From the X-ray sphere to Molecular MRI – Milestones along the way to integrated healthcare.
The rotating anode tubes introduced by Siemens in 1933 can withstand much greater electrical loads and were thus more efficient than their conventional counterparts. Marketed under the name Pantix, the first tubes lay the foundation for the development of modern X-ray tubes.
In 1934, Siemens introduced the X-ray sphere, which could be connected directly to domestic power supplies. With total sales of nearly 30,000 units, the system was used worldwide until the 1970s.
The different types of particle accelerators – like the Betatron of Siemens - were used to produce extremely hard X-rays and electron beams for examining materials and to administer high-energy radiotherapy in medical applications.
Siemens began pioneering work in the 1930s. The first experimental betatron accelerator, which generated six million electron volts, was produced in 1944. Subsequent series models achieved levels of up to 42 mega electron volts.
In 1953, Inge Edler, a Swedish physician, and the physicist Carl Hellmuth Hertz were intrigued by the idea of using ultrasound technology to achieve more precise heart diagnoses. Supported by Siemens in Erlangen, Germany, they were the first to use the ultrasound technique for echocardiography.
Today, this powerful ultrasound process is a standard component of all cardiovascular examinations.
In Sweden in 1958, the first cardiac pacemaker was implanted in a critically ill heart patient, who had been suffering up to 20 cardiac arrests daily. The device was developed by Elema-Schönander AB (subsequently Siemens-Elema AB) under the direction of Rune Elmquist. The surgeon Åke Senning performed the operation after previous experiments with dogs.
Vidoson is the name of the world’s first ultrasound unit for “real-time” use. It was developed by the German Siemens engineer Ralph Soldner in the 1960s. From 1967 on, the system was produced and sold in Germany.
The Vidoson made it possible to observe movements inside the body on a luminescent screen right while they were taking place. The non-invasive sound waves became especially important in obstretrics and pediatrics.
