X-ray Imaging01:24

X-ray Imaging

11.1K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Positron Emission Tomography

8.1K
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...

Imaging Studies for Cardiovascular System III: X-Ray

682
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Area of Science:

  • Medical Physics
  • Computer Science
  • Radiotherapy

Background:

  • External beam X-ray therapy (XRT) and proton therapy (PT) are established cancer treatments requiring complex computerized planning.
  • Current planning systems lack adequate visual tools to integrate patient data with treatment device geometry, risking collisions.

Purpose of the Study:

  • To develop a cost-effective method for real-time extraction of patient-specific 3D surface representations (S-reps).
  • To create a comprehensive simulation of XRT/PT treatment rooms by combining S-reps with treatment system geometry.
  • To improve visual aid in radiation therapy planning to prevent unforeseen collisions.

Main Methods:

  • Utilizing 3D surface representation (S-rep) technology, adapted from CAD/CAM and gaming.
  • Developing a real-time extraction process for patient-specific S-reps.
  • Integrating extracted S-reps with treatment system geometry for a complete simulation environment.

Main Results:

  • A web-deployable simulator was implemented using the X3D standard.
  • The simulator facilitates remote collaboration, simulation, and training for specialists.
  • It also serves as an educational tool for patients.

Conclusions:

  • Objective assessments confirm the accuracy of the generated S-reps.
  • The developed simulator shows significant potential for clinical application in radiation therapy.
