Summary: Matrix imaging is revolutionizing wave physics by optimizing compensation for aberrations and multiple scattering in heterogeneous media. This paper extends ultrasound matrix imaging to a 3D geometry and proposes a non-invasive approach to make the skull transparent for improved brain imaging.

Summary: The characterisation of fast phenomena at the microscopic scale is necessary for understanding various key technologies and processes, such as the responses of materials to loads and shocks, material processing, additive manufacturing, microfluidics, and fuel mixing in combustion. This paper demonstrates a method to record three-dimensional X-ray movies of irreversible processes with high resolutions and frame rates by combining stereo phase-contrast images. The method can be further extended to include more than two simultaneous views, and when combined with X-ray free-electron lasers (XFELs), it can achieve movies capable of resolving 3D trajectories at high velocities.

Summary: High-resolution 3D imaging is used to improve our understanding of the brain microstructure, complementing classical 2D histological assessment techniques. Contrast-enhanced computed tomography (CECT) using staining agents allows for high-resolution imaging of soft tissues. This research introduced four new non-toxic and non-destructive contrast-enhancing staining agents for ex vivo brain CECT imaging.

Summary: A new method is developed for 3D reconstruction of multimaterial objects using PB-CT with phase retrieval via CTF formalism. The method performs phase retrieval to the CT-reconstructed volume in 3D, leading to fast and stable phase retrieval and increased computational efficiency. The extended validity of CTF to greater propagation distances provides additional advantages over approaches based on the transport-of-intensity equation.

Summary: This study investigated a three-dimensional noncontrast bimodal photoacoustic/ultrasound imaging system to quantitatively and reliably assess the microcirculation of the human foot noninvasively. The imaging system was able to visualize the morphologic and physiologic features of the foot, including the peripheral microvasculature, in healthy volunteers.

Summary: MRI-based 3D printing is a potentially promising technique for surgical planning of cloacal malformation correction in patients with a long common channel, as it provides detailed information about the surrounding soft tissue structures without exposure to radiation or contrasting agents.

Summary: This study evaluated the use of three-dimensional H-scan ultrasound imaging for monitoring early breast cancer response to neoadjuvant therapy. The results showed that the H-scan imaging technique is sensitive to changes in tumors after apoptosis-inducing drug therapy and correlates with cancer cell nuclear size. It has the potential to visualize the entire tumor and detect breast cancer response at an early stage of therapy.

Summary: This paper proposes a method to reconstruct compressed hyperspectral (HS) data using convolutional neural networks (CNNs). By dividing the imaging process into multiple steps and building a subnetwork for each step, this method can reconstruct compressed HS data quickly and accurately, while having superior resistance to noise.

Summary: In this paper, a three-dimensional reconstruction procedure based on coherent modulation imaging is presented, which allows the recovery of phase and intensity of the sample from diffraction patterns. Pre-processing methods to remove illumination probe, address inherent ambiguities in phase reconstruction results, and handle intensity fluctuation are provided. The projections extracted by this method can be used with standard tomographic reconstruction frameworks to accurately recover quantitative three-dimensional phase and intensity images. Numerical simulations and optical experiments validate the effectiveness of the proposed method.

Summary: The mechanical properties of skeletal muscle tissue at an intermediate scale can provide insights into diseases such as muscular dystrophies. In this study, the micro-scale elasticity of murine skeletal muscle was characterized using quantitative micro-elastography (QME). By encapsulating the muscles in transparent hydrogels with flat surfaces, high-quality QME images were obtained. The results showed a significant decrease in elasticity in dysferlin-deficient quadriceps compared to wild-type quadriceps, indicating the impact of dysferlinopathy on muscle function.

Summary: This study designs, fabricates, and validates a 3D acquisition system for accurate volumetric prostate imaging using the ExactVu microUS device. Geometric validation shows accuracy of 1 mm or less in all three directions, and the images of an anthropomorphic phantom qualitatively match those acquired using MRI and show good agreement quantitatively. Therefore, this system enables future applications of the ExactVu microUS system in prostate specimen and in vivo imaging.
