1. printed by www.postersession.com Plagiocephaly is a condition characterized by an asymmetrical distortion (flattening of one side) of the skull. Common in newborn babies, as a result of intrauterine environment or infant positioning after birth Common in newborn babies, as a result of intrauterine environment or infant positioning after birth Nearly 70% of all children will be screened within the 24 months of birth correlating to ~7500 screenings per day Nearly 70% of all children will be screened within the 24 months of birth correlating to ~7500 screenings per day Systonic Plagiocephaly (Premature closure of coronal structure) prevalence rate is 1/1000 babies. Requires extensive treatment such as a helmet (see below) Systonic Plagiocephaly (Premature closure of coronal structure) prevalence rate is 1/1000 babies. Requires extensive treatment such as a helmet (see below) Non- systonic Plagiocephaly prevalence rate is 1/300. May require either simple or extensive treatment. Non- systonic Plagiocephaly prevalence rate is 1/300. May require either simple or extensive treatment. Current measurement techniques use plastic calipers or similar physical methods Current measurement techniques use plastic calipers or similar physical methods Experimental Design: 10 people are given instructions on how to use the application. Each person is given a standardized photo with marked points. Application is tested 5 times by each person at 5 ratios designated by points. This is done to test the accuracy of iPhone touch screen using our markers and photo. Robinson, Shenandoah, and Mark Proctor. "Diagnosis and Management of Deformational Plagiocephaly."

The results are displayed above with an average of 1% error. The automatic version of the application with Edge detection and "snap to" features are the next step.
