Characterization of the applicators, of the thermometers and of the cooling (bolus) system of hyperthermic apparatus must be made before starting hyperthermic treatment and also starting with a frequency depending on the technical features of equipments that make up the whole system. This data gives the radiotherapist some useful parameters for the selection of applicators and general knowledge of the accuracy of the system.
A computerized system with automatic treatment parameters control for radiological hyperthermia, called Sapic SV03, is presented. The system has been planned and built by the "Sezione Avionica ed Equipaggiamenti" of the Aeritalia in cooperation with the Radiotherapy Department of the University of Turin. The device is supplied with a multifrequency generator system (915, 433, 2-30 MHz) connected with many kinds of applicators, with a fiber optic system for temperature control and a previsional thermometry system. In this paper the authors presented three new applicators. The first one is a concave parallel microstrip applicator at 433 MHz, with a size 16 x 9 cm; the heating pattern is homogenous until 4 cm of depth. This antenna can be used for the treatment of chest wall recurrences of breast cancer. The second is a 27 MHz inductive ring and the third applicator is a pyramidal antenna ("TEM line") that operates at a frequency around 27 MHz.

An evaluation is made of the radiological diagnosis techniques used in the classification of renal traumas. Attention is primarily directed to arteriographical pictures, since it is felt that this examination is the most meaningful for the purposes of precise classification, above all as the prelude to possible surgery. Some cases of varying degrees of seriousness are illustrated, including one of contusion in a "pancake" kidney.
