Volume Reconstruction from Sparse 3D Ultrasonography [PDF]

open access: yes, 2003
3D freehand ultrasound has extensive application for organ volume measurement and has been shown to have better reproducibility than estimates of volume made from 2D measurement followed by interpolation to 3D. One key advantage of free-hand ultrasound is that of image compounding, but this advantage is lost in many automated reconstruction systems.

Group sparse reconstruction using intensity‐based clustering [PDF]

open access: yesMagnetic Resonance in Medicine, 2012
Compressed sensing has been of great interest to speed up the acquisition of MR images. The k‐t group sparse (k‐t GS) method has recently been introduced for dynamic MR images to exploit not just the sparsity, as in compressed sensing, but also the spatial group structure in the sparse representation.

Sparse‐Coding‐Based Computed Tomography Image Reconstruction [PDF]

open access: yesThe Scientific World Journal, 2013
Computed tomography (CT) is a popular type of medical imaging that generates images of the internal structure of an object based on projection scans of the object from several angles. There are numerous methods to reconstruct the original shape of the target object from scans, but they are still dependent on the number of angles and iterations.

Sparse image reconstruction on the sphere: implications of a new sampling theorem

open access: yes, 2013
We study the impact of sampling theorems on the fidelity of sparse image reconstruction on the sphere. We discuss how a reduction in the number of samples required to represent all information content of a band-limited signal acts to improve the fidelity

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting
