Joint Co-segmentation and Registration of 3D Ultrasound Images
Contrast-enhanced ultrasound (CEUS) allows a visualization of the vascularization and complements the anatomical information provided by conventional ultrasound (US). However, these images are inherently subject to noise and shadows, which hinders standard segmentation algorithms. In this paper, we propose to use simultaneously the different information coming from 3D US and CEUS images to addr...
متن کاملClinical application of three-dimensional ultrasound in fetal brain assessment.
AIM To clarify the usefulness of three-dimensional (3D) ultrasound in the assessment of the fetal head and brain, according to 3D ultrasound surface reconstruction, multiplanar image analysis, three-dimensional angiography, and volume calculation. METHODS We examined 326 normal fetuses between 10 and 40 weeks of gestation using 3D ultrasound (Voluson, 530D, Medison, Seoul, Korea), mainly with...
متن کاملبخشبندی معنادار مدل سهبعدی اجسام بر اساس استخراج برجستگیها و هسته جسم
3D model segmentation has an important role in 3D model processing programs such as retrieval, compression and watermarking. In this paper, a new 3D model segmentation algorithm is proposed. Cognitive science research introduces 3D object decomposition as a way of object analysis and detection with human. There are two general types of segments which are obtained from decomposition based on thi...
متن کاملAutomatic extraction of generic focal features on 3D shapes via random forest regression analysis of geodesics-in-heat
Flexible definition and automatic extraction of generic features on 3D shapes is important for feature-centric geometric analysis, however, existing techniques fall short in measuring and locating semantic features from users’ psychological standpoints. This paper makes an initial attempt to propose an learning based generic modeling approach for usercentral definition and automatic extraction ...
متن کاملDifference of Gaussians revolved along elliptical paths for ultrasound fetal head segmentation
We present a fully automatic method to segment the skull from 2-D ultrasound images of the fetal head and to compute the standard biometric measurements derived from the segmented images. The method is based on the minimization of a novel cost function. The cost function is formulated assuming that the fetal skull has an approximately elliptical shape in the image and that pixel values within t...
