Introduction: We investigated if the introduction of digital radiography, with its software permitting enhancement of plain radiographs, improved inter- and intra-observer agreement in the Neer classification.
Conclusion: The introduction of digital radiography aids the improvement of Neer classification of proximal humeral fractures across all grades. With superior agreement in displacement and fracture patterns, improved communication and discussion of these injuries and similar treatment plans can be expected. This may help negate one aspect of the variability in outcome of proximal humeral shaft fractures. More complex fracture configurations continue to have difficulty in interpretation and may require further imaging analysis to conclude definitively.

This series describes how digital images are processed and how to produce higher quality images. The components of digital imaging equipment and important safety standards are also covered.After successful completion of all seven modules, participants will receive 7 CE credits and a document from the ASRT recognizing their achievement.
This module describes the characteristics of digital imaging receptors and the factors that affect their response to exposure. The image capture process for digital image receptors is explained as well as the factors that determine spatial resolution. Learn how to identify the sources of image blur and the equipment associated with digital fluoroscopic imaging systems.
This module examines the relationship between exposure indicator values, histogram analysis and automatic rescaling. Learn how exposure changes will affect the appearance of a digital image and how to evaluate a digitally acquired image to assess appropriate exposure levels. You will also learn how to locate different types of artifacts on a digital image and identify their probable causes.
This easy-to follow educational program is designed for administrators or educators who want their staff or students to stay current by learning how technology has advanced medical imaging. These interactive modules describe how digital images are processed and how to produce higher quality images. The components of digital imaging equipment and important safety standards are also covered. This package contains all seven modules, an image library, transcripts and test banks for each module.
The need to guarantee the integrity and authenticity of medical images has been recognized early. Wong et al. [57] proposed the use of digital signatures and timestamps to prevent an unauthorized modification of images already in 1995. The DICOM standard introduced the concept of digital signatures and trusted timestamps in 2001 with the addition of the first Digital Signature Profiles. These profiles enable one or more digital signatures to be applied to a complete DICOM image or parts thereof, and then to be embedded in the DICOM header, which makes sure that the digital signature is always stored and transmitted as part of the signed image or document, together with the certificate of the signer, which permits a validation of the signature by any system that receives the image. An early implementation of DICOM digital signatures is described by Riesmeier et al. [48].
A new digital signature can be affixed to each signed document (image) before the old signature expires. While theoretically possible, this approach that is not practical with large archives of image data.
Finally, there is the practical problem that most imaging modalities simply do not support digital signatures. Kroll et al. [59] proposed the use of an embedded system (i.e., a very small computer) as a gateway that receives the images from one modality, adds a digital signature to each image, and then forwards the images to the image archive.
The main problem with watermarking is, however, that is has never been standardized, so all approaches are proprietary. Furthermore, watermarking typically depends on some shared secret (e.g., a secret key) that the recipient must know in order to identify the watermark. Without such a shared secret, a malicious attacker could simply check for the presence of a watermark and modify the image until the watermark is not detectable anymore, which is essentially the same as removing a digital signature. When a shared secret is used, however, the question is how this secret can be shared between sender and receiver such that an attacker can neither read nor remove it.
In medical terms, PACS stands for Picture Archiving and Communication System. A PACS system is an efficient way to securely transport private patient medical imaging information, in contrast, to manually filing, retrieving, or physically transporting film jackets. With PACS, medical professionals can store and digitally transmit images and clinical reports for immediate use at their discretion- a significant improvement over older film-based systems. In addition, medical documents and images can be housed locally or offsite on secure servers and accessed using PACS software, workstations, or mobile devices.
Understanding PACS: The Digital Imaging Hub
PACS, or Picture Archiving and Communication System, is a comprehensive digital imaging platform. Its primary role is to acquire, store, retrieve, and distribute medical images like X-rays, MRIs, CT scans, and ultrasounds. PACS replaces traditional film-based systems.
This course provides great information on the components and functionality of digital imaging systems, including computed radiography (CR), digital radiography (DR), and picture archiving and communication systems (PACS). After you complete this course you will have a broad knowledge of the history of digital radiography, the workings of digital radiology, and the important role it plays in current radiology technology practice.
