Patient dose management in digital radiography.

Area of Science:

• Medical Imaging
• Radiology
• Health Informatics

Background:

• Digital radiography offers significant advantages for medical imaging.
• Effective patient dose management is crucial in modern radiology.
• Existing methods for auditing radiographic parameters can be improved.

Purpose of the Study:

• To describe the experience with patient dose management in digital radiography.
• To introduce an online audit tool developed for digital radiography.
• To demonstrate the application of the tool in various radiological procedures.

Main Methods:

• Development of tools to extract data from DICOM headers of digital images.
• Collection of radiographic parameters and calculation of patient entrance doses.
• Auditing of image quality and dosimetric parameters using collected data.

Main Results:

• The audit tool has been applied to mammography, chest imaging, computed radiography, and interventional radiology procedures.
• Data from over 25,000 mammography patients and 75,000 chest images were analyzed.
• Examples include skin dose distribution calculations in interventional cardiology and dosimetric parameters for 2006 cardiology procedures.

Conclusions:

• Digital radiology facilitates advanced imaging and patient dose management.
• Dose reports, QCONLINE systems, and MPPS DICOM service are valuable for procedure optimization and dosimetry data management.
• Implementing the IEC-DICOM standard for patient dose structured reports will further enhance dose management in digital radiology.
