Available in PDF, EPUB and Kindle. Book excerpt: Thermal therapies employing interstitial microwave applicators for hyperthermia or ablation are in clinical use for treatment of cancer and benign disease in various organs. However, treatment of targets in proximity to critical structures with currently available devices is risky due to unfocused deposition of energy into tissue. For successful treatment, complete thermal coverage of the tumor and margin of surrounding healthy tissue must be achieved, while precluding damage to critical structures. This thesis investigates two approaches to increase precision of microwave thermal therapy. Chapter 2 investigates a novel coaxial antenna design for microwave ablation (MWA) employing a hemi-cylinderical reflector to achieve a directional heating pattern. A proof of concept antenna with an S11 of -29 dB at 2.45 GHz was used in ex vivo experiments to characterize the antennas' heating pattern with varying input power and geometry of the reflector. Ablation zones up to 20 mm radially were observed in the forward direction, with minimal heating (less than 4 mm) behind the reflector. Chapter 3 investigates the use of magnetic nanoparticles (MNP) of varying size and geometry for enhancing microwave tissue heating. A conventional dipole, operating at 2.45 GHz and radiating 15 W, was inserted into a 20 mm radius sphere of distributed MNPs and heating measurements were taken 5 mm, 10 mm, and 15 mm radially away. A heating rate of 0.08°C/s was observed at 10 mm, an increase of 2-4 times that of the control measurement. These approaches provide strong potential for improving spatial control of tissue heating with interstitial and catheter-based microwave antennas.

Download or read book A Novel Approach to Sludge Treatment Using Microwave Technology written by Eva Kocbek and published by CRC Press. This book was released on 2022-02-28 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sludge transportation costs can represent a large fraction of the expenses associated with municipal and faecal sludge management. These costs can be mitigated through the use of thermal drying approaches to reduce the sludge volume. This thesis described the application of a novel microwave-based pilot-scale unit as an alternative technology for the sanitisation and drying of sludge from municipal wastewater treatment plants and on-site sanitation facilities. The potential economic benefits of volumetric heating, moisture levelling, and increased liquid and vapour migration from the interior to the surface of the product underpins the increasing interest in the use of microwave technology during sludge treatment processes. According to the findings of this study, these factors lead to faster processing times, improved drying rates, and a reduced physical footprint. Furthermore, microwave technology operates as a standalone treatment unit. When coupled with mechanical dewatering techniques and membrane separation technology, it can increase the reliability of the technology employed in the treatment of sludge while recovering valuable resources through an agricultural or thermochemical application such as (co-) combustion. The results of this work demonstrate the strong feasibility of applying microwave-based technology within initiatives designed to protect the environment and safeguard public health.

Download or read book Innovative Food Processing Technologies written by and published by Elsevier. This book was released on 2020-08-18 with total page 2482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food process engineering, a branch of both food science and chemical engineering, has evolved over the years since its inception and still is a rapidly changing discipline. While traditionally the main objective of food process engineering was preservation and stabilization, the focus today has shifted to enhance health aspects, flavour and taste, nutrition, sustainable production, food security and also to ensure more diversity for the increasing demand of consumers. The food industry is becoming increasingly competitive and dynamic, and strives to develop high quality, freshly prepared food products. To achieve this objective, food manufacturers are today presented with a growing array of new technologies that have the potential to improve, or replace, conventional processing technologies, to deliver higher quality and better consumer targeted food products, which meet many, if not all, of the demands of the modern consumer. These new, or innovative, technologies are in various stages of development, including some still at the R&D stage, and others that have been commercialised as alternatives to conventional processing technologies. Food process engineering comprises a series of unit operations traditionally applied in the food industry. One major component of these operations relates to the application of heat, directly or indirectly, to provide foods free from pathogenic microorganisms, but also to enhance or intensify other processes, such as extraction, separation or modification of components. The last three decades have also witnessed the advent and adaptation of several operations, processes, and techniques aimed at producing high quality foods, with minimum alteration of sensory and nutritive properties. Some of these innovative technologies have significantly reduced the thermal component in food processing, offering alternative nonthermal methods. Food Processing Technologies: A Comprehensive Review, Three Volume Set covers the latest advances in innovative and nonthermal processing, such as high pressure, pulsed electric fields, radiofrequency, high intensity pulsed light, ultrasound, irradiation and new hurdle technology. Each section will have an introductory article covering the basic principles and applications of each technology, and in-depth articles covering the currently available equipment (and/or the current state of development), food quality and safety, application to various sectors, food laws and regulations, consumer acceptance, advancements and future scope. It will also contain case studies and examples to illustrate state-of-the-art applications. Each section will serve as an excellent reference to food industry professionals involved in the processing of a wide range of food categories, e.g., meat, seafood, beverage, dairy, eggs, fruits and vegetable products, spices, herbs among others.

Download or read book Diagnosis and Treatment of Cancer using Thermal Therapies written by Citlalli J. Trujillo Romero and published by CRC Press. This book was released on 2023-10-06 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: New research is being conducted in the diagnosis and new treatments of cancer that has high efficacy and are minimally invasiveness. Artificial intelligence, bioimpedance, thermal images and nanomaterials have been used to provide early diagnosis. New treatments based on the generation of microwaves, radiofrequency, or ultrasound have been proposed in the last couple of decades. Although thermotherapies have been shown to be efficient, for them to be considered as a primary treatment, they must overcome some hurdles. One of the main challenges is to ensure applicators that point the electromagnetic or the mechanical waves at a tumor, don't affect the surrounding healthy tissues. In some cases, nanoparticles have also been designed to achieve better focus. The design of new applicators can be made by computational models based on methods such as the finite element. However, to efficiently predict the applicator’s performance, it is important that dielectric, thermal, and acoustic properties (tissue characterization) are included in the models. Not only healthy tissue, but also tumors must be characterized. Patient specific treatment planning, which consists of a 3D patient model based on medical images, can be developed to implement a safety treatment. Moreover, tissue properties as well as the applicator must be defined. Parameters such as temperature increase, and heat pattern must be evaluated to ensure patient safety and treatment success.
