  • Heat Transfer in Solids and Fluids with COMSOL Multiphysics® Heat Transfer in Solids and Fluids with COMSOL Multiphysics® Dr Robbie Balcombe Recorded: Oct 19 2016 59 mins
    Thermal characteristics must be considered in product development, for example, in systems that include temperature control combining conduction in solids and convection in fluids. In this webinar, we will explore heat transfer between solids and fluids. We will show examples that include structural thermal expansion; convection, radiation and conduction; and electromagnetic heating. A live demo will demonstrate modelling heat transfer in COMSOL Multiphysics® and creating a customized user interface, or application, based on the model. The webinar will include a Q&A session.

    - how to apply
  • Unlocking the mysteries of the formation of our solar system with CHIMERA Unlocking the mysteries of the formation of our solar system with CHIMERA Prof. Gregg Hallinan – assistant professor of astronomy, Caltech Dr Colin Coates – product manager OEM & research, Andor Tech Recorded: Sep 22 2016 61 mins
    During this webinar we will discuss the development of the Caltech High-Speed Multi-Color Camera (CHIMERA), using two Andor iXon Ultra 888 EMCCDs, for ground-based searches for occultations of sub-kilometre-sized KBOs, which it achieves through monitoring thousands of stars simultaneously.

    CHIMERA has completed 20 nights of observing in 2015 and 2016, with an additional 50 nights observing to be completed by July 2018, yielding a final data set likely to have more than 100 occultation events.

    For several years, professional astronomers have been looking to Andor as a source of extreme performance, exceptionally robust off-the-shelf detector solutions, utilized across many of the key observation sites worldwide. We will provide an overview of the key high-sensitivity, high-temporal-resolution detector technology types, used in diverse applications such as adaptive optics wavefront sensing, solar exploration, high-time-resolution astrophysics, transit exoplanet discovery, gravitational lensing and even customized guide cameras.
  • Accounting for uncertainties in RT: adaptive therapy and robust optimization Accounting for uncertainties in RT: adaptive therapy and robust optimization Niek Schreuder, Chief Medical Physicist, Provision Center for Proton Therapy, Knoxville, TN, USA, Cameron Ditty, MSc, DAB Recorded: Sep 20 2016 59 mins
    During radiation therapy, the patient’s anatomical state is not static. Many different factors contribute to a shifting picture, and it is essential to account for uncertainties in order to ensure the quality of the treatment plan.

    In the first half of this webinar, Niek Scheuder, Chief Medical Physicist, will share his experience from implementing an adaptive planning workflow with RayStation at the Provision Center for Proton Therapy.

    In the second half, Cameron Ditty, Senior Physicist, will explain the concept of robustness in RayStation, illustrating with practical examples.

    Robust optimization handles possible variations that are not sufficiently accounted for by PTV. The resulting plan maintains target coverage while reducing dose to critical structures, even if anatomical changes or positional errors occur.
  • 60 years of the medical physics revolution 60 years of the medical physics revolution Steven Meikle, Ph.D. Professor of Medical Imaging Physics The University of Sydney, Australia Recorded: Sep 13 2016 42 mins
    In the first in a series of webinars showcasing presentations from the PMB 60th Anniversary Symposium, Steven Meikle will examine the progression of medical physics over the last 60 years. He will discuss key developments in radiation therapy, cancer diagnosis and surgery, and describe some of the underlying technologies that enabled this medical physics revolution.
  • Transforming brain radiosurgery: clinical application of a novel tool Transforming brain radiosurgery: clinical application of a novel tool Dr Dheerendra Prasad MD, MCh, FACRO, medical director, radiation medicine, Roswell Park Cancer Institute, Buffalo, New York Recorded: Sep 9 2016 50 mins
    Medical doctor Dheerandra Prasad talks about clinical prospects and his clinical experience of the Leksell Gamma Knife® Icon™ for precise, frameless and frame-based stereotactic radiosurgery of the brain.

    Leksell Gamma Knife Icon combines the unprecedented accuracy of Gamma Knife with integrated immobilization, workflow and imaging technologies to provide even greater clinical flexibility for brain radiosurgery. This is due to a number of advancements, including on-board cone beam computer tomography, a thermoplastic mask system and an infrared-based high-definition motion-management system for patient tracking during treatment, which provide the opportunity to perform frameless and fractionated radiosurgery, as well as frame-based and single-session treatments, and to perform online adaptive planning.

    Based on his experience as a radiation oncologist and a neurosurgeon, Dr Prasad discusses how these novel features of Gamma Knife Icon have opened up the possibility of extending Gamma Knife treatment to more patients and new indications. He will explain how the on-board CBCT imaging capabilities of Gamma Knife Icon have improved imaging workflows for both frame-based and frameless treatments at his clinic, and how the thermoplastic mask system has enabled him to treat targets outside the range of frame fixation. He also will describe how the ability to fractionate treatments has allowed him to expand his case mix, for example to patients with tumours that are situated close to critical structures, allowing such patients to benefit from the superior dosimetry of Gamma Knife.

    Drawing from individual case studies and his personal experience, Dr Prasad will illustrate how Leksell Gamma Knife Icon is a valuable and flexible tool for brain radiosurgery and its role alongside linac-based stereotactic radiotherapy in today’s radiation oncology centres.

  • Ray Optics Simulations with COMSOL Multiphysics Ray Optics Simulations with COMSOL Multiphysics Dr Edmund Dickinson Recorded: Jun 29 2016 61 mins
    The Ray Optics Module simulates electromagnetic wave propagation when reflection and refraction are the most important effects. This is the case when the wavelength is short compared with device size. Industrial applications include common optical components such as reflectors, monochromators, lenses and polarizers.
    This webinar will introduce the tools in COMSOL Multiphysics® for analysis of geometrical optics, including ray intensity and polarization calculations; ray propagation in graded media; and multiphysics coupling to other physics such as heat transfer.
    The webinar will include a live demo and conclude with a Q&A session.
  • Geometry Optimization with COMSOL Multiphysics® Geometry Optimization with COMSOL Multiphysics® Dr Robbie Balcombe, Technical Manager, COMSOL Recorded: May 25 2016 60 mins
    For product designers, research scientists and engineers, a computational model that predicts the behaviour of a design is only the first step in the modelling process. Once a model has been solved the next step is to optimize the design. This might involve minimising the amount of material needed to safely support a structure, or maximising the throughput of a chemical in a chemical reactor. This optimization process can be automated using the Optimization Module in COMSOL Multiphysics®. You can pick one or more objective functions to be minimised, identify which modelling inputs can be varied to achieve the optimal design, and specify a set of constraints that a model must satisfy. In this webinar we will show you how to use the geometry optimization capabilities of COMSOL Multiphysics® version 5.2 to find the best designs quickly and easily. The presentation will feature a live modelling demo and finish with a Q&A session.
