Framework to semi-automatically generate masks for LV muscle. Reference images (Cref, Tref) are automatically selected from the control {Cj} and tagged {Tj} images. The reference images are manually segmented to generate masks (MCref, MTref). Control and tagged images are then registered to their respective reference images to generate displacement fields. The reference masks are warped using the displacement fields ({DCref->Cj}, {DTref->Tj}) to generate masks ({MCj}, {MTj}) for each control and tagged image. These masks along with the control and tagged images are used for ASL analysis to generate MBF maps.
