Conventional Mammography

Mammography is the basis of the technique used, change in density between the soft tissues that make up the breast, x-ray beam is based on the different absorption. Low-energy X-rays and obtained by applying a special compression technique for radiography. Radiation-induced breast cancer risk as much as possible should be given a low dose (93). Mammography units in the last 15 years, film screen image receptor, the movie is very important changes occurred in the process, and radiographic technique. Radiographs, mammogram quality of the radiation dose increased, and the patient also decreased significantly. Screen film mammography radiation dose combinations allows the reduction, reduces radiation dose by 30-50%.

Conventional mammography, general features.


a) It's cheap.

b) when combined with the screen (together), the image is quite successful in creating

c) 17-20 line pairs per milliliter has the ability to analyze, this feature is the ability of superior information in storage.

Disadvantages:

a) Films, both the detector and the imaging environment. Spacial contrast and resolution of technical factors of the film and into the bathroom in them directly affects the value of the irreversible problems, as reflected in the data.

b) Contrast resolution is lower than the digital method.

c) After the formation of the image can not be changed once. This is also compatible with the structure of the breast in the optimal conditions for exposure properties requires that a limitation is that all this creates in terms of selection of the appropriate window setting.
