Radiotherapy Staff in the years ‘70

A day in 1978

In spite of intensive preventive maintenance and quality checks, the linear accelerators now and then broke down unexpectedly. Vulnerable or instable parts in the recently developed complex equipment were an important cause of failure and interruption of the functioning. This would cause a "peak hour" at the front desk; patient appointments have to be cancelled and rescheduled. From left to right: at the telephone Lia de Vries and Nannette van Drevelt, standing Marion Verhoef, Marielle Stuyt and Nelleke Hoogendam

1980ca reunie Meerten vd Laarse en partners.jpg



A private chat during a party in the department of radiotherapy. At the left side physicist Harm Meertens (appointed in 1975) and his wife Sietske. At the right side physicist Rob van der Laarse (appointed in 1969) and his wife Lia.  


Harm Meertens was responsible for the treatment equipment. During the years '70 he was closely involved in the development and introduction in the Netherlands Cancer Institute of the first afterloading equipment from Nucletron. In the years '80 he was working on portal imaging and started the development of the EPID (Electronic Portal Imaging Device).  

Rob van der Laarse was responsible for the treatment planning calculations and dosimetry. In 1974 he is appointed head of the radiotherapy physics and technical group, as successor of Herbert Marcuse who became head of the department of Nuclear Medicine. Rob developed software for the planning of megavoltage photon and electron treatments and brachytherapy, and introduced his treatment planning software first on a main frame computer of the University of Amsterdam, later on a PDP 11 in the Radiotherapy Department, and after that on a PC platform.

Engineers have fun when working on a big job.

In order to stop the increasing number of break downs, engineers Wim Simons and Rein Helmink completely replace the electric wiring of the patient couch of the Rotterdam simulator.

Instrument makers Leo de Mooy (l) and Peter Grootte (r) in their workshop on the 1st floor of building D, Radiotherapy.

Here they are seen working at the production of light weight, carbon fibre reinforced accessories for radiotherapy. The production tools as well as the first generation of these radiation transparant accessories are developed and manufactured by the physics and technical group of the department of radiotherapy.
