The high efficiency of radiotherapy puts the highest demands on service and quality equipment. Radiotherapy with high radiation performance currently requires a precise therapy plan to eliminate errors in the chosen radiotherapy and minimize the impact of healthy tissues on irradiation on radiotherapy devices. Therefore, UJP PRAHA as has developed a new, fully electronically controlled TERAsix X-ray simulator for precise planning, which sheds light on all the requirements for accurate radiotherapy treatment.
Professionals trained by UJP PRAHA as are ready to design and coordinate the optimal placement of the X-ray simulator in the irradiation facility. We provide complete services not only for the TERAsix simulator alone, but also for pre-installation including the technological project of the facility.
Warranty, service and maintenance
Manufacturer UJP PRAHA as provides warranty for 12 months in addition to X-ray equipment (X-ray, image amplifier, TV monitors). During the warranty period, the manufacturer pays all the costs associated with troubleshooting and troubleshooting. Of course, we offer the possibility to negotiate a service contract for the lifetime of the device.
Customer training The
manufacturer organizes complete training for TERAsix simulator users. Industry-trained professionals train the user directly on site so users can consult their specific requirements and possibly customize the simulator’s operation with the workplace already in use.
Basic technical data
TERAsix X-ray simulator is designed in accordance with internationally recognized standards and recommendations IEC 601-1 (IEC 60601-1) and IEC 601-2-29 (EN 60601-2-29).
