About

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.

Enrollment: 34 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

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

Exclusion criteria

• subject who is known to have lung disease(s) which would interfere with the interpretation of the chest radiography image
• subject who is pregnant or breastfeeding
