Three-dimensional (3-D) imaging of chondrocytes in articular cartilage: growth-associated changes in cell organization. [PDF]
Biomaterials, 2007 Three-dimensional (3-D) imaging and analysis techniques can be used to assess the organization of cells in biological tissues, providing key insights into the role of cell arrangement in growth, homeostasis, and degeneration. The objective of the present study was to use such methods to assess the growth-related changes in cell organization of ...

High-resolution High-dimensional Imaging of Urban Building Based on GaoFen-3 SAR Data
Leida xuebao, 2022 Conventional Synthetic Aperture Radar (SAR) can only obtain two-dimensional (2-D) azimuth-range images without accurately reflecting the three-Dimensional (3-D) scattering structure information of the targets. However, SAR Tomography (TomoSAR) is a multi-

Three-Dimensional Microwave Head Imaging with GPU-Based FDTD and the DBIM Method
Sensors, 2022 We present a preliminary study of microwave head imaging using a three-dimensional (3-D) implementation of the distorted Born iterative method (DBIM). Our aim is to examine the benefits of using the more computationally intensive 3-D implementation in ...

Tomographic SAR Imaging Method Based on Sparse and Low-rank Structures
Leida xuebao, 2022 This paper proposes a three-dimensional tomographic SAR imaging method based on a combined sparse and low-rank structures. The traditional Compressed Sensing (CS) based tomographic SAR imaging methods only utilize the sparse representation and ...
