Craniofacial Image Analysis Laboratory (CranIAL)

Overview

Craniofacial Image Analysis Lab at Seattle Children’s Hospital (CranIAL) aims to utilize state-of-the-art image analysis and computer visualization techniques in craniofacial research to improve our understanding of craniofacial disease processes and to assess surgical outcomes. As an interdisciplinary research team, we are dedicated to improving patient care by combining clinical expertise and data-driven research.

CranIAL maintains a growing image database as part of a remote platform that enables a collaborative research environment.  In addition to open source tools and off-the-shelf programs, we design and develop custom software to analyze and quantify craniofacial morphologic differences.  Lab members gain experience in latest image analysis software and develop critical skills in clinical research.

With a wide range of research projects focusing on different surgical techniques and craniofacial conditions, we have two unifying goals: 1) to develop novel measurements to describe complex or subtle shape differences in craniofacial anatomy, 2) to model the interactions between clinical variables (e.g. patient age, diagnosis, surgical intervention) and changes in craniofacial morphology.
