摘要：Nowadays digital ultrasound-cardiovascular devices are able to send out directly digital
images and films. Thanks to the large adoption of such devices, the echocardiographic world is facing
new ways of exchanging images and collaborating. What we present in this paper is a review of
the experimental projects carried in Lombardy, meant to support the work of specialists by means
of second opinion and telemedicine services. On the medical point of view echocardiography is a
widely used activity where operators are perfectly accustomed to do repetitive operations and steps.
Tele-echocardiography (T-E) introduces new methods and technologies into stable and everyday
medical practice, causing disruptions either on the side of the specialists’ way of working or on the
new opportunities and service. Introducing such a service means to properly model it in order to reduce
the changes in the operators’ way of working while maximizing the benefits. A proper method
of modelling the operators’ needs is then a key factor which must be correctly addressed. This paper
will present some successful projects and the assessment procedure but it will also discuss a possible
service modelling method, which has been adopted for the described experiences.
