48、rers Association FOREWORD The Digital Imaging and Communications in Security (DICOS) standard, this standards publication, is formally designated as NEMA IIC 1 v02. NEMA IIC 1 v02 is inspired by, and relies heavily on, elements of Digital Imaging and Communications in Medicine (DICOM). NEMA IIC 1 v0
49、2 adapts DICOM as necessary for security screening applications. While NEMA IIC 1 v02 is retained as the formal standard designation, NEMA IIC 1 v02 is referenced informally as DICOS v02. The previous edition of DICOS v02, designated as DICOS v01, was published in 2010. NOTEThe users attention is called to the possibility that compliance with this standard could require use of an invention covered by patent rights. By publication of this standard, no position is taken with respect to the validity of any such claim(s) or of any patent rights in connection therewith. If a
