Automated full-field volumetric ultrasound

An automatic full-field volumetric breast ultrasound scanner (AFFBUS) is a developing technology which was initiated to overcome the drawback of dense breast and to get a three-dimensional view of the breast.  Components scan station view station Scan station Automatic ultrasound imaging ac...

Breast imaging and the technologist

Breast screening and diagnostic programmes cannot exist without the technologists. They play an indispensable role in the acquisition of mammogram and ultrasound images  in both screening and diagnostic settings. The mammogram technologist: the primary responsibility of the "mammo tech" is the ...

Breast MRI enhancement curves

Following administration of Gadolinium there can be three possible enhancement kinetic curves for a lesion on breast MRI (these are also applied in other organs such as prostate MRI). These are sometimes termed the Kuhl enhancement curves. type I curve: progressive enhancement pattern typicall...

Contrast enhanced mammography

Contrast enhanced mammography (CEM) is a complementary breast imaging modality. A finite number of sequential images are obtained with X-ray beam produced at a high energy, above the K-edge of Iodine, and with an intravenous non-ionic Iodine contrast agent  injected between pre and post contrast...
Article

Dual-energy mammography

Dual-energy digital mammography is a complementary breast imaging modality. The technique consists of high-energy and low-energy digital mammograms after administration of iodinated contrast agent. Breast is exposed to low- and high-energy X-ray beams during a single breast compression in MLO ...

Eklund technique

Eklund modified compression technique  is a technique which can be used for patients with augmented or reconstructed breasts post mastectomy.  Technique It consists of postero-superior displacement of the implants simultaneously to an anterior traction of the breast, pushing the implants towar...

Flying focus tomosynthesis

Flying focus is a technology of image acquisition in digital breast tomosynthesis characterized by a continuous sweep during shooting. Sharpness in digital systems is determined by the modulation transfer function (MTF), which determine contrast transfer as a function of spatial frequency. Sin...
