Ultrasound (US) represents the first-line imaging modality for initial diagnostic assessment of liver pathology and in many cases the optimal modality for serial follow-up. US not only offers anatomic information with excellent spatial resolution in the near and mid field with grayscale imaging, ...
images, the patients were divided into four groups: group A fatty liver images, group B liver fibrosis or early liver cirrhosis images, group C advanced liver cirrhosis (with or without portal hypertension), and group D normal liver images.Two doctors were arranged to do the image ...
Hepatus is a professional non-invasive diagnostic system for liver diseases, providing quantitative result to indicate the stage of liver fibrosis. It is accurate, efficient, reliable, and convenient for disease follow-up, opening a new era for non-invas
Electromagnetic (EM) tracking was used for organ tracking and movement of the transducer. After laparotomy, a sensor was attached to the liver surface while the EM-tracked US transducer enabled image acquisition and landmark digitization. Landmarks surrounding the lesion were selected during patient-...
3.1 当超声被看作是图像(Image) 当我们将超声影像视作图像的时候,一般认为其是一个八连通图,每次的超声扫描线将形成该图的一个行列: 图片来自:TUM – Computer Aided Medical Procedure I 这种做法通常是希望将超声影像用于深度学习模型的训练过程,或者是给医师进行可视化操作。
The purpose of this study is to develop a 2D-3D US image registration method for tracking the movement of liver vessels. First, the 3D coordinates of US volume and US image were calculated by measuring the position and the posture of US probe using a 3D position sensor. Next, regarding th...
Diagnostic accuracy of whole-body MRI/DWI image fusion for detection of malignant tumours: a comparison with PET/CT Objective To prospectively evaluate the diagnostic accuracy of whole-body T2-weighted (wbT2), whole-body diffusion-weighted imaging (wbDWI) and wbT2... Michael,A.,Fischer,... ...
However the Color Doppler image of case 1 clinches the diagnosis of ectopia cordis. This was a early 2nd trimester fetus. Case-1 ultrasound images are courtesy of Dr. Dilraj Gandhi, India. This fetus also shows increased Nuchal thickness.Case-2 shows ectopia cordis with heart partially ou...
this technique [66]. Another limitation of CEUS is that, like B-mode ultrasound, it is heavily dependent on the plane of the image and largely affected by acoustic shadowing. It is important that future studies aim to standardize CEUS variables, such as dose of contrast and imaging parameters...
