Medical Imaging Informatics

it is the collective name given to the field of work and
combination of technologies that provide the features of a paper-less or
paper-lite department

concerned as a specialty with the
electronic acquisition, storage, and distribution of the text and image data
produced and utilized within a diagnostics department (Radiology,
Pathology, Cardiology, etc.) for the wider provision of care and benefit to
patients.

a sub-speciality of health informatics, which is itself
defined as: ‘The knowledge, skills and tools which enable information to be
collected, managed, used and shared to support the delivery of healthcare
and promote health.

Sir Wilhelm Conrad
Roentgen discovered xrays
• First image was his wife,
Ana Bertha’s hand

Roentgen received Nobel
Prize in Physics

Felix Bloch and Edward
Purcell simultaneously
and independently
developed the concept of
Nuclear Magnetic
Resonance and received
the Nobel prized in the
same year

Sir Godfrey Hounsfield
invented the first CT
scanner at EMI research
laboratories

Alan M. Cormack created
the early mathematical
models used in CT

PACS was first created by Dr. Richard J. Steckel

Hounsfield and Cormack received Nobel Prize for the
development of Computer assisted Tomography

American College of Radiology and National Electrical
Manufactures Association develop standard due to the emerging need
for transfer of medical images

First standard image was release entitled “ Digital

DIC second version was released

Third version of image was released, and the name was
change to Digital Imaging and Communication in Medicine
(DICOM)

primarily deals with medical imaging
modalities such as X-rays, CT scans, MRIs (Magnetic Resonance Imaging),
ultrasound, and more. These modalities produce visual representations of
the human body, which are crucial for diagnosing and monitoring medical
conditions.

One of the central goals of imaging
informatics is to digitize medical images. This involves
converting analog images (like traditional X-ray films) into
digital format, making them easier to store, transmit, and
analyze electronically.

systems used for managing the administrative and workflow aspects of radiology departments. They handle patient scheduling, billing, and reporting, streamlining the radiology workflow.

Imaging informatics involves integrating
medical imaging data with electronic health records (EHRs) and
other patient information systems. This integration enhances the
overall quality of patient care and allows healthcare providers to
make more informed decisions.

systems are a core component of imaging informatics. They are specialized
software and hardware solutions designed to manage and store medical
images, enabling healthcare professionals to access images electronically,
compare them over time, and share them securely with colleagues

Advanced image analysis techniques, including
computer-aided detection (CAD) and artificial intelligence (AI), are
increasingly being applied in imaging informatics to assist
radiologists in detecting and diagnosing medical conditions more
accurately and quickly

The field plays a crucial
role in telemedicine by enabling remote consultations and
diagnostics through the transmission of medical images and
reports over secure networks.

Imaging informatics supports
research efforts in medical imaging and provides tools for
education and training in the field of radiology and related
disciplines.

The management, processing,
and utilization of information have given rise to three
closely related yet distinct fields

Is the scientific study of computation and computational
systems. It involves understanding the theoretical
underpinnings of algorithms, programming languages, and
data structures.

design software, develop algorithms, and
explore the limits of what can be computed. While Computer
Science has a strong theoretical foundation, it also has
practical applications in software development, artificial
intelligence, and other technological domains.

Combines the hardware of computers and computercontrolled devices with software, operating systems,
authoring tools, expert systems, and courseware to
support trading technology.

Correlates with information technology.

Includes programming, networking, database design
and development to ensure that computers work
properly.

is a type of computer program that performs a specific personal, educational, and business function. Each application is designed to assist end-users in accomplishing a variety of tasks, which may be related to productivity, creativity, or communication.

2 MAJOR CLASSIFICATIONS OF SOFTWARE

Is a category of software that serves as the foundational
software infrastructure for a computer or computing device.

It is responsible for managing and controlling the hardware
components and providing an environment in which
application software can run.

the most
critical piece of system software. It manages hardware
resources, including the central processing unit (CPU),
memory, storage devices, and input/output (I/O) devices.
Common operating systems include Windows, macOS,
Linux, and Android.

software components that
enable the operating system to communicate with and control
hardware devices such as printers, graphics cards, network
adapters, and more. Device drivers act as intermediaries
between the hardware and the OS, ensuring proper
functionality.

is a type of software that is embedded in hardware
devices. It provides low-level control and instructions for the
hardware's operation.

Common examples of firmware

software tools that translate highlevel programming code into machine code or lower-level code
that can be executed directly by the computer's CPU. Examples
include GCC (GNU Compiler Collection) for C and C++.

execute code line by line, translating
and executing it in real-time. Languages like Python and
JavaScript often use interpreters.

convert assembly language code into
machine code. They are used for low-level programming

consists of various tools and
programs that assist in system management and
maintenance. These utilities can include disk cleanup
tools, antivirus software, backup software, and system
optimization tools.

Often referred to as "apps" or "programs," is a category of

manages the hardware andprovides a platform for applications

Microsoft Word, Google Docs,
and LibreOffice Writer are examples of word processing
applications used for creating and editing documents

Microsoft Excel, Google Sheets, and
LibreOffice Calc are spreadsheet applications used for data
analysis and calculation.

Adobe Photoshop, Adobe Premiere, and CorelDRAW are examples of software for image editing, video editing, and graphic design.

Browsers like Google Chrome, Mozilla
