The manual outlining of hepatic metastasis in (US) ultrasound acquisitions from patients suffering from pancreatic cancer is common practice. However, such pure manual measurements are often very time consuming, and the results repeatedly differ between the raters. In this contribution, we study the in-depth assessment of an interactive graph-based approach for the segmentation for pancreatic metastasis...
In clinical diagnosis of liver cancer or treatment using US image guided navigation often required correlation of suspicious region in US with the clinical findings on CT or MR images. We proposed a faster automated registration technique consists of two-steps registration framework which contains vessel structure-based coarse registration and gradient feature-based fine registration. Results were...
Clinical Decision Support (CDS) aids in early diagnosis of liver cancer, a potentially fatal disease prevalent in both developed and developing countries. Our research aims to develop a robust and intelligent clinical decision support framework for disease management of cancer based on legacy Ultrasound (US) image data collected during various stages of liver cancer. The proposed intelligent CDS framework...
In this paper, we present a novel approach to rigidly register intraoperative electromagnetically tracked ultrasound (US) with pre-operative contrast-enhanced magnetic resonance (MR) images. The clinical rationale for this work is to allow accurate needle placement during thermal ablations of liver metastases using multimodal imaging. We adopt a model-based approach that rigidly matches segmented...
The authors developed and tested a quantitative ultrasound technique (CAUS) for the staging of steatosis using Ultrasound Tissue Characteristics Parameters (UTCPs) from B-mode images [1]. CAUS method pre-processing steps in short: transformation of the gray level to logarithmic echo level by linearization of the post-pocessing Look Up Table (LUT); Back-Scan conversion of sector image format, i.e.,...
Hemangioma is one of the most common benign congenital complications of the human body which can arise in interior organs and external limbs. The main aim of this work is to present a new method for automatic detection of liver hemangioma and its boundaries in ultrasound images, using image processing techniques. Overall there are two phases, the preprocessing procedure and the boundary delineation...
