Fig. 3From: Precision dosimetry in yttrium-90 radioembolization through CT imaging of radiopaque microspheres in a rabbit liver modelThe average CT voxel value within post structures as a function of post diameter for the three microsphere concentrations within the CT calibration phantom: 0.5Â mg/mL, 5.0Â mg/mL, and 25.0Â mg/mL. Error bars represent the standard deviation of the voxel values within a postBack to article page
