trial in mouse retina.
  • Observed apparent dilation of retinal arterioles and venules and elevated decorrelation values in retinal plexuses following flicker light stimulation.

Conclusions:

  • GPU ID-OCTA provides a solution for real-time, high-quality angiographic imaging.
  • The developed pipeline is particularly suitable for dynamic hemodynamic studies.
  • This technology facilitates efficient monitoring of physiological responses in the retina.
