Super-resolution (SR) image reconstruction is the process of combining several low resolution images into a single higher resolution image. There is a driving need for digital images of higher resolutions and quality. However, there is a limit to the spatial resolution that can be recorded by any digital device. Growing interest in super-resolution (SR) restoration of video sequences and the cl...

This article describes a quantitative evaluation of visualizing small vessels using several image reconstruction methods in computed tomography. Simulated vessels with diameters of 1-6 mm made by 3D printer was scanned using 320-row detector computed tomography (CT). Hybrid iterative reconstruction (hybrid IR) and model-based iterative reconstruction (MBIR) were performed for the image reconstr...

Positron emission tomography (PET) image reconstruction is challenging for low count frame. The reconstruction is important method to retrieve information that has been lost in the images. To improve image quality, prior information are used. Based on kernel method, PET image intensity in each pixel is obtained from prior information and the coefficients can be estimated by the maximum likeliho...

OBJECTIVE To prospectively evaluate the psychosocial outcomes and body image of patients 2 years postmastectomy reconstruction using a multicenter, multisurgeon approach. BACKGROUND Although breast reconstruction has been shown to confer significant psychosocial benefits in breast cancer patients at year 1 postreconstruction, we considered the possibility that psychosocial outcomes may remain...

Super-resolution (SR) image reconstruction is a technique to generate a high resolution (HR) image from several low resolution (LR) images of the same scene, which can improve the visual effect of images or serve as a pre-processing technique. Among various SR image reconstruction schemes, sparse representation based SR image reconstruction schemes have become the current research focus because...

C-arm cone-beam CT offers great potential in image-guided interventions, but conventional analytic reconstruction methods are associated with limited image quality, particularly for soft-tissue imaging. While model-based iterative reconstruction (IR) methods improve image quality and/or reduce radiation dose, long reconstruction time limits utility in clinical workflow. Additionally, in contras...
