X-ray Imaging01:24

X-ray Imaging

7.7K
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

716
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...

Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

683
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 Imaging Physics
    • Radiological Technology
    • Patient Safety

    Background:

    • Public and media attention on radiation dose necessitates improved practices in medical imaging.
    • Ionizing radiation accidents have led to legislative changes and safety alerts, highlighting the need for enhanced professional awareness.
    • The Joint Commission's Sentinel Event Alert, issue 47, underscores critical issues in radiation safety.

    Purpose of the Study:

    • To inform radiology professionals about optimizing digital equipment for superior image quality and reduced patient radiation dose.
    • To explore the relationship between exposure parameters (kVp, mAs), exposure index, and digital image processing.
    • To establish a foundation for universal digital technique charts based on empirical testing.

    Main Methods:

    • Evaluation of optimal kilovoltage peak (kVp) and milliampere-second (mAs) settings for digital radiography.
    • Analysis of exposure index numbers to ensure accurate dose monitoring.
    • Testing of exposure techniques on anatomical phantoms to assess image quality and patient dose.

    Main Results:

    • Digital radiography allows for diagnostic image quality even with potential patient overexposure, lacking immediate warning signs.
    • Optimized exposure techniques, including appropriate kVp and mAs, are essential for dose reduction.
    • Exposure index serves as a critical tool for managing radiation dose in digital imaging.

    Conclusions:

    • Radiology professionals must be well-informed about digital equipment to balance image quality and patient safety.
    • Understanding digital processing risks, such as post-image manipulation, is vital to prevent unintended overexposure.
    • The development of universal digital technique charts is supported by phantom-based exposure technique testing.
