Assignee:

DATCARD SYSTEMS, INC. - Irvine CA

International Classification:

G06F 21/24

US Classification:

713189, 726 30

Abstract:

Digital image storage and management systems capable of producing encrypted DICOM volumes on different types of media (e.g., Blu-ray, CD, DVD, memory stick, USB flash drive, etc.), with or without the automatic generation of labels, systems and mechanisms to generate and manage passwords for the encrypted volumes, and systems and mechanisms to manage access to encrypted data on such volumes are disclosed. Generated encrypted DICOM volumes, which can comprise confidential patient data, can be securely interchanged, archived, and distributed to users. The disclosed systems and methods can permit authorized users to access encrypted data, even if the users do not have access to the original encryption mechanism. Encrypted data stored on the volume can be easily and securely accessed by a variety of authorized users.

Abstract:

A method for attenuating coherent and incoherent noise in seismic signal data is provided. Seismic signal data is transformed from a time-space domain using a Radon-transform domain. In the Radon-transform domain, coherent noise is attenuated by muting and incoherent noise is attenuated by diversity stacking. Data remaining in the Radon-transform domain in transformed back to the time-space domain by an inverse Radon transform.
