Lister Hill National Center for Biomedical Communications

The Lister Hill National Center for Biomedical Communications
(LHNCBC) is a computer research and development division of the
National Library of Medicine. The Center was established by joint
resolution of Congress (P.L. 90-456) in 1968 and named in honor of
Senator Lister Hill, a long time proponent of national health care
and biomedical science issues. Professional staff of the Center
includes computer scientists, communications engineers, health
professions educators, and related disciplines. In addition to work
in intramural laboratories, staff also manage extramural
collaborative programs which apply new technologies to problems in
biomedical knowledge management.

In its first fifteen years of existence, the Lister Hill Center
undertook major experimental programs in the use of satellite-based
video and audio conferencing, educational program development,
support of regional health professions communications networks, and
prototype computer information systems development, including
prototyping of NLM's MEDLINE_ system. The current research and
development programs of the Center fall into three major areas:
Computer and Information Science; Biomedical Image and Communications
Engineering; and Educational Technology development.

Computer and Information Science activities focus on issues of
acquisition, representation, retrieval, and effective use of
biomedical knowledge as related to automated systems. Included are
projects designed to provide improved methods of maintaining and
retrieving information from large-scale databases, such as those
containing full-text versions of clinical practice guidelines.
Current technology has proven the utility of the "stand alone"
database. Major challenges facing systems designers today are the
conceptual and implementation issues surrounding interlinkage of
computerized information sources via natural language interfaces,
computer networks and gateways, and inter-database links using
"intelligent" thesauri and vocabulary translators. A major effort of
the Center is thus its involvement with the Unified Medical Language
SystemTM (UMLS) research project. UMLS is a multi-year research effort
to create methods which accommodate the diversity of naming systems
in the biomedical domain, and provide tools for linking and accessing
biomedical information in many different locations and varied
computer-based forms.

Another area of research and development is the use of expert system
methods to embody the factual and procedural knowledge of human
experts. The development and rigorous testing of these systems in
biomedicine and public health domains is an important activity of the
Center.

Biomedical Image and Communications Engineering: These projects focus
on that component of biomedical knowledge which is not represented by
text. In keeping with the Library's mandate to serve as an archive
and distribution center of the published literature, the imaging
research group has research projects in the use of electronic
technologies. One such project is the System for Automated
Interlibrary Loan (SAIL), which stores electronic representations of
page images on optical disk, and responds to interlibrary loan
requests by automated printing or facsimile transmission of the full
text of journal articles.

Radiological images are an important part of health care, and the
Center is devising methods for storing and transmitting large numbers
of x-ray images over the Internet, an international computer network
linking academic research centers. Other image engineering projects
focus on the use of electronic means to represent high resolution
color images of histologic sections, and the technology for depicting
skin lesions.

Educational Technologies: These projects represent a long-standing
commitment of the Center to support and develop methods for training
health care professionals. Projects have a strong audio-visual
component, and in many cases combine microcomputer technology with
videodisc-based images. The program emphasizes intramural development
and demonstration of new educational technologies, and liaison to
health professions schools and professional societies for field
testing and other collaboration. Projects are available for
demonstration at the Learning Center for Interactive Technology of
the Lister Hill Center.

The activities of the LHNCBC are carried out in its five branches:

Communications Engineering Branch

The Communications Engineering Branch conducts and sponsors research and
development in image, signal processing and communication systems and
techniques. The Branch designs, builds, and evaluates prototype systems
for various biomedical image types, including page images from the
biomedical literature and those of clinical importance, such as
radiology and histology images. Systems development includes techniques
for transmitting these images efficiently over local and wide area
digital networks.

Information Technology Branch

The Information Technology Branch designs, develops, and evaluates
prototype systems for the processing, storage and retrieval of
biomedical information, with emphasis on full-text and factual
databases. Methods for storing and delivering these information
resources via online networks, optical media such as CD-ROM, and display
of information on graphical workstations are major components of the
Branch projects.

Computer Science Branch

This Branch performs basic and applied research, including development
of prototype systems and comprehensive models, in the areas of knowledge
representation and reasoning, indexing vocabularies, natural language
understanding, artificial intelligence, expert systems, problem-solving,
and human-computer interface engineering. This involves development and
use of clinical database systems, knowledge-based systems, and
literature-based systems.

The Branch has a major research and development focus in expert systems
as applied to clinical problems such as disease diagnosis, as well as
information science problems such as optimizing the results of online
searching of MEDLINE by novice users. Frame-based and rule-based
knowledge systems are also applied to the understanding and
representation of biomedical text. Research in the new discipline of
machine learning is also underway.

Audiovisual Program Development Branch

The Audiovisual Program Development Branch creates prototype
demonstration instructional products in collaboration with other LHNCBC
branches; provides instructional design and multimedia services for the
development of proof-of-concept prototypes, and conducts research in
improved media production techniques. This Branch also provides
professional and technical multimedia expertise for all Center projects.
New technologies such as High Definition TV are evaluated for their
application to biomedical images.

Educational Technology Branch

The Educational Technology Branch conducts research and development in
computer, audiovisual, and multimedia methods for supporting health
professions education. The Branch also sponsors the creation of new
educational resources, such as the Visible Human Project, a three
dimensional image database of the x-y-z coordinates of the internal and
external structure of entire human beings. This project, begun in 1991,
will result in a digital image library of volumetric data representing
a complete normal adult human male and female. Included will be digital
representations derived from cross-sectional photographic images from
cryosectioning, computerized tomography (CT), and magnetic resonance
imaging (MRI).

The Branch operates a Learning Center for Interactive Technology which
serves as the focus for displaying new and effective applications of
educational technologies to faculties and staff of health sciences
educational institutions and other visitors. Health professions
educators are assisted in the use of educational technologies in health
sciences education through training, demonstration and consultation
activities.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
