Background: In the telemedicine process, using digital techniques in disease diagnosis caused to have felt needs of archiving and storing patient information and high bandwidth in data transfer.

Methods: This study aimed at introducing an efficient way of multi-stage compression of mammographic image data based LM algorithm and artificial neural networks. At First, data derived from mammographic images given to multi-layer neural network has achieved the possibility of forming with minimum damage and  high degree of compaction in the first layer.

Results: The compression process of the mammography images was implemented using images of 128 women aged 46.41±6.55 yrs with BMI 36.78 ±5.5 from three specialized clinics in Sabzevar. The analysis yielded a mean square error (MSE) of 4.24 with the highest difference ratio of 33.46 and compression ratio of 8: 1in the output of the algorithm. The system performance based on the accurate design of the software was acceptable therefore; it demonstrated high efficiency in practice. 


Conclusion: The diagnosis in the discovery stage is highly consistent with the diagnosis in real based on reliability of software output in the compression and release, and considering the fact of mammographic images are not completely degraded during compression; therefore, this system has the capacity to be implemented achieving mammography images in hospitals and justify its application.
