CT Gently: Personalizing CT and CBCT Imaging for the Children

Medical imaging procedures such as computed tomography (CT) and cone-beam computed tomography (CBCT) have been widely used in the diagnosis, detection and treatments of cancers worldwide. The achieved efficiency in the clinical workflow and improved patient care come at a price of radiation doses that pose potential cancer risks to the patients, especially the children who are more susceptible to the radiation damage than the adults. To address this concern, we have newly developed an iPhone app termed CT Gently that can be used to estimate the organ doses and associated cancer risk from CT and CBCT scans based on individual anatomy and scan mode. Furthermore, the CT Gently app can generate optimized mAs and kVp settings for personalized low-dose CT and CBCT scans, essential to the children undergoing these imaging procedures. The increasing radiation exposure to the large population including millions of children necessitates the applications of personalized CT and CBCT imaging for the children as well as the adults.
