چکیده

While Aspect-oriented programming (AOP) [Kic+97] enables modularization of crosscutting concerns, Reflection [Smi82] is commonly recognized as a valuable instrument for separation of concerns [Coi99]. In this short paper, we explore the relationships between reflection and AOP. This study is carried out in the context of a project about dynamic adaptability of distributed systems [RNTL00]. We propose a combination of the two approaches to obtain the best of both worlds. The proposed prototype shows that AspectJ [Kic+01] and run-time reflection in Java can be combined together to support run-time weaving.

New approach for attenuation correction in SPECT images, using linear optimization

Background: Photon attenuation as an inevitable physical phenomenon influences on the diagnostic information of SPECT images and results to errors in accuracy of quantitative measurements. This can be corrected via different physical or mathematical approaches. As the correction equation in mathematical approaches is nonlinear, in this study a new method of linearization called ‘Piece ...

Relationship between the optimum cut off frequency for Butterworth filter and lung-heart ratio in 99mTc myocardial SPECT

Background: We investigated whether the lungheart ratio parameter (LHR) can be used to identify the optimum cut off frequency for Butterworth filter in 99mTc myocardial SPECT imaging. Materials and Methods: This study involved a cardiac phantom system consisting of cardiac insert in which 1.10 cm cold defect was inserted into its myocardium wall and filled with 4.0 μCi/ml (0.148 MBq/ml...

Assessment of the impact of applying attenuation correction on the accuracy of activity recovery in Tc99m-ECD brain SPECT of healthy subject using Statistical Parametric Mapping (SPM)

Introduction: Photon attenuation in tissues is the primary physical degrading factor limiting both visual qualitative interpretation and quantitative analysis capabilities of reconstructed Single Photon Emission Computed Tomography (SPECT) images. The aim of present study was to investigate the effect of attenuation correction on the detection of activation foci following statistical analysis w...
