Newborn Torso for X-Ray CT, US
The Newborn Torso phantom was developed in collaboration with the Sonographic Clinical Assessment of the Newborn Training Program at the University of Calgary. This phantom is an deal tool for Ultrasound-guided procedures, such as catheter insertion through the umbilical cord and bladder catheterization. It is constructed with realistic tissue-mimicking materials suitable for Ultrasound and X-Ray/CT imaging.
The design of our standard newborn torso phantom is based on an average newborn torso. It is made from realistic tissue–mimicking materials with ultrasound speckles suitable for Ultrasound and X-Ray/CT imaging methods. The phantom has a water-fillable umbilical cord and bladder, which can both be used for catheterization training under ultrasound guidance.
The phantom was developed in collaboration with a group of physician experts from the Sonographic Clinical Assessment of the Newborn (SCAN) Training Program program at the University of Calgary (Department of Pediatrics).
