Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the reliability of the techniques we will focus on the interobserver agreements. We will score the images on the following 5 specific hemodynamic parameters, tailored to the specific characteristics of the devices. To explore the validity of the techniques we will compare the differences in images of good versus sparse blood flow in terms of the same parameter. | — |
Secondary
| Measure | Time frame |
|---|---|
| To technical compare the four imaging modalities in terms of resolution, imaging depth and field of view. | — |
