Die Extension US (Ultraschall) ermöglicht das Erfassen relevanter DICOM-Tags, um Rückschlüsse über die Bildgewinnung ziehen zu können. Die Informationen über die Eigenschaften des Schallkopfes sowie der Ultraschallfarbe liegen in den entsprechenden DICOM-Tags vor. Achtung: Die Codes für den Schallkopftyp müssen zwingend mit einem Unterstrich zwischen den Worten bezeichnet werden, auch wenn diese im Header nicht unbedingt so vorliegen!

Relevante DICOM-Tags:

• Schallkopftyp (Transducer Type, [0018,6031])
• Schallkopffrequenz (Transducer Frequency, [0018,6011] –> [0018,6030]) in kHz
• Impulsfolgefrequenz (Pulse Repetition Frequency, [0018,6011] –> [0018,6032]) in Hz
• Ultraschallfarbe (Ultrasound Color Data Present, [0028,0014])
