First ultrasound system and new Philips simulator in clinical practice

1980, Philips' simulator type LocSim with 9" image intensifier in the NKI.

In 1980 the first ultrasound system is acquired. It is expected that with this device tumours can be localised faster and more accurately than before. An additional advantage of an ultrasound examination is that the patient does not receive extra ionizing radiation. The radiation oncologists apply the ultrasound examinations for the planning of treatments. 

The second important purchase in 1980 is a modern radiotherapy simulator from Philips. This device replaces the Toshiba simulator from 1973. The X-ray tube and image intensifier combination of the old Toshiba simulator was not sensitive enough to make suitable images of obese patients. Also the patient support system was not strong enough. When it broke during an examination it was decided to replace the simulator ahead of schedule. Also the transversal tomograph was removed from the simulator room. The superior image quality of the CT scanner makes this device obsolete.

At the request of the Netherlands Cancer Institute some features have been added to the original Philips design.

An optical distance indicator is mounted on the X-ray collimator as is customary on linear accelerators.

Instead of a pendant controller the couch is fitted at both sides with fixed control panels, allowing the combined operation of simulator functions by two radiation therapists.
