Kim, M., Yune, S., Lee, H., Lee, C., Liu, B., Li, X., Do, S., 2018. Patient- and Organ-Specific CT Radiation Dose Estimation Using AI-based BodyPart Classifier: MGH 23 Body-Part and NCICT. In Proceedings of the Society for Imaging Informatics in Medicine Annual Meeting.

Currently used solutions to measure organ specific radiation exposure during a computed tomography (CT) scan estimate radiation dose based on the predefined scan range by CT scan region. However, to reflect diverse body types, patient-specific slab selection is essential to develop precise organ dose estimation. We developed GrayNet, which is an automatic classifier for CT images that classifies body parts into 23 categories by using a deep convolutional neural network (CNN)Patient-specific radiation dose estimation method was investigated by combining GrayNet and ICRP-110 referenced National Cancer Institute dosimetry system for computed tomography (NCICT).
