Design outcomes

Primary

Measure	Time frame
User-friendliness of the various operating concepts (recorded via the NASA Task Load Index)	—

Secondary

Measure	Time frame
a) Usability - Measurement of the temporal efficiency of each operating concept (intervention time as incision-suture time and setup time as door-cut time) - Interventionalist satisfaction with the interventional procedure (personally perceived efficiency) and how was the time required assessed in light of the perceived complexity of the procedure (complexity vs. time) b) Patient Exposure - Comparison of patient radiation exposure based on the dose values ??provided by the CT scanner for fluoroscopic CT imaging (dose report) c) Complications - Comparison of intervention-related complications, assessed according to the CTCAE classification	—
