研究概览
简要总结
The purpose of this research study is to learn if a new imaging processing technique called Simulated grid (SimGrid™) will help in getting better quality X-ray images in obese subjects. The GM85 digital radiography machine will be used to obtain X-ray images.

结局指标
主要结局
Image quality of conventional grid versus SimGrid using 5 point Likert scale
时间窗: baseline
Relative image quality will be assessed using a 5 point Likert scale ranging from -2 to +2 with -2 indicating better image quality with conventional grid and +2 indicating better image quality with SimGrid.
Image quality of non-grid versus SimGrid using 5 point Likert scale
时间窗: baseline
Relative image quality will be assessed using a 5 point Likert scale ranging from -2 to +2 with -2 indicating better image quality with non-grid and +2 indicating better image quality with SimGrid.
