Injury Due to Foreign Object Accidentally Left in Body During Surgical Operation
Conditions
Brief summary
Surgical sponges can be accidentally left inside patient's bodies. We are working on special tags (called microfabricated tags) that surgeons can put on their sponges. Then, if the surgeons forget to remove a sponge from a patient, they'll be able to detect these special tags in an x-ray.
Detailed description
Surgical sponges can be accidentally left inside patient's bodies. We are working on special tags (called microfabricated tags) that surgeons can put on their sponges. Then, if the surgeons forget to remove a sponge from a patient, they'll be able to detect these special tags in an x-ray. We wish to take x-rays of healthy people's abdomens with microfabricated tags lying on them. The x-rays will help us improve our system for detecting sponges left inside people's bodies.
Interventions
RADIATIONAbdominal radiographs with microfabricated tags
Subjects will have 2 x-rays of their lower thorax/ abdomen taken. For each x-ray, a microfabricated tag or no tag will be placed in a different position. The x-rays will take approximately 15 minutes to complete.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Validate the CAD (computer aided detection) system | 3 years | X-rays of the microfabricated tag will be taken. These x-rays will be reviewed and the individual tags identified manually and a control file created. The images will then be processed by the CAD (computer aided detection)system and the output will be compared to the control file. |
