Challenges Associated With X-ray Imaging of Stretcher-Bound Patients
Radiologic Technology
|January 5, 2018
Summary
Imaging patients on stretchers presents unique challenges. This review covers technical difficulties like automatic exposure control unavailability and stretcher design variations for better stretcher-bound patient imaging.
Area of Science:
- Radiological imaging techniques
- Medical device engineering
Background:
- Patients frequently require imaging examinations while remaining on stretchers to prevent injury exacerbation.
- Imaging stretcher-bound patients introduces unique physical and technical considerations compared to standard tabletop imaging.
Purpose of the Study:
- To review the challenges and technical considerations specific to imaging patients who are bound to stretchers.
- To identify key variables affecting image quality and safety when imaging on stretchers.
Main Methods:
- Review of existing literature and technical guidelines for stretcher-based imaging.
- Analysis of factors including automatic exposure control (AEC) system functionality, grid usage, geometric considerations, and stretcher design.
Main Results:
- Automatic exposure control (AEC) systems are often unavailable or function differently on stretchers.
- Variability in stretcher design impacts patient positioning and image acquisition.
- Differences in grid types and geometric factors necessitate specific protocols for stretcher imaging.
Conclusions:
- Imaging stretcher-bound patients requires specialized approaches due to technical limitations and equipment variability.
- Understanding these challenges is crucial for optimizing image quality and patient safety in diagnostic imaging departments.

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...

The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

01:20Imaging Studies for Cardiovascular System III: X-Ray
500
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...

X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...
