COMP Imaging Lecture Series - Lecture 2: Multi-institution Consensus for Portable Chest Radiographs Through Glass Barriers
A method of acquiring portable chest radiographs (CXR's) through glass barriers, originally developed by the University of Washington, was implemented independently in several Californian facilities during the onset of the COVID19 pandemic in the spring of 2020.
To ensure the diagnostic image quality and radiation safely for patients and hospital staff in these condition, we performed a quantitative evaluation of image quality and exposure using six radiographic systems at five facilities. Specifically, we examined:
- Beam transmission
- Beam hardening
- Contrast-to-noise ratio
- Patient entrance air kerma (EAK)
- Patient effective dose
- Scatter surveys
With over a year of experience with this method, an assessment of clinical image quality and work flow will also be discussed.
The glass barriers attenuated a mean of 61% of the normal X-ray beams and require an approximate 2.5 times increase in bean intensity. This does not result in a significant increase in the radiation dose delivered to the patient or staff.
