Brief summary

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.

Inclusion criteria

* Obese adult volunteers with Body-Mass Index (BMI) exceeding 30 * subjects that require at least one X-ray for continuation of care

Design outcomes

Primary

Measure	Time frame	Description
Image quality of conventional grid versus SimGrid using 5 point Likert scale	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	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.
