3D in-utero ultrasound volume of a healthy fetus at 12 weeks gestation, imaged as part of the PRECISE study. RealisticVue™ and CrystalVue™ rendering have been applied. The volume is sectioned in the coronal plane to visualise internal structures. Moving in a dorsal-ventral direction through the volume, structures such as the kidneys can be recognised. At 0:13, CrystalVue™ complexity is increased, making structures more see-through to enable visualisation of the stomach, lungs, liver and diaphragm. Image credit: H. Shah, unpublished data.
