In most case, packages with computers and software included are offered and installed by the companies. A printer is necessary, if printed pictures and reports are warranted. As already mentioned, the technique is applicable for a wide spectrum of medical diagnostic assessments, whereby one and the same device may be used by the different medical disciplines. Depending on the region of interest, investigators have to choose between transducers of different tissue-penetration depths. {34}

In UK, the screening equipment is purchased centrally and a technical equipment specification has been developed. The technical equipment consists of portable ultrasound machines, producing good quality black and white images, with digital recording devices from where data can easily be downloaded. The machines should be able to store and transfer data digitally. Additionally, an examination couch, wipes, a transducer and mobile computer media and devices are necessary. {5}
