Magnetic resonance thermal imaging combined with SMASH navigators in the presence of motion
This study develops and tests an MR thermometry method combined with SMASH navigators in phantom experiments mimicking human liver motion with the purpose of detecting and correcting motion artifacts in thermal MR images. Experimental data were acquired on a 3T MRI scanner. Motion artifacts of mobile phantoms mimicking human liver motion were detected and corrected using the SMASH navigators an...
متن کاملAnd the Big Smash
Recent observations suggest that the cosmological equation-of-state parameter w is close to−1. To say this is to imply thatw could be slightly less than−1, which leads to R.Caldwell’s “Phantom cosmologies”. These often have the property that they end in a “Big Smash”, a final singularity in which the Universe is destroyed in a finite proper time by excessive expansion. We show that, classically...
متن کاملVD-AUTO-SMASH imaging.
Recently a self-calibrating SMASH technique, AUTO-SMASH, was described. This technique is based on PPA with RF coil arrays using auto-calibration signals. In AUTO-SMASH, important coil sensitivity information required for successful SMASH reconstruction is obtained during the actual scan using the correlation between undersampled SMASH signal data and additionally sampled calibration signals wi...
متن کاملEquivariant Structure on Smash Powers
Since the early 1990's there have been several useful symmetric monoidal model structures on the underlying category of a point set category of spectra. Topological Hochschild homology (THH) is constructed from smash powers of ring-spectra, that is, monoids in the category of spectra. Already in the 1980's such a construction was made. Building on ideas of Goodwillie and Waldhausen, Bökstedt in...
متن کاملSMASH - A Cryptographic Hash Function
1 This paper presents a new hash function design, which is different from the popular designs of the MD4-family. Seen in the light of recent attacks on MD4, MD5, SHA-0, SHA-1, and on RIPEMD, there is a need to consider other hash function design strategies. The paper presents also a concrete hash function design named SMASH. One version has a hash code of 256 bits and appears to be at least as ...
