Abstract

It is important when motion-correcting Rb-82 cardiac PET-CT scans that diaphragm motion is accounted for, to avoid attenuation-correction artifacts. In the absence of a gated CT, a model of the diaphragm could assist in identifying the diaphragm position in noisy PET images as a step towards performing respiratory-matched attenuation-correction. To test this, a shape model was constructed from a training set of 10 gated CT datasets, in which the diaphragm was segmented. Principal Component Analysis was performed on corresponding landmarks from all surfaces to extract modes of variation in shape and motion between patients.
