“…For data analysis, Web-based image and data distribution, and communication in the clinical environment and public domain, each accepted radiograph (subject name and identification were covered with black tape) was digitized into the Digital Imaging and Communications in Medicine (DICOM) format by using a laser film digitizer (Array, Tokyo, Japan); furthermore, each subject's information (excluding his or her name and identification, as well as any other traceable data) was put in the DICOM header (17)(18)(19). We used the following parameters: 12 bits per pixel, optical density of 0.0 -4.0, and 100-m pixel spacing.…”

“…Recently, some researchers have noticed this problem and presented their approach to address it [15][16][17]. This thesis also addresses this problem by providing an effective approach that not only connects the existing applications to the PACS, but also improves the transmission time for fetching data.…”

Transforming medical imaging applications into collaborative PACS-based telemedical systems

One of the medical technologies distinguished for its clinical value is telemedicine.Telemedical systems provide healthcare services at any time and any where irrespective of geographical location. These systems are even more interesting when they provide collaboration among the users (e.g., teleconferencing). Nonetheless, all these systems are not practical for use in clinical workflow unless they are able to communicate with the Picture Archiving and Communications System (PACS). On the other hand, there are many medical imaging applications that are not developed as telemedical systems. A large number of them do not support collaboration and many do not communicate with the PACS and therefore cannot be directly used in clinical workflows.This thesis presents an approach based on a three-tier architecture. The architecture and the developed components within it transform medical imaging applications into collaborative, PACS-based, telemedical systems. As a result, current developed medical imaging applications that are not telemedical, do not support collaboration, and do not communicate with PACS, can be enhanced to support collaboration among a group of physicians, be accessed remotely, and be clinically useful.ii The main advantage of the proposed architecture is that it does not impose any modification to the current medical imaging applications and does not make any assumptions about the underlying architecture or operating system.

“…The Society of Computer Applications in Radiology named CAD as one out of six crucial interdisciplinary efforts necessary to overcome the problem of data and information overflow in radiology [2]. The integration of the CAD software into picture archiving and communication systems (PACS) is a central requirement and prerequisite for its efficient usage [3]. However, there is a huge gap between the number of CAD systems reported in scientific literature and those routinely used in radiological practice [4].…”

“…Insufficient CAD-PACS integration is considered a main cause of this gap [3,4], where the short comings do not only refer to the technical integration but also to software usability. Usability is defined by an ISO standard as: "The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use" (ISO 9241-11:1998, 3.1).…”

Black Box Integration of Computer-Aided Diagnosis into PACS Deserves a Second Chance: Results of a Usability Study Concerning Bone Age Assessment

et al. 2013

Usability aspects of different integration concepts for picture archiving and communication systems (PACS) and computer-aided diagnosis (CAD) were inquired on the example of BoneXpert, a program determining the skeletal age from a left hand's radiograph. CAD-PACS integration was assessed according to its levels: data, function, presentation, and context integration focusing on usability aspects. A user-based study design was selected. Statements of seven experienced radiologists using two alternative types of integration provided by BoneXpert were acquired and analyzed using a mixed-methods approach based on think-aloud records and a questionnaire. In both variants, the CAD module (BoneXpert) was easily integrated in the workflow, found comprehensible and fitting in the conceptual framework of the radiologists. Weak points of the software integration referred to data and context integration. Surprisingly, visualization of intermediate image processing states (presentation integration) was found less important as compared to efficient handling and fast computation. Seamlessly integrating CAD into the PACS without additional work steps or unnecessary interrupts and without visualizing intermediate images may considerably improve software performance and user acceptance with efforts in time.
