The MAMMOEXPRESS mobile digital mammography unit has the potential to reduce breast cancer morbidity and mortality by improving access to screening for women in hard to reach or medically-underserved communities. With the potential to link the digital image transfer through to a specialist reporting centre, it is also an opportunity to bring subspecialty breast imaging expertise to more of the population. The MAMMOSCAN is designed with a high level of resistance to the environmental factors such as vibration, axtreme temperatures and humidity which can be experienced in a mobile facility. This provides the users with a high level of reliability that is not usually available in flat panel systems. The compact and robust design supplemented with high heat capacity X-Ray tube means that MAMMOEXPRESS is a unique offering for mobile mammography screening.
