MRgHIFU safety issue: Multi-layer protection against tissue-to-air interface heating
نویسندگان
چکیده
Introduction. MRgHIFU is a hybrid technology which aims to offer efficient and safe thermal ablation of targeted tumors or other pathological tissues, while preserving healthy surrounding structures unaltered. Theoretically MRgHIFU has no limitation regarding lesion size [1]. The main challenge is to avoid near and far field heating [2]. We demonstrate here that reflection at tissue-to-air exit interfaces may cause severe problems (e.g skin or bowel burns) and we evaluate the effectiveness of a home-made multi-layer protection against tissue-to-air interface heating.

Measurements and Modeling of Flue Height Influence on Air Pollution Emissions and Thermal Efficiency of Natural Draught Gas Fired Boilers
This paper presents and analyses results from experimental and CFD work undertaken on a 24 kW domestic natural-draught gas fired boiler. The effect of chimney height on boiler flue gases is being considered to address the need for increasing concern over environmental safety as well as saving of energy. A multi-component analysis computer (DELTA 2000 CD) is used to analyze the flue gases. 3D nu...

Introduction. MRgHIFU is a hybrid technology which aims to offer efficient and safe thermal ablation of targeted tumors or other pathological tissues, while preserving the normal surrounding structures unaltered. Theoretically MRgHIFU has no limitation on lesion size [1]. The main challenge is to avoid near and far field heating [2]. We demonstrate here that beam reflection on bones is a major ...
متن کاملSafety limitations of MR‐HIFU treatment near interfaces: a phantom validation
Magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU) is a noninvasive image-guided technique used to thermally ablate solid tumors. During treatment, ultrasound reflections from distal media interfaces can shift prescribed treatment locations. The purpose of this study was to investigate the effect of normal incidence reflections from air, acrylic (modeling bone), and rubber on...
متن کاملMR guided HIFU in Cadaver Breasts for Pre-Operative Tumor Localization of Non-Palpable Breast Tumors as an Alternative to Needle Wire Tumor Localization
Introduction Breast conservation surgery is an accepted alternative to mastectomy in patients suffering from limited stage breast cancer. Physicians are increasingly confronted with non-palpable breast lesions that are only visible on MRI. Since these tumors are non-palpable, current methods to locate them include pre-operative ultrasound, X-ray mammography, and MRI image-guided wire placement....

New concepts for protective shields for NASA’s Crew Exploration Vehicles (CEVs) and planetary probes offer improved mission safety and affordability. Hazards include radiation from cosmic rays and solar particle events, hypervelocity impacts from orbital debris/micrometeorites, and the extreme heating environment experienced during entry into planetary atmospheres. The traditional approach for ...
