Full-field digital mammography, is a type of mammography in which solid-state detectors that turn X-rays into electrical signals take the place of the traditional X-ray film. They resemble the detectors used in digital cameras. Like traditional mammograms, the electrical signals are utilized to create images of the breast viewed on a computer screen or printed on the specialized film.

A digital mammography is substantially equivalent to a traditional film screen mammogram from the patient's perspective. With Stanford's all-digital mammography, resolution and contrast can be enhanced by digitally altering the image. The improved image clarity enhances interpretation, makes seeing tiny tumors and dense breast tissue simpler, and frequently avoids further follow-up imaging.

Product Details

The product is a model of digital mammography equipment with an amorphous silicon detector measuring 24*30cm called the SN Navigator DR Care mammography. It is the most widely used type of digital mammography due to the superior imaging capabilities of A-si materials and steady quality in most environments.

Features

• High picture resolution is made possible by A-si materials in flat panel detectors.

• A high-end IAE X-ray tube chosen with Mo/W target ISO rotation centre C-arm from -135° to 180 ° reduces the time needed to modify body position.

• Multiple levels of flexible compression ensure patients' safety and comfort.

• Designs that stand-alone appear more elegant.

• Good DQE ensures high-quality emission of specific low-radiation dose images.

• Any environment, even one with a harsh atmosphere, can use it.

Advantages of using this digital mammogram machine

• Accuracy rate

In women 50 years of age and younger, digital mammography can identify up to 28 per cent more malignancies than film mammography. This also happens with women in the pre-and premenopausal stage, and women with thick breast tissue. A 28 per cent improvement in accuracy translates into earlier discovery and, more significantly, a higher likelihood of treatment.

• Diagnostic versus screening mammography

General X-ray of the breasts is performed during screening mammography to check for any anomalies. A woman can get a mammography screening even if she exhibits no symptoms. Diagnostic mammogram is conducted when a patient exhibits focused symptoms and develops a lump, or the radiologist contacts her following screening mammography.

• Computer-assisted detection

A digitized mammographic image, which can be obtained from traditional film mammography or a digitally captured mammogram, is what computer-aided detection (CAD) systems employ. Following that, the computer program looks for abnormal density, bulk, or calcification areas that might point to cancer. The CAD system highlights these areas in the pictures, alerting the radiologist to the need for additional investigation.

Enhanced ease of picture access, transmission, retrieval, and storage, as well as a reduced average radiation dosage without sacrificing diagnostic precision, are further benefits of digital mammography over film mammography. Additionally, digital mammograms are less likely to be misplaced than film mammography. The radiation exposure needed for a digital mammogram is roughly one-quarter that of a film mammogram. Film mammography's dose, however, is fairly minimal and does not significantly endanger the patients.

• A more effective process because the photographs are immediately available on the computer.
• Fewer retakes are required due to the ability to quickly view the image on a monitor in the room and move patients if necessary.
• Even for larger breasts, the digital detector produces sharp images.
• To a centralized place for diagnosis, it is simple to electronically upload images (utilizing Picture Archiving and Communications System – PACS)
• easy picture analysis
• Less radiation is emitted than with analogue systems by 30–40%.
• earlier cancer detection, even in those with thicker breasts
• It integrates seamlessly with CAD devices.

Risks

• The risk of developing cancer from excessive radiation exposure is always small. However, the advantage of a precise diagnosis far outweighs the risk due to the low radiation dose employed in medical imaging.
• Different radiation doses are used. For additional information on radiation exposure, visit the Radiation Dose in X-Ray and CT Exams page.
• False Positive Breast Imaging. Five to fifteen per cent of screening mammography need extra testing, such as ultrasonography or repeat mammograms. The majority of these tests come out clean. A biopsy or other testing may be necessary if there is an aberrant discovery.
  The majority of the biopsies show no evidence of malignancy. Women who receive yearly mammograms between the ages of 40 and 49 is thought to have a 30% probability of experiencing false-positive mammography. This happens at some point in that decade and a 7–8% likelihood of undergoing a breast biopsy during that time.

Conclusion

Generally, digital mammography is an advanced kind of screening that gives the ability to identify breast disease. This is because of its better ability to absorb x-ray photons, greater contrast resolution across a wider dynamic range in dense breast tissue, and electronic archiving of breast studies. Examine the benefits and drawbacks of each mammography machine type against their needs before deciding. The central message is that one should aim for a digital mammography machine if they have a good budget.

Even though analogue may be marginally less expensive to buy and maintain, this is less and less true each year as digital becomes the standard. Buyers will probably need a CR with an analogue, which adds another piece of equipment to buy and maintain. One of the most common disadvantages of choosing a digital mammogram machine is that it is too expensive. However, this is a small concern given that the advantages of this machine outdo its cost by saving many lives in the process.
