HISTORICAL OVERVIEW
However, computers have been only
used in education for the last 20 years.

X-rays were discovered on 1895, by
Wilhelm Conrad Roentgen and were put
to use for medical purposes in no time.
Because of the great advances in information technology, the use of computer and
its applications especially in the medical field became inevitable. New medical
terms have been emerging combining the computer power together with medical
diagnostic procedures e.g. computed tomography and recently the computed
radiography or “CR”.
CR has been used in human medical
imaging since the 1980s
CR recently accepted in the veterinary
profession.

IT and Student Learning
For the past 20 years, a great number of research articles
worldwide were published on the implementation of
information technology in general and its effectiveness on
student learning.
It is affirmed that regardless of the teaching courses, students taught through
computer tools performed equally well as students taking a traditional course, but
required half as much time covering the same material.

Materials and Methods
1- Documenting and building a
digital database of normal x-ray
films of the adult horse.
2- Standardizing the x-ray
filming parameters of different
body parts of adult horse.
Results
Conclusion
To be used as a future
reference model.
To achieve better quality
images.
3- Proposing the requirements a
CD program for students to use
at home.
To be used for self
education and training.
4- Developing a specialized
computer program that serves
the workers in the medical field
specially Radiologists.
To review, and digitally
enhance x-ray images on
computer monitor.
5- Adapting the same program
for the internet use.
For distant teaching and
remote consultations.
