  • The need for using a Monte Carlo-based QA software
    The need for using a Monte Carlo-based QA software
    Marc-André Renaud, medical physicist, PhD Recorded: May 17 2019 60 mins
    In radiation therapy, quality assurance is not only necessary and mandatory in many countries, but crucial for the treatment of patients. As treatment plans become more complex, a higher degree of accuracy in dose delivery is essential. The Monte Carlo QA technology in clinical settings provides an independent and fast calculation.

    This webinar deals with the rationale for using a Monte Carlo-based QA software in the radiation therapy clinic. In this presentation we will discuss the types of treatment plans that a Monte Carlo-based QA system would be best utilized for.
  • Why to boost with interventional radiotherapy
    Why to boost with interventional radiotherapy
    Prof. G. Kovács Recorded: May 15 2019 49 mins
    How multi-modality (combined) interventional radiotherapy treatments can improve clinical outcomes and how to implement these.

    Elekta is dedicated to stretching the boundaries of science and technology as we develop best-in-class solutions for better patient care. Multi-modality radiation treatments combine different treatment methods to, for example, boost precision. Our speaker will explain what boost therapy can do for your facility and how to implement it.
    Join this webinar together with your peers to learn about the latest in boost radiation therapy and technology.

  • Nanoscale Raman and SPM characterization of heterogeneities in 2D materials
    Nanoscale Raman and SPM characterization of heterogeneities in 2D materials
    Dr Marc Chaigneau - AFM/Raman Product Manager Recorded: Apr 29 2019 59 mins
    Two-dimensional semiconductors, specifically the broad class of transition metal dichalcogenides (TMDs), have attracted significant attention in the research community in recent years due to the wealth of interesting and potentially applicable phenomena observed in these materials. In order to control the performance of devices based on TMDs, it is important to characterize their properties at the scale relevant to the corresponding application, which in most cases today corresponds to a few tens of nanometres.

    Conventional far-field photoluminescence (PL) and Raman imaging provide highly averaged information with spectral congestion. In contrast, the TEPL and TERS methods (tip-enhanced photoluminescence and tip-enhanced Raman spectroscopy) performed with an AFM–Raman system, not limited by diffraction, provide substantial information related to the nanoscale optical properties of 2D materials with resolution down to a few nanometres.

    In this webinar, we report on the application of scanning-probe microscopy (SPM) cross-correlated with TERS and TEPL measurements. The techniques are used to image various TMD (MoS2, WS2, MoSe2, WSe2) alloys and heterostructures, revealing detailed nanoscale features and unexpected heterogeneities. These variations in the nanoscale optical and chemical properties, correlated with the structural information obtained with SPM, can provide a better understanding of 2D TMD materials for the future development of highly efficient, flexible, lightweight optoelectronic devices.
  • Radiosurgery Now: a patient-centered approach to managing brain metastases
    Radiosurgery Now: a patient-centered approach to managing brain metastases
    Dr. Dheerendra Prasad Recorded: Apr 18 2019 60 mins
    The increasing number of diagnoses of brain metastases in asymptomatic patients – as a result of screening MRIs – has created the need for both durable control and prevention of cognitive decline in patients who are expected to have increasing median survivals. Since the mainstay of their therapy is systemic management, “Radiosurgery Now” represents the idea of immediate radiosurgery with the intent of avoiding interruption of systemic management.

    This webinar will discuss the impact of delay in radiosurgery on tumour growth and the benefits of repeat radiosurgery for the long-term preservation of cognitive function. The linear and robust rapid workflow of the Leksell Gamma Knife® Icon™ is ideally suited to this concept.
  • Robustness in radiation therapy
    Robustness in radiation therapy
    Erik Engwall and Erik Korevaar Recorded: Apr 11 2019 50 mins
    The quality of a radiation treatment plan strongly depends on the ability to deal with uncertainties originating from setup and density interpretation errors, as well as from changes in patient anatomy. The creation of robust treatment plans and the evaluation of robustness prior to delivery is therefore one of the main challenges in radiation therapy. During the first part of this webinar, Erik Engwall, chief physicist at RaySearch, presents some versatile tools to address this challenge:
    - Robust optimization with the inclusion of 4DCT images, and setup and density uncertainties;
    - Robustness evaluation over multiple error scenarios.

    In the second part, Erik Korevaar, a medical physicist at UMCG, will present how robust optimization is used in a clinical setting and discuss appropriate metrics for robustness evaluation based on previous clinical experience.

    Tami Freeman, Anna Demming and Susan Curtis Recorded: Mar 21 2019 27 mins
    Thank you for your interest in becoming a student contributor for Physics World. This webinar will provide you with an overview of Physics World and IOP Publishing, plus we will also explain how you will be able to contribute your own content to the site.
  • The Modern Management of Brain Metastases
    The Modern Management of Brain Metastases
    Arjun Sahgal MD, FRCPC, Deputy Chief of Radiation Oncology at Sunnybrook Health Sciences Odette Cancer Center Recorded: Jan 8 2019 59 mins
    During the webinar, Dr Arjun Sahgal will share his perspective on the latest trends for treating brain metastases. Dr Sahgal will examine the most recent published clinical data comparing the benefits of SRS with previous treatment techniques, and the use of the most recent technologies available. The session will explore traditional treatments with WBRT and compare some of the latest SRS techniques used to treat specific targets and their clinical outcomes. Discussion is focused on precision radiation medicine, improving outcomes and quality of life for patients.
