Summary: The evidence supporting the use of intracoronary imaging (ICI) in guiding percutaneous coronary intervention (PCI) is increasing. ICI provides detailed information about coronary disease and can influence stent selection and lesion preparation. However, the widespread adoption of ICI is hindered by cost, procedure time, regulatory issues, and a lack of education and interpretation challenges.

Summary: Imaging-guided coronary bifurcation intervention improves clinical outcomes by properly selecting device sizes and optimizing the procedure. Three-dimensional optical coherence tomography (3D OCT) provides clear visualization of stent configuration and guidewire position, aiding in optimal guidewire crossing. In two-stent deployment, 3D OCT facilitates optimal guidewire crossing, reducing metal carina clustering and overlap.

Summary: This work demonstrates 3D depth-invariant cellular-resolution imaging of the living human retina over a 3 x 3 mm field of view using the first intrinsically phase-stable multi-MHz retinal swept-source OCT and novel computational methods. It provides wide-field 3D cellular-resolution imaging in the human retina, which can bring a great impact in clinical ophthalmology.

Summary: This study visualized and investigated the three-dimensional images of macular neovascularization (MNV) using optical coherence tomography angiography (OCTA) and examined the changes in vascular volume according to the treatment response. The results showed that the volume of MNV decreased significantly in the fluid-free group after treatment, while there was no significant change in the persistent fluid group.

Summary: A study was conducted on measuring special shaped contact lenses using a time-domain optical coherence tomography device. An algorithm combined with sphere fitting was proposed for shape, thickness, and curvature radius estimation. The accuracy was verified using simulated data, and evaluation of a toric-shaped mold was done by comparing coordinates and intensity of interference signals.

Summary: A multiscale extension for the well-known block matching and 4D filtering (BM4D) method is proposed by analyzing and extending the wavelet subbands denoising method in such a way that the proposed method avoids directly denoising detail subbands, which considerably simplifies the computations and makes the multiscale processing feasible in 3D.

Summary: The study utilized optical coherence tomography (OCT) to evaluate the quality of bovine preimplantation embryos and found that OCT imaging can be used to select high-quality embryos for transfer. Results suggest that TE volume may be a key parameter for the evaluation of bovine embryos, indicating the potential of OCT in improving embryo selection for successful pregnancies.

Summary: The proposed 3D registration and averaging method significantly improved vessel connectivity and signal to noise ratio in the imaging performance, with an increase in all assessed metrics such as SNR, PSNR, and NCC with the increase in repeated volume averaging. An improvement of SNR from 10 to 40 dB was achieved after 10 repeated volumetric averaging, demonstrating the effectiveness of the method in reducing speckle noises and motion artifacts.

Summary: A 3D color camera based on OCT is proposed, which records moving objects images by acquiring precise surface topography maps and fusing color images. Cross-correlation and tracking scanning are used to determine the objects' position, and a topography algorithm and models are applied to reconstruct images. Experiment on a coin demonstrates the potential for further development of the 3D color camera to record 3D color images or videos of moving objects.

Summary: This study explores the use of three-dimensional spectral-domain optical coherence tomography (SD-OCT) to identify different follicular stages in mice ovaries and measure their size and age-related density distribution differences. The results show that SD-OCT is a promising noninvasive method for evaluating ovarian follicles, which is helpful for ovarian tissue cryopreservation.

Summary: Motion correction is crucial in ophthalmic OCT imaging to improve data quality and aid in easier visualization and analysis. This study introduces a novel method for correcting motion artifacts in retinal OCT volumes, using a combination of normalized cross-correlation and polynomial fitting algorithms. Results from patients with central serous chorioretinopathy show that this method effectively corrects motion artifacts and could have potential applications in assessing ophthalmic diseases.

Summary: Despite advances in diagnosis and treatment, identifying unstable lesions in atherosclerotic coronary artery disease remains challenging. Researchers have developed an algorithmic approach to automatically create 3D finite element models from OCT images, accurately simulating the morphology and mechanical properties of lesions. This automated process allows for analysis of large clinical cohorts and enables in-silico methods for personalized diagnoses and treatment planning for coronary artery disease.
