The University of Texas Health Science Center, Houston34 enrolled

Overview

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.

Outcomes

Primary Outcomes

Image quality of conventional grid versus SimGrid using 5 point Likert scale

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.

Time frame: baseline

Image quality of non-grid versus SimGrid using 5 point Likert scale

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.

Time frame: baseline
