All positioning motions of this C-arm type system are fully motorized, and synchronized for maximum patient throughput. Once the exam is selected from either the modality worklist or directly by the technologist, the QV-9000 automatically moves itself into the position required to complete the examination. The system can be easily positioned from either the digital operators control monitor or from Quantum’s unique “TechVision.” The unit features a highly versatile C-arm design which maintains constant alignment between the x-ray tube and the image receptor, regardless of C-arm rotation position or image receptor angle. This allows for a great number of exam positions, for not only average patients, but also those who are disabled or physically restricted.
Also on display is the latest feature of TechVision—complete two-way generator integration and image preview. TechVision lets technologists easily view and set-up all exposure parameters at tube-side. Technologists are given the opportunity to remain by the patient for positioning or repositioning, yet also use the Operator Control Panel outside of the room, if patients are comfortable.
The ease of two-way generator communication via TechVision eliminates the back-and-forth from the Operator Control Panel to the patient, for the system set up for patient exams. The operator has complete control to adjust exposure parameters at the tube-side. Within 6 to 9 seconds, the technologist can preview the x-ray directly on the TechVision’s in-room touch-panel monitor, mounted on the tube head assembly, enabling the technologist to determine whether the exam needs to be repeated or the technologist can move on to the next view. With TechVision integrated with the DR system, the technologist obtains another incremental productivity gain in total digital workflow. This synchronized generator solution greatly streamlines the imaging process and decreases overall examination time, while allowing the technologist to remain close to the patient, for increased patient care.
