compression of the breast is one of the essential parameters to achieve an ideal imaging quality in mammography. The test set consists of a foam cube featuring pre-defined size and density, electronic scales to fit the bucky, and a tape measure. The scales with an easy-to-read LCD display are used to measure the mechanical force of the . Firm compression of the breast in screen-film mammography procedures lowers the radiation dose to patients, enhances image contrast and definition, and improves visibility of pathologic conditions. Most mammography unit compression systems have no force-level indicator. Some systems show force variations with time and others, with angle and region of .Breast compression during mammography is one of a number of essential components in the production of an optimally diagnostic mammogram. Breast compression optimises image quality and hence the visualisation of small lesions by reducing breast thickness (Barnes G, editor.

What is breast tomosynthesis? Breast tomosynthesis, also called three-dimensional (3-D) mammography and digital breast tomosynthesis (DBT), is an advanced form of breast imaging, or mammography, that uses a low-dose x-ray system and computer reconstructions to create three-dimensional images of the breasts. Breast tomosynthesis aids in the early detection .• The Collimation Assessment test procedure was simplified. • An Alignment test for screening compression paddles was added to the Collimation Alignment test procedure. • The Technologist’s Phantom Control Charts were reformatted for clarity. • Tomosynthesis Technique Chart was added.

In mammography, breast compression is applied to reduce the thickness of the breast. This results in improved image quality because tissue superposition and x-ray scatter are reduced, while it limits the required dose [1,2,3,4].In addition, with a compression paddle the breast can be kept in a fixed position, which reduces the risk of motion artefacts and image .

However, that rate should return to acceptable .
Spot compression is also known as compression mammogram, spot view, cone views, or focal compression views. All mammograms involve compression of the breast. Spot views apply the compression to a smaller area of tissue using a small compression plate or cone. By applying compression to only a specific area of the breast, the effective pressure .The amount of breast compression that is applied during mammography potentially influences image quality and the discomfort experienced.
