Question 1

The results of computer processing can be displayed on monitors for viewing by a human observer.What is this called?

Accepted Answer

Displaying the processed results on a monitor for human observation is considered output.

Question 2

The PACS technologist works routinely on a daily basis with digital image acquisition modalities, by producing images in the imaging room.

Accepted Answer

A PACS technologist primarily manages and supports the Picture Archiving and Communication System (PACS) for storing, retrieving, and distributing medical images, rather than producing images in the imaging room.

Question 3

____ involves the use of two major technologies, computer technology and communications technology, to solve problems in society.

Accepted Answer

The question is asking for the technology that involves both computer technology and communications technology, and the most fitting answer is information technology (IT). IT deals with the use of computers and communication systems to manage, process, and distribute information. The other answer choices, CR (computer research), DM (data management), and DR (disaster recovery), may involve computer technology, but do not necessarily involve communication technology.

Question 4

Which of the following is used to send and receive signals from computers by converting a digital signal from the computer (modulate)into an analog signal?

Accepted Answer

A modem (modulator-demodulator) converts digital signals from a computer into analog signals that can be transmitted over a telephone line or other communication channels. It also converts incoming analog signals back into digital signals that the computer can understand.

Question 5

Digital devices must be able to communicate with each other regarding images and textual information, and this function requires the use of ____.

Accepted Answer

The function described in the question requires the use of Information Technology (IT), which encompasses the hardware and software necessary for digital devices to communicate with each other. CT (Computed Tomography) and DR (Digital Radiography) are medical imaging techniques, and DF is not a relevant acronym in this context.

Question 6

Storage converts data to information that can be used by human observers to solve problems, such as diagnosing a patient's medical condition.

Accepted Answer

Storage is an essential component of the information processing cycle. It stores data in a structured and organized manner and converts it into useful information that can be used to solve problems, make decisions, and perform various tasks. Therefore, it is true that storage converts data to information that can be used by human observers to solve problems, such as diagnosing a patient's medical condition.

Question 7

Display systems in the ____ environment fall into two categories: cathode-ray tubes (CRTs)and liquid crystal displays (LCDs).

Accepted Answer

PACS (Picture Archiving and Communication System) is the image management system used in healthcare. Display systems for PACS typically fall into two categories: cathode-ray tubes (CRTs) and liquid crystal displays (LCDs). MII (Medical Information Interface) and DICOM (Digital Imaging and Communications in Medicine) are standards used for medical imaging and data exchange, while HIS (Hospital Information System) refers to the broader information management system used in healthcare settings.

Question 8

____ is a computer-based system used to collect and process data to provide its users with information needed for problem solving and decision-making.

Accepted Answer

HIS (Health Information System) is a computer-based system used to collect and process health-related data to provide its users with information needed for problem-solving and decision-making in various healthcare settings. PACS (Picture Archiving and Communication System) and EHR (Electronic Health Record) are specific types of HIS used for medical imaging and electronic patient records respectively. HIMSS (Healthcare Information and Management Systems Society) is a global organization focused on advancing healthcare technology and information.

Question 9

Security allows authorized users to have access to the information and prevents unauthorized users from accessing it.

Accepted Answer

This is a basic definition of security – it refers to the measures taken to protect information and other resources from unauthorized access. By controlling who can access information, security helps ensure that only those who need to view or use it are able to do so. This helps prevent data breaches, theft, and other types of attacks that could compromise sensitive information.

Question 10

____ refers to data entry using hardware devices such as a keyboard or a mouse, etc.

Accepted Answer

Input refers to the process of entering data into a computer using hardware devices such as a keyboard or mouse. Storage refers to the process of saving data for later use, output refers to the process of displaying or presenting data, and processing refers to the manipulation of data to produce a desired result.

Question 11

The HIS contains a vast amount of medical information, data about the patient (demographic information, for example), and, of course, other related health information such as images from medical imaging procedures.

Accepted Answer

The answer of The HIS contains a vast amount of...

Question 12

For computer applications in general, information refers to useful, meaningful, and organized data.

Accepted Answer

In computer applications, information is defined as organized, meaningful data that is useful for decision-making or analysis.

Question 13

Since the information contained in the HIS can be shared with the EHR, physicians in the hospital, for example, can access related information on their patients from their offices, if required.

Accepted Answer

The answer of Since the information contained in the HIS...

Question 14

Within a PACS environment, it is mandatory that the PACS be integrated with information systems, since these systems contain data and information related to the patient whose images are stored in the PACS.

Accepted Answer

Integrating the PACS with information systems ensures centralization of patient data, allowing for easier access to clinical information and improving patient care.

Question 15

Digital imaging technologists are beginning to play an important role in image post-processing, imaging research, and publishing ventures.

Accepted Answer

The answer of Digital imaging technologists are beginning to play...

Question 16

____ is a computer-based system for storing and transmitting images to remote locations for use by others involved in the medical management of the patient.

Accepted Answer

DICOM (Digital Imaging and Communications in Medicine) is a standard used for transmitting medical images, while PACS (Picture Archiving and Communication System) is a computer-based system used for storing and sharing medical images. Therefore, the best choice is option D, PACS.

Question 17

____ deals with the structure and function of a computer, and how it can be used to solve problems.

Accepted Answer

Computer technology deals with the structure and function of a computer and how it can be used to solve problems. Information technology, imaging informatics, and communications technology are related fields, but do not specifically address the structure and function of a computer in the same way that computer technology does.

Question 18

Hardware is the physical components used to process data and software is the computer programs that direct all hardware components to solve problems and thus derive useful practical solutions.

Accepted Answer

This is an accurate description of the difference between hardware and software.

Question 19

The informatics infrastructure and knowledge-base management section address the use of software tools to manage image processing and visualization, communications, graphical user interface, and data and knowledge.

Accepted Answer

The answer of The informatics infrastructure and knowledge-base management section...

Question 20

____ refers to the process of changing data to information, and therefore, computers and communications technologies are central elements to the process.

Accepted Answer

Informatics refers to the combination of information technology, computer science, and data analytics to convert data into meaningful information. Computers and communications technologies play a vital role in the process of converting data to information. Networking, protocols, and security are all important components of informatics, but they do not fully capture the overall process of converting data to information.
