Comparison of registration strategies for USCT–MRI image fusion: preliminary results

Comparing Ultrasound Computer Tomography (USCT) to the well-known Magnetic Resonance Imaging (MRI) is an essential step in evaluating the clinical value of USCT. Yet the different conditions of the breast either embedded in water (USCT) or in air (MRI) prevent direct comparison. In this work we compare two strategies for image registration based on biomechanical modeling to automatically establish spatial correspondence: a) by applying buoyancy to the MRI, or b) by removing buoyancy from the USCT. The registration was applied to 9 datasets from 8 patients. Both registration strategies revealed similar registration accuracies (MRI to USCT: mean = 5.6 mm, median = 5.6 mm, USCT to MRI: mean = 6.6 mm, median = 5.7 mm). Image registration of USCT and MRI allows to delineate corresponding tissue structures in both modalities in the same or nearby slices. Our preliminary results indicate that both simulation strategies seem to perform similarly. Yet the newly developed deformation of the USCT volume is less computationally demanding: As the breast is subjected to buoyancy it can thereby serve as the unloaded state while for the contrary strategy we have to solve an inverse problem

113th Congress

Report that describes and analyzes student loan interest rate proposals that have been made in the 113th Congress to establish new policies for setting the interest rates that borrowers will pay on loans made through the Direct Loan program

Campus-Based Student Financial Aid Programs Under the Higher Education Act

This report discusses the issues likely to be considered during reauthorization are whether the campus-based programs provide types of aid to students that are not or cannot be provided via other postsecondary aid programs, and whether the current formulas for allocating funds to institutions for the operation of these programs are optimal. Provisions specific to each program, such as requirements for community service under FWS and terms and conditions of Perkins Loans also may be considered

The Campus-Based Financial Aid Programs: A Review and Analysis of the Allocation of Funds to Institutions and the Distribution of Aid to Students

This report describes and analyzes (a) the process through which federal funds are allocated to institutions under the campus-based programs, (b) the potential for allocating all campus-based funding according to the existing need-based formulas, and (c) the current distribution of aid to students. It will be updated to track legislative proposals addressing the campus-based allocation procedures

Supplemental Educational Services for Children from Low-Income Families Under ESEA Title I-A

This report discusses supplemental educational services in the general sense, which include educational activities provided outside of normal school hours that are designed to augment or enhance the educational services provided during regular periods of instruction

Interest Rates on Subsidized Stafford Loans to Undergraduate Students

Beginning July 1, 2012, Subsidized Stafford Loans will be available exclusively to undergraduate students. The federal government "subsidizes" these loans by relieving the borrower of the requirement to pay the interest that accrues while the borrower is in school and during other authorized periods. In the 112th Congress, proposals have been made to reduce the interest rate applicable to Subsidized Stafford Loans that will be made to undergraduate students during AY2012-2013 from 6.8% to 3.4%. Proposals include the Interest Rate Reduction Act and the Stop the Student Loan Interest Rate Hike Act of 2012. It is estimated that a reduction in the interest rate would benefit approximately 7.4 million students who are likely to borrow Subsidized Stafford Loans during the upcoming award year
