A novel method of motion compensation for use with radiation force elastography is discussed. Results suggest the effectiveness of the proposed method for in vivo abdominal imaging.

The feasibility of acoustic radiation force impulse (ARFI) imaging with an intracardiac probe and its possible application for monitoring cardiac ablations are investigated. It is found that the intracardiac probe can define the boundaries of a stiffer spherical lesion clearly and hence can guide and monitor radiofrequency ablations within the heart.

Acoustic radiation force impulse (AFRI) imaging techniques were used to monitor radiofrequency (RF) ablation of ovine cardiac tissue in vivo. AFRI imaging, which requires no additional equipment, might be convenient modality for monitoring lesion formation in vivo.

The article focuses on the conceptual framework underlying the school-to-prison pipeline via an analysis of the rights attendant to the above-described models with the U.S. Supreme Court cases Goss v. Lopez and Ingraham v. Wright school discipline towards criminal punishment.

The article reports on the jurisdiction of the Nebraska Supreme Court in the court case 'J.P. ex. rel. A.P. v. Millard Public Schools' in which the court confronted the limits of a school's authority to search students. Topics discussed include protection afforded by the students under the U.S. Constitution, relationship between school officials' and the applicability of the Constitution to students, and the court's ruling in the context to the development of Fourth Amendment jurisprudence.
