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...

Positron Emission Tomography

6.5K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Area of Science:

  • Biomedical optics
  • Medical imaging
  • Photoacoustic tomography

Background:

  • Linear-array photoacoustic computed tomography (LA-PACT) offers flexibility for tissue imaging but suffers from limited angular coverage.
  • Limited view in LA-PACT hinders the acquisition of high-quality anatomical and functional tissue information.

Purpose of the Study:

  • To develop an advanced photoacoustic computed tomography (PACT) system using a hyperbolic-array transducer.
  • To enhance stereoscopic photoacoustic imaging (PAI) of the carotid artery and improve diagnostic capabilities for vascular diseases.

Main Methods:

  • Developed a novel photoacoustic tomographic system incorporating a hyperbolic-array transducer.
  • The hyperbolic transducer geometry was designed to match spherical waves, increasing PA signal detection sensitivity.
  • Evaluated the system using control phantom experiments and in vivo imaging of rat carotid arteries and human forearms.

Main Results:

  • The hyperbolic-array PACT system achieved approximately 1/3 greater angular coverage compared to traditional LA-PACT systems.
  • Volumetric PA images of rat carotid arteries demonstrated the system's efficacy for vascular imaging.
  • Successful volumetric imaging of human forearm vasculature confirmed the system's potential for clinical applications.

Conclusions:

  • The developed hyperbolic-array PACT system significantly expands angular coverage and improves PA signal detection sensitivity.
  • The system shows strong potential for enhanced carotid artery imaging and assisting in the diagnosis of vascular diseases.
  • This technology holds promise for improving diagnostic accuracy in clinical settings for vascular conditions.
