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.
