This work generalized direct virtual coil (DVC) using
SPIRiT kernel and generalized DVC can be used for
arbitrary sampling pattern. In the generalized DVC,
SPIRiT kernel and coil combination kernel are combined.
Sensitivity map could be also estimated from coil
combination kernel. Virtual coil data can be got through
convolution between the combined kernel and the under
sampled kspace data from all source coils. The results
of the generalized DVC are nearly the same as SPIRiT and
ESPIRiT and are better than those of DVC.
