[Technical aspects of the use of ultrasound diagnosis in surgical interventions].

The following are the specifications for intraoperative sonography equipment: Small, easy-to-manipulate 7-10 mHz probes which can be gas-sterilised. The sound head contact surface should be 2 X 3 X 1 to 2 cm. Three probes of different shape. Transmission cable 2-3 m in length. Gas-sterilisable ultrasound unit, cable and plug. Large screen monitor. Control panel which can be encased with a plastic foil according to sterility requirements. 8 step gray scale. Integrated image storage. Documentation possibility using videotape and/or photographic unit. For intraoperative sonography the body parts to be examined are sonographed at a distance of 1-2 cm using a precursor water gap. Interpretation of sonographic images can be performed only in connection with the palpation findings of the surgeon.
