- The combination of microwave-induced (2450 MHz) hyperthermia and ionizing radiation was used in 7 patients with superficial malignant tumours, which were considered refractory to other therapy. A newly developed heating system was used, allowing for a maintained temperature at the master probe of 42.5 degrees C +/- 0.5 degrees C during 45 min, but temperature measurements at multiple sites showed a marked variation. This preliminary series indicates that the combination of hyperthermia and ionizing radiation may be useful, the response rate (complete or partial) being 8 of 8 evaluable lesions. Even previously heavily irradiated sites responded. Technical improvements are highly needed to allow for controlled heating of any tissue volume.

- In order to induce local hyperthermia in superficial tumours a computer system using a 2,450 MHz microwave generator connected to a circular (diameter 90 mm) direct contact applicator was constructed based on invasive temperature control. Small thermistor probes with a diameter of 0.6 mm are inserted in the tumour and surrounding tissues. Eight thermistors can be used simultaneously and one of them is chosen as the "master'. The automatic control system used a pulsed irradiation technique to avoid the problem with interactions between the metallic wires of the temperature probe and the electromagnetic field. With the system it was possible to control the temperature at the master thermistor within +/- 0.5 degrees C from the preset value.

Konferensbidrag (refereegranskat)abstract
- This paper will discuss a unified digital image distribution and processing system linking various digital image sources through a broadband local area network and a comnon image format. Ultimately, the system allows for viewing and processing of all images produced within the complex, and for viewing stations at any number of convenient locations. The physical handling of storage media at image sources, can be totally eliminated. Complete archiving, file maintenance and large scale processing capabilities are provided by a central file server. This paper presents a concrete proposal for an initial system which has a central archiving facility for permanently storing and selectively viewing computed tomography (CT), nuclear medicine (NM) and ultrasound (US) images. The system proposed can then be slowly expanded to include all the digital images produced by the radiology the department, and ultimately to include all the images by digitizing those produced in an analog fashion.
