What is BS EN IEC 62985 - Size-specific dose estimates (SSDE) about?
BS EN IEC 62985 discusses computed tomography. BS EN IEC 62985 applies to CT scanners that can display and report CTDIVOL in accordance with IEC 60601-2-44, and radiation dose index monitoring software (RDIMS). And are for the purpose of calculating, displaying, and recording the size-specific dose estimate (SSDE) and its associated components.
BS EN IEC 62985 provides standardized methods and requirements for calculating, displaying, or recording SSDE, SSDE(z), water equivalent diameter (DW), and DW(z), where z represents a specific longitudinal position of the scanned object.
BS EN IEC 62985 provides a method of determining a reference water equivalent diameter, DW, REF(z), using CT scans of two cylindrical water phantoms and one or more anthropomorphic phantom(S), which conform to the specifications defined in BS EN IEC 62985. The method of calculating the water equivalent diameter that is implemented by the manufacturer, DW, IMP(z), is tested and validated against DW, REF(z) using the test objects and methods defined within BS EN IEC 62985.
BS EN IEC 62985 also describes the methods for calculating SSDE and DW, which represent the average values of SSDE(z) and DW(z) over the reconstruction length.
Note: This standardization is important to ensure that comparisons between reported SSDEs are valid.
Who is BS EN IEC 62985 - Size-specific dose estimates (SSDE) for?
BS EN IEC 62985 on calculating size-specific dose estimates (SSDE) on computed tomography is useful for:
- Computed tomography equipment manufacturers
- Medical laboratories and test centres for Computed tomography
- Regulatory authorities
Why should you use BS EN IEC 62985 - Size-specific dose estimates (SSDE) on?
The size-specific dose estimate (SSDE) is an estimate of the average absorbed dose to the scan volume that considers the attenuation of the anatomy being scanned (using the water equivalent diameter DW) and the radiation output of the CT scanner (using CTDIVOL).
BS EN IEC 62985 provides best practice guidelines on Characteristics, Generation, and verification of DW, REF(z), DW, IMP(z), and DW, IMP(z) for the water phantoms for calculating size-specific dose estimates (SSDE) on computed tomography. BS EN IEC 62985 also provides Requirements and limitations on Pre-scan display of SSDE, Post-scan updating of SSDE and DW, Pre-scan and post-scan display of SSDE and DW, Post-scan recording of SSDE, DW for CT scanners, and Limitations of calculation and display of SSDE and DW for calculating size-specific dose estimates (SSDE) on computed tomography.
The methods provided in BS EN IEC 62985 helps you conduct the proper assessment for calculating size-specific dose estimates (SSDE) on computed tomography and provide reliable results. In addition, minimizes hazards to patients as well as to operators.
