BS EN IEC 61223-3-5:2019

What is BS EN IEC 61223‑3‑5-Imaging performance of computed tomography X-ray equipment about?  

BS EN IEC 61223‑3‑5 is the third part of the multi-series standard that discusses the evaluation and routine testing in medical imaging departments. BS EN IEC 61223‑3‑5 applies to CT scanners that conform to IEC 60601-2-44:2009, IEC 60601-2-44:2009/amd1:2012 and IEC 60601-2-44:2009/and 2:2016. 

BS EN IEC 61223‑3‑5 defines the essential parameters which describe the performance of CT scanners about image quality, radiation output, and patient positioning; the list of parameters to be tested can be found in 4.3, defines the methods of testing the essential parameters, and evaluates compliance with the tolerances of the parameters specified by the accompanying documents. 

The methods defined in IEC 60601-2-44 and BS EN IEC 61223‑3‑5 rely on non-invasive measurements, using appropriate test equipment, performed during or after installation. signed statements covering steps in the installation procedure can be used as part of the acceptance test report. 

Who is BS EN IEC 61223‑3‑5-Imaging performance of computed tomography X-ray equipment for? 

BS EN IEC 61223‑3‑5 on the Imaging performance of computed tomography X-ray equipment is useful for: 

• Manufacturers of computed tomography X-ray equipment 
• Test centres for computed tomography X-ray 
• Hospitals 
• Medical laboratories 
• Regulatory authorities 

Why should you use BS EN IEC 61223‑3‑5-Imaging performance of computed tomography X-ray equipment? 

X-ray computed tomography (CT) is a non-destructive technique for visualizing interior features with solid objects, and for obtaining digital information on their 3D geometries and properties. X-ray attention is primarily a function of X- rays energy and the density and composition of the materials being imaged. 

BS EN IEC 61223‑3‑5 guideline helps you with General aspects of acceptance tests, constancy tests, test methods for CT scanners on the positioning of the patient support, patient positioning accuracy, reconstructed section thickness, mean CT number, the magnitude of noise, and uniformity, spatial resolution (high contrast), automatic exposure control (AEC), and low contrast resolution and low contrast detectability for imaging performance of computed tomography X-ray equipment. 

BS EN IEC 61223‑3‑5 improves the safety and imaging performance of computed tomography X-ray equipment. In addition, minimizes hazards to the patient and operator. 

What’s changed since the last update? 

BS EN IEC 61223‑3‑5:2019 supersedes IEC 61223‑3‑5:2019, which has been withdrawn. BS EN IEC 61223‑3‑5:2019 has some technical changes with respect to IEC 61223‑3‑5:2019. These includes: 

• Modification of the RADIATION protection and control 
• Modification of the acceptance testing 
• Introduction of constancy testing
