Primary | Radiation attenuation in percentage (%) and in absolute terms (µSv/min) | The null hypothesis is that the XPF thyroid collar is inferior to the standard 0.5mm Pb lead equivalent thyroid collar with regard to radiation attenuation/transmission. The alternative hypothesis is that the XPF thyroid collar is non-inferior to the standard thyroid collar. If there is truly no difference between standard and XPF thyroid collars, then 60 patients are required to be 95% sure that the lower limit of a one-sided 95% confidence interval (or equivalently a 90% two-sided confidence interval) will be above the non-inferiority limit of -0.7% transmission rate and -0.013 µSv/min. | The attenuation is assessed directly after each procedure (day 1) | No |
Secondary | Wearing comfort of the XPF cap and collar on a scale from 0-100. | (day 1) Operators are asked directly after each procedure to rate the wearing comfort | No |
