A novel method is presented allowing improving 3D-MRI. Virtual coil deconvolution imaging for effective density weighted imaging (VIDED) combines the virtual coil concept with density weighted imaging. DW imaging allows improving the spatial response function at an optimal signal-to-noise ratio but at the expense of incoherent aliasing. In VIDED imaging this aliasing is suppressed by virtual coil deconvolution imaging which is a method allowing parallel imaging even for single receiver coils. VIDED imaging was applied in slice direction of 3D-MRI improving the slice profile, increasing the SNR up to 17% and the FOV in slice direction approximately by 25%.
