Intended Use

MultiBand SENSE is a software option intended for use on Ingenia 3.0T CX MR Systems. It's indicated for use in magnetic resonance imaging of the brain for diffusion weighted imaging. MultiBand SENSE consists of an acquisition and reconstruction technique allowing simultaneous excitation of multiple volumes to accelerate imaging acquisition times, or increasing coverage or number of diffusion directions without increasing scan time.

Device Story

MultiBand SENSE is a software option for Philips Ingenia 3.0T/3.0T CX MR systems; enables simultaneous excitation/acquisition of multiple volumes/slices for spin echo and gradient echo sequences. Uses multiband RF pulses for simultaneous excitation; SENSE algorithm for image unfolding. Improves unfolding via linear phase shift over k-space in volume direction (using blip-gradients or RF pulse switching) and shifting coil sensitivity data. Incorporates B0 map information to minimize artifacts from B0 inhomogeneity. Operated by MR technicians/radiologists in clinical settings. Output is accelerated MR images; allows faster acquisition, increased coverage, or higher resolution/diffusion directions without scan time penalty. Benefits patient by reducing scan duration or improving image quality/diagnostic information.

Clinical Evidence

No clinical data. Substantial equivalence demonstrated via design features, indications for use, fundamental scientific technology, and non-clinical performance testing.

Technological Characteristics

Software option for MR systems. Uses multiband RF pulses for simultaneous volume excitation. Reconstruction utilizes SENSE algorithm with linear phase shifts (blip-gradients) and B0 inhomogeneity correction. Compatible with 32-channel head coil. Complies with IEC 62304 and ISO 14971.

Device Description: The Multiband SENSE feature enables simultaneous excitation and acquisition of multiple volumes for spin echo and gradient echo MR sequences for the purpose of speeding up acquisition times or increasing coverage or resolution without increasing scan time. The simultaneous volume excitation is achieved using a multiband RF pulse. The image unfolding of the simultaneously acquired volumes is done using the SENSE algorithm. The image unfolding is improved by introducing a shift in k-space in the phase direction which is dependent on the volume spatial location, resulting in a spatial shift of the aliased pixels. Artifacts related to mismatch between SENSE reference scan and the clinical scan are minimized using information from a previously acquired Bo map. The MultiBand SENSE feature is available on Ingenia 3.0T and Ingenia 3.0T CX systems, and is compatible with the 32 channel head coil. Indications for Use: MultiBand SENSE is a software option intended for use on Ingenia 3.0T and Ingenia 3.0T CX MR Systems. It's indicated for use in magnetic resonance imaging of the brain for BOLD fMRI and for diffusion weighted imaging. MultiBand SENSE consists of an acquisition and reconstruction technique allowing simultaneous excitation of multiple volumes to accelerate imaging acquisition times, or increasing coverage or number of diffusion directions without increasing scan time. Fundamental Scientific The MultiBand SENSE feature enables simultaneous Technology: excitation and acquisition of multiple volumes or slices for the purpose of speeding up acquisition times or increasing coverage or resolution at constant scan time. The simultaneous excitation is done using a multi-band radiofrequency pulse. The unfolding of the simultaneously acquired volumes is done using the SENSE algorithm. The unfolding process (solving the linear equation of the SENSE algorithm) is improved by introducing a linear phase over k-space in the volume direction resulting in a spatial shift of the aliased pixels. The phase shift is applied by additional blip-gradients in the slice direction or switching between different RF pulses, and compensated for in reconstruction by a translation of the coil sensitivity data before the SENSE unfolding. The feature consists of: ● Modulated RF pulses exciting 2 or more spatial slice locations Blip-gradients to introduce a phase shift on slices for . improved unfolding . Shifting coil sensitivities in reconstruction to correct for linear phase shift. Automatic use of Bo inhomogeneity information to . correct geometric distortions in the SENSE calculation
