With the development of ultra-high-resolution display devices, the visual perception of fine texture details is becoming increasingly important. Traditional image upsampling methods suffer from either loss of highfrequency texture details or very high time cost. In this paper, we propose an iterative projection reconstruction (IPR) method for fast and efficient image upsampling. The proposed me...

Existing algorithms for exact helical cone beam (HCB) tomographic reconstruction are computationally infeasible for clinical applications. Their computational cost is dominated by 3-D backprojection, which is generally an operation. We present a fast hierarchical 3-D backprojection algorithm, generalizing fast 2-D parallel beam and fan beam algorithms, which reduces the overall complexity of th...

Aim: Permanent expanders allow for breast reconstruction as a single stage. These prostheses are more expensive than conventional tissue expanders, but this excess cost is markedly offset as only one operation is required. However, if the revision rate is sufficiently high, then this effect is negated. We aim to compare costs of one-stage vs. two-stage reconstruction at a single center, taking ...

A fast Inverse Polynomial Reconstruction Method (IPRM) is proposed to efficiently eliminate the Gibbs phenomenon in Fourier reconstruction of discontinuous functions. The framework of the fast IPRM is modified by reconstructing the function in discretized elements, then the Conformal Fourier Transform (CFT) and the Chirp Z-Transform (CZT) algorithms are applied to accelerate the evaluation of r...

In sensor networks, energy efficient data manipulation / transmission is very important for data gathering, due to significant power constraints on the sensors. As a potential solution, Compressed Sensing (CS) has been proposed, because it requires capturing a smaller number of samples for successful reconstruction of sparse data. Traditional CS does not take explicitly into consideration the c...

PURPOSE To examine the role of palivizumab, a monoclonal antibody vaccine designed to prevent respiratory syncytial virus (RSV) infection, in the surgical setting, and to explore the feasibility, in terms of medical benefit and cost, of its use in pediatric airway reconstruction patients. MATERIALS AND METHODS Literature review of MEDLINE database using the following indexing terms ("respirat...

BACKGROUND Despite the significance of anterior cruciate ligament (ACL) injuries, these conditions have been under-researched from a population-level perspective. It is important to determine the economic effect of these injuries in order to document the public health burden in the United States. PURPOSE To describe the cost of outpatient arthroscopic ACL reconstruction and health care utiliz...

BACKGROUND Intraoperative angiography is a useful tool for predicting both tissue perfusion during postmastectomy breast reconstruction and mastectomy flap and free flap survival. OBJECTIVES The authors determine whether the routine use of laser-assisted indocyanine green (ICG) fluorescence angiography (SPY Imaging; LifeCell Corp, Branchburg, New Jersey) in breast reconstruction decreases the...

Using a far-field model, bistatic synthetic aperture radar (SAR) acquires Fourier data on a rather unusual, non-Cartesian grid in the Fourier domain. Previous image formation algorithms were mainly based on direct Fourier reconstruction to take advantage of the FFT, but the irregular coverage of the available Fourier domain data and the 2-D interpolation in the Fourier domain may adversely affe...

PURPOSE The purpose of this study is to compare complication rate, primary patency, and cost of stent deployment with direct surgical reconstruction for the treatment of severe aortoiliac occlusive disease. METHODS From March 1, 1992, to May 31, 1996, 119 patients receiving treatment for aortoiliac occlusive disease were analyzed after exclusions. Sixty-five patients had stent deployment and ...
