Question 1

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 (Picture Archiving and Communication System) technologist primarily manages and ensures the proper storage, retrieval, and distribution of medical images within the digital system, rather than producing images in the imaging room.

Question 2

____ 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 are more specific and focus on different aspects of technology.

Question 3

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

Accepted Answer

The use of computer technology and communications technology to solve problems in society falls under the category of Information Technology (IT). Therefore, choice D is the best answer.

Question 4

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

Accepted Answer

Security is all about ensuring authorized access and preventing unauthorized access.

Question 5

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

Integration with information systems is necessary for accessing patient data and information associated with the stored images in a PACS.

Question 6

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 7

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 8

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 9

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 10

____ 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 (Hospital Information System) is a computer-based system used to collect and process data to provide its users with information needed for problem solving and decision-making. PACS (Picture Archiving and Communication System) is used for managing medical images, while EHR (Electronic Health Record) is a digital version of a patient's paper chart. HIMSS (Healthcare Information and Management Systems Society) is a global organization that promotes the use of information technology in the healthcare industry.

Question 11

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 Systems) is the environment where display systems are used to view medical images. The two categories of display systems in PACS are CRTs and LCDs.

Question 12

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 is a device that modulates and demodulates digital signals to allow computers to communicate over a telephone line or cable. It converts digital signals from the computer into an analog signal that can travel over telephone lines, and then converts the analog signal back into a digital signal at the receiving end.

Question 13

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

Accepted Answer

Output refers to the results of computer processing that can be displayed on monitors for viewing by a human observer.

Question 14

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

Accepted Answer

The process described refers to the field of informatics, which involves the use of computers and communications technologies to acquire, store, process, and analyze data, and transform it into meaningful information. Networking, protocols, and security are all important components of informatics, but they do not fully capture the breadth of the field.

Question 15

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 holds data that can be analyzed into useful information for making decisions or solving problems. For example, a doctor may store patient data such as medical history, test results, and symptoms to diagnose a medical condition.

Question 16

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

Accepted Answer

Information is defined as useful, meaningful, and organized data in computer applications.

Question 17

____ 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

PACS (Picture Archiving and Communication System) is specifically designed for storing and transmitting images to remote locations for use by other healthcare professionals involved in the medical management of the patient. MII (Medical Image Interpretation) is not a commonly used acronym in the healthcare industry, RIS (Radiology Information System) stores and manages radiology imaging data but does not transmit images, and DICOM (Digital Imaging and Communications in Medicine) is a standard for exchanging medical images and related information but is not a system for storing and transmitting images.

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 statement is true. Hardware refers to the physical components of a computer such as the CPU, RAM, hard drive, and motherboard, while software refers to the programs and operating systems that run on the computer and enable it to perform specific tasks. The software instructs the hardware to process data and solve problems.

Question 19

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 requires the use of Information Technology (IT), which refers to the use of computer systems, software, and communication technologies to process, store, and transmit data. CT (Computerized Tomography) refers to a medical imaging technology, DF (Data Format) is a generic term and DR (Digital Radiography) is a specific medical imaging technology.

Question 20

____ 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 system using hardware devices such as a keyboard, mouse, scanner, or touch screen, etc.
