Since the late twentieth century, breast cancer has become one of the most common diseases in women from 40 years of age, making it the fifth leading cause of cancer death worldwide, with a probability of 1 - 8 that the cancer is diagnosed and 1-34 to die for this cause, as indicated by the Breast Cancer Incidence and Mortality Worldwide of International Agency for Research on Cancer 2010. Mammography is the method used to detect breast cancer, allowing treatment and cure of the patient. This method uses ionizing radiation (X-rays) that has an associated radiological risk associated with the deposited in the breast tissue dose. Only one mammographic image quality allows the correct diagnosis and avoid misdiagnosis or repeated exposures to X-rays that affect the health of the patient. This paper applies the parameter of the rejection rate imaging in mammography to determine the quality of them in the mammography service of the National Institute of Neoplastic Diseases (NIND) and use this parameter as an indicator for the improvement of the Generation System Images, reducing the number of repeated images and therefore the collective dose imparted to the patient. In this thesis research, we propose and implements a new classification for rejected images, allowing locate the fault in the aforementioned system more quickly and easily, improving service Mammography INEN in their environment, equipment, personnel, etc., leading to overall achievement reducing the collective dose in 16.2% and the rate of rejection of images by 14%, placing them below the tolerance level indicated by the International Atomic Energy Agency (IAEA).
