The precise alignment of 3D echocardiographic images taken from different views has been shown to enhance image quality and increase the field of view. This study proposes a novel sequential Monte Carlo (SMC) algorithm for the 3D-3D rigid registratio

The quality of ultrasound (US) imaging has been constrained by its limited contrast and resolution, inherent speckle noise, and the presence of other artifacts. Existing traditional and deep learning-based US denoising approaches have many limitation

Deformable image registration plays a crucial role in estimating cardiac deformation from a sequence of images. However, existing registration methods primarily process images as pairs instead of processing all images in a sequence together. This stu

Left ventricular segmentation is a difficult and time-consuming task performed by clinicians, requiring the use of manual contours. We propose a novel three-dimensional diffeomorphic registration algorithm for endocardial segmentation of the left ven

AimsStudies of infant hip development to date have been limited by considering only the changes in appearance of a single ultrasound slice (Graf’s standard plane). We used 3D ultrasound (3DUS) to establish maturation curves of normal infant hip dev

The use of three-dimensional (3D) technologies in medical practice is increasing; however, its use is largely untested. One 3D technology, stereoscopic volume-rendered 3D display, can improve depth perception. Pulmonary vein stenosis (PVS) is a rare

Skin moles are one of the most critical conditions for early diagnosis of severe conditions such as melanoma. Early identification of moles has become crucial nowadays, primarily due to malignant melanoma, a dangerous type of skin cancer. Most of the
