متدهاى Image Fusion
هر سنسورى مأموریت و کاربرد خاصى دارد و اغلب مطلوب ما این است که بطور همزمان در یک تصویر، قدرت تفکیک طیفى و مکانى را با هم داشته باشد چون حجم اطلاعات در یک تصویر بوسیله قدرت تفکیک مکانى و طیفى سیستم تصویربردارى محدود مى گردد و اکثر سیستمهاى تصویربردارى متداول، یکى از این دو ویژگى را عرضه مى دارند، مثل سیستمهاى تصویربردارى tm,spotو... البته در کنار این سیستمها، سیستمهاى دیگرى نیز وجود دارند...
متن کاملFinite Element Model of the Liver for Computer-assisted Hepatic Tumor Ablation
Radiofrequency tumor ablation requires precise localization of the carcinoma. In a first step, a procedure for computer-assisted puncture guiding has been assessed. Intraoperative tracking of liver movements is not easy, since the structure not only moves during intervention, but also deforms. Therefore, a 3D biomechanical model has been developed to quantify liver deformations under various co...
متن کاملCurrent status of liver tumor ablation devices.
The liver is a common site of disease for both primary and metastatic cancer. Since most patients have a disease that is not amenable to surgical resection, tumor ablation modalities are increasingly being used for treatment of liver cancer. This review describes the current status of ablative technologies used as alternatives for resection, clinical experience with these technologies, currentl...
متن کاملLip Reconstruction after Tumor Ablation
Approximately 25% of all oral cavity carcinomas involve the lips, and the primary management of these lesions is complete surgical resection. Loss of tissue in the lips after resection is treated with a variety of techniques, depending on the extension and location of the defect. Here we review highly accepted techniques of lip reconstruction and some of new trials with significant clinical ...
متن کاملRadiofrequency ablation of liver tumors: quantitative assessment of tumor coverage through CT image processing
BACKGROUND Radiofrequency ablation (RFA) is one of the most promising non-surgical treatments for hepatic tumors. The assessment of the therapeutic efficacy of RFA is usually obtained by visual comparison of pre- and post-treatment CT images, but no numerical quantification is performed. METHODS In this work, a novel method aiming at providing a more objective tool for the evaluation of RFA c...
