结局指标
主要结局
Correlation of body weight with the variation coefficient (image noise).
时间窗: 360 seconds
The image noise will be measured by VOI (Volume Of Interest) in the images. The units of measure will be kilograms (kg) for body weight, and percentage for the variation coefficient.
次要结局
- Correlation of dose-regimen with the variation coefficient (image noise).(360 seconds)
- Correlation of acquisition protocol time with the variation coefficient (image noise).(360 seconds)
