Objective(s): A novel IQ-SPECTTM method has become widely used in clinical studies. The present study compares the quality of myocardial perfusion images (MPI) acquired using the IQ-SPECTTM (IQ-mode),conventional (180° apart: C-mode) and L-mode (90° apart: L-mode) systems. We assessed spatial resolution, image reproducibility and quantifiability using various physical phantoms. Materials and Me...

objective(s): use of a positron emission tomography (pet)/single-photonemission computed tomography (spect) system facilitates the simultaneousacquisition of images with fluorine-18 fluorodeoxyglucose (18f-fdg) andtechnetium (99mtc)-tetrofosmin. however, 18f has a short half-life, and 511kev compton-scattered photons are detected in the 99mtc energy window.therefore, in this study, we aimed to ...

This paper presents a dual-mode modeling approach based on innovation design and engineering design, which is applied to the design of belt conveyor. Dual mode modeling method fusions innovation design pattern and engineering design mode, and realizes a combination of liberalization design and precision design, while the traditional parametric modeling is restricted by single thought, which exi...

Sub-threshold is a new paradigm in the digital VLSI design today. In Sub-threshold region, transistors are operated in sub-threshold voltage. This paper examine the Carry Look Ahead (CLA) Adder with dual mode logic (DML)principle, in which gates are operated in sub-threshold regime and comparison of results with Conventional basic Carry look ahead adder . The number of gates in CLA is 5 includi...

We address a new blind equalizer incorporating both the good initial convergence characteristic of the dual-mode modified constant modulus algorithm (MCMA) and the low residual error characteristic after convergence of the decision-directed (DD) algorithm. In the proposed scheme, a convergence detector is employed to help switching from the dual-mode MCMA to the DD algorithm. We have observed t...
