Compressed Sensing SEMAC1

The CS-SEMAC technique is facilitated by the inherent sparsity of the acquired SEMAC data, since the actual distortions make up for just a small fraction of the acquired signal. Compressed Sensing SEMAC applies 8-fold undersampling of k-space in combination with an iterative reconstruction algorithm. As a result, images with very comparable diagnostic quality can be created from e.g. a six minute CS-SEMAC scan that would otherwise take approximately twelve minutes even with parallel imaging acceleration.

The MRI restrictions (if any) of the metal implant must be considered prior to patient undergoing MRI exam. MR imaging of patients with metallic implants brings specific risks. However, certain implants are approved by the governing regulatory bodies to be MR conditionally safe. For such implants, the previously mentioned warning may not be applicable. Please contact the implant manufacturer for the specific conditional information. The conditions for MR safety are the responsibility of the implant manufacturer, not of Siemens.
