Abstract:
In this paper, we evaluated the implementation of a digital signature for medical imaging quality assurance and control (QA/C) by a technician in accordance with the Digital Image and Communication in Medicine (DICOM). After QA/C, a set of DICOM images were collected into a DICOM Key Object Selection (KOS) document with digital signatures. The digital signature was implemented by RSA public-key cryptography combined with a public-key health certificate and health professional card (HPC) to digitally sign a series of DICOM images. Our method includes the DICOM Modality Performed Procedure Steps (MPPS) mechanism that assures the image transmission completeness and accuracy in an image examination workflow. The results show that the method is more efficient and requires less loading time to create the technician’s signature in an imaging examination workflow.
