HISTORICAL OVERVIEW

 X-rays were discovered on 1895, by Wilhelm Conrad Roentgen and were put to use for medical purposes in no time.

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

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 generaland 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.

Conclusion

1- Documenting and building a digital database of normal x-ray films of the adult horse.

To be used as a future reference model.

2- Standardizing the x-ray filming parameters of different body parts of adult horse.

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.

27 normal x-ray films covering 19 different body parts

10 abnormal x-ray films of different affections

grouped into 4 main categories: head; neck and back; thoracic limb; and pelvic limb).

were added as an educational material for the students to learn from already diagnosed cases.

Radiographic parameters were included as a guide-reference. (FDD), (KV) (mAs). HDS Bucky

Advantages of using X-RAY REVIEWER:

Financial

Human error factor setting of the machine

1- No need for having multiple film Cassettes

2- No wasted time in reloading the Cassettes

3- No waiting time before dismissing the patient and working on another

4- Cost of Raw Films

High workflow and patient throughput.

1- Human error factor developing the film

2- No need for 'retake' radiographs

3- Cost of Chemicals

Hidden costs:1-Machine / components life-time

2- Power consumption

3- Labor time

4- Patients pre-medications
