X-ray Imaging01:24

X-ray Imaging

11.0K
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...

Imaging Studies for Cardiovascular System III: X-Ray

633
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...

Imaging Studies III: Computed Tomography

653
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...

Ultrasonography

8.4K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Area of Science:

  • Radiological imaging
  • Medical physics
  • Diagnostic radiology

Background:

  • Computed radiography (CR) systems are widely used for diagnostic imaging.
  • Optimizing imaging parameters is crucial for balancing image quality and patient dose.
  • Standardized techniques for CR imaging of specific anatomical regions are essential.

Purpose of the Study:

  • To develop and validate a methodology for optimizing computed radiographic techniques.
  • To establish optimal exposure settings for skull, chest, and pelvis imaging in standard patients.
  • To reduce radiation dose while maintaining diagnostic image quality.

Main Methods:

  • Utilized an anthropomorphic phantom to simulate patient imaging.
  • Varied exposure levels (kVp and mAs) to generate images.
  • Evaluated image quality using visual grading analysis and objective parameters like effective detective quantum efficiency (eDQE) and contrast-to-noise ratio (CNR).

Main Results:

  • Established gold standard techniques: 102 kVp/1.6 mAs (skull), 81 kVp/4.5 mAs (pelvis), and 90 kVp/3.2 mAs (chest).
  • Achieved significant X-ray dose reduction compared to existing service techniques.
  • Demonstrated that optimized techniques maintained diagnostic accuracy.

Conclusions:

  • A range of acceptable CR techniques exists, allowing dose optimization without compromising diagnostic capabilities.
  • Optimization should integrate quantitative (eDQE, CNR) and qualitative (visual grading) parameters.
  • The developed methodology provides a framework for optimizing CR protocols for various anatomical regions.
