Combison 100 Kretztechnik

Combison 100 Kretztechnik

Prototype of the COMBISON 100, the worlds first real-time sector scanner, around 1976.

COMBISON 100, serial design as it was presented in 1977 in Vienna at the second three-country meeting for ultrasound.

 

Combison 100-5 Kretztechnik

COMBISON 100-5, 1981 – 1983. The difference to C 100 is that this model has three transducer plugs.

 

Combison 111s Kretztechnik

Combison 111 Kretztechnik

COMBISON 111s, same as C 111 but with three transducer connectors. In this case there is a 35 mm camera for documentation.

COMBISON 111, improved version of C 100 and C 100-5. New feature is the keyboard for patient data entry. From 1983 – 1985. Documentation with Polaroid camera.

COMBISON 400 Series

COMBISON 410 SAT KretzTechnik

Combison 410  KretzTechnik

COMBISON 410 SAT (satellite) was developed to be connected to a basic C 410 system. This way the examination rooms of a private Ob/Gyn clinic could be separated: One room with the gynecological chair and the C 410 SAT unit, the other room with a bed for Ob exams and the system C 410, connected via cable to the SAT. Advantage: Cost of only one fully equipped ultrasound system (e.g. only one printer, probes are compatible).

COMBISON 410, a mid-range b/w and color system. Launched in 1993. Electronic arrays and mechanical sector and annular arrays possible.

 

COMBISON 410 S/L  KretzTechnik

COMBISON 410 S/L, sector and linear ultrasound system,1993.

 

Combison/SonoAce models KretzTechnik

Combison models KretzTechnik

Again COMBISON 410 and several types of SonoAce systems from the later 80s and 90s. Real-time ultrasound systems (different COMBISON models) lined up.
