This study proposes a new method to reconstruct three dimensional (3D) tongue surface motion during speech using only a few sections of the tongue measured with ultrasound imaging. Reconstruction of static 3D tongue surfaces has been reported. This is the first report for reconstruction of 3D tongue surface motion using ultrasound imaging. To temporally align data from multiple scan locations, ...

OBJECTIVE To evaluate the feasibility of five-dimensional Long Bone (5D LB), a new technique that automatically archives, reconstructs images, and measures lengths of fetal long bones, to assess whether the direction of volume sweep influences fetal long bone measurements in three-dimensional (3D) ultrasound and 5D LB, and to compare measurements of fetal long bone lengths obtained with 5D LB a...

3D registration of ultrasound images is an important and fast-growing research area with various medical applications, such as image-guided radiotherapy and surgery. However, this registration process is extremely challenging due to the deformation of soft tissue and the existence of speckles in these images. This paper presents a novel intra-modality elastic registration technique for 3D ultra...

The developmental goal of 3D ultrasound imaging (3DUS) is to engineer a modality to perform 3D morphological ultrasound analysis of human muscles. 3DUS images are constructed from calibrated freehand 2D B-mode ultrasound images, which are positioned into a voxel array. Ultrasound (US) imaging allows quantification of muscle size, fascicle length, and angle of pennation. These morphological vari...

Very high frame rate ultrasound imaging has recently allowed for the extension of the applications of echography to new fields of study such as the functional imaging of the brain, cardiac electrophysiology, and the quantitative imaging of the intrinsic mechanical properties of tumors, to name a few, non-invasively and in real time. In this study, we present the first implementation of Ultrafas...

Systematic transrectal ultrasound (TRUS)-guided biopsy is the standard method for a definitive diagnosis of prostate cancer. However, this biopsy approach uses two-dimensional (2D) ultrasound images to guide biopsy and can miss up to 30% of prostate cancers. We are developing a molecular image-directed, three-dimensional (3D) ultrasound image-guided biopsy system for improved detection of prost...

BACKGROUND 3D ultrasound volume reconstruction from B-model ultrasound slices can provide more clearly and intuitive structure of tissue and lesion for the clinician. METHODS This paper proposes a novel Global Path Matching method for the 3D reconstruction of freehand ultrasound images. The proposed method composes of two main steps: bin-filling scheme and hole-filling strategy. For the bin-f...

Objective: to investigate the accuracy of 2D and 3D ultrasound in measurement of Cesarean section (CS) scar thickness. Study design: A prospective observational study conducted on 75 pregnant women with previous 1 or 2 CS candidates for elective CS. Evaluation of LUS using 2D and 3D transabdominal and transvaginal ultrasound is then correlated to scar integrity assessed intraoperatively. Result...

Both three-dimensional (3D) and four-dimensional (4D) ultrasound have improved our knowledge regarding the develop ment of the embryo and fetus and of a great number of fetal anomalies. The great achievement in the field of 3D/4D ultrasound is HDlive technology. This technology is a novel ultrasound technique that improves the 3D/4D images. Furthermore, recent advanced 3D technology has produce...

The most attractive feature of 2D B-mode ultrasound for intra-operative use is that it is both a real time and a highly interactive modality. Most 3D freehand reconstruction methods, however, are not fully interactive because they do not allow the display of any part of the 3D ultrasound image until all data collection and reconstruction is finished. We describe a technique whereby the 3D recon...
