Exam 8: Picture Archiving and Communication Systems

Which of the following is another type of network based on TCP/IP and used within a single organization, such as the radiology department?

A(n) ____ is the element that reduces the size of the image file, and is therefore a very important variable in studies examining the effects of image compression on image quality.

Two types of RIS/HIS integration schemes are available: one is brokerless and the other one uses a broker and is the preferred and default method.

For the management and care of patients, PACS have been implemented largely in hospitals and clinics where health care and medical information are the primary focus. These systems can also be used for teaching and ____________________ purposes.

A(n) ____ is a router, a computer, or even a small network containing routes and computers that is used to connect two networks to provide security.

Some digital X-ray imaging modalities, as well as MRI, generate very large amounts of digital images that result in what has been referred to as a data explosion.

The ultimate goal of workflow is to improve patient care and the efficiency of various processes, from patient registration and image acquisition to report generation, archiving, and image/report distribution throughout the health care enterprise.

Privacy, authentication, and integrity are vital security concerns surrounding an electronic radiology department.

An individual device is referred to as a node, and the connections among nodes are called ____________________.

These definitions imply that PACS is a digital radiology computer-based system or medical device where images acquired from a patient are displayed on monitors for viewing and subsequent digital image ____________________.

The PACS is concerned primarily with image data, and the RIS deals with textual data such as patient demographics.

To be a part of a PACS, image ____________________ modalities must be digital in nature.

At low ____________________ ratios (8:1 or less), the loss of image quality is such that the image is still visually acceptable.

In the digital imaging environment, one of the central means of addressing this particular challenge requires the use of a(n) ____________________ archiving and communication systems.

What is the data transfer rate of the network called?

____________________ communication involves two devices, one called a user and the other a provider.

____, as defined by IHE, are information systems or components of information systems that produce, manage, or act on information associated with operational activities in the enterprise.

The lack of PACS interfacing to information systems such as radiology information systems (RIS) and hospital information systems (HIS) resulted in ____________________ problems, such as the delivery of data to specific locations at specific times, a function carried out by technologists in a film-based imaging department.

Communication and integration of all of the ____ components require the use of communication protocol standards.

The purpose of IHE is to ensure that all digital imaging systems and information systems from different vendors can communicate with each other using communication standards to integrate all ____________________ clinical information for the purpose of viewing such information collectively.
