In the early sixties Libero Bonetti has started a strict collaboration with the Radiology Institute of Bologna University , then directed by the Prof. Palmieri, that caused the realization of injector tire for angiography and cardiology; this collaboration is afterward prosecuted with the realization of an equipment for arteriography, which allowed the exposure of 6 sheets radiographics of large format (cm 30 x 120) in rapid sequence.

In the early seventies Libero Bonetti was engaged in the planning and production of different electromedical devices. The principal devices were:

• C-arm portable for fluoroscopy
• r emote controlled board;
• injectors for contrast media for angiography.

Between 1975 and 1980, due to the success of the radiological instruments, S.I.A.S. solely devoted itself to the electromedical field. S.I.A.S abandoned all production of research equipment for other fields that were not medical. In short, in 1982 S.I.A.S. went into partnership with S.p.A to develop the business further by focusing on development, production, marketing, installation and maintenance of medical equipment/devices. The company's vision emphasizes the development of high quality, innovative medical devices/equipment
The company policy is strongly directed to development of innovative medical devices and of high quality.
For this reason, the planning and development of the medical devices/equipment has been made in conjunction with the various certified research institutes and clients.

As a result of the company's policy, SIAS is one of the leading manufacturers of medical devices and equipment, especially in the more advanced areas of cardiology and angiography. In particular, SIAS is the sole European manufacturer of injectors for angiography and TAC. It was also the first company in Italy to produce a mobile system for angiography and cardiology and it is the only company in the world to produce all the components base of the room for emodynamic, that is injector, bed for catheter and angiograph
