نویسندگان
چکیده
accuracy of GROWL recon. (a)-(c): Reference image (a, 256x256), reconstruction using 8 radial lines with regridding (b) and GROWL (c). (d)-(e): Maximal correlation (d) and average rotational errors (e) with different no. of views. Fig. 1 GROWL reconstruction scheme. (a) The original undersampled dataset with a small Nyquist circle. (b) After each radial view is widened into a band using a GRAPPA operator, the Nyquist circle is enlarged.

Retrospective reconstruction of high temporal resolution cine images from real-time MRI using iterative motion correction.
Cardiac function has traditionally been evaluated using breath-hold cine acquisitions. However, there is a great need for free breathing techniques in patients who have difficulty in holding their breath. Real-time cardiac MRI is a valuable alternative to the traditional breath-hold imaging approach, but the real-time images are often inferior in spatial and temporal resolution. This article pr...
متن کاملMotion correction for functional MRI with three‐dimensional hybrid radial‐Cartesian EPI
PURPOSE Subject motion is a major source of image degradation for functional MRI (fMRI), especially when using multishot sequences like three-dimensional (3D EPI). We present a hybrid radial-Cartesian 3D EPI trajectory enabling motion correction in k-space for functional MRI. METHODS The EPI "blades" of the 3D hybrid radial-Cartesian EPI sequence, called TURBINE, are rotated about the phase-e...
متن کاملAdvanced Motion Correction Methods in PET
With the arrival of increasingly higher resolution PET systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. In this work, we have reviewed advanced correction methods for the three cases of (i) unwanted patient motion, as well as motions due to (ii) cardiac and (iii) respiratory cycles. For the first type of ...
متن کاملAcceleration and motion-correction techniques for high-resolution intravascular MRI.
PURPOSE High-resolution intravascular (IV) MRI is susceptible to degradation from physiological motion and requires high frame-rates for true endoscopy. Traditional cardiac-gating techniques compromise efficiency by reducing the effective scan rate. Here we test whether compressed sensing (CS) reconstruction and ungated motion-compensation using projection shifting, could provide faster motion-...
متن کاملGRAPPA Operator for Wider RadiaL Band (GROWL)
Fig. 2 Comparison of in vivo gradient echo images using conventional regridding (top), GROWL reconstruction without (middle) and with (bottom) regularization. Reduction factor R is shown at the top-left corner of each panel, while numbers at the bottom-right corners are normalized error percentage from the gold-standard (R=1, 256 view) image. For GROWL, the number of parallel k-space lines with...
