Generate, filter, select: How Plan Explorer redefines automatic planning
How automatic is your automation?
In part one of this webinar, Freddie Cardel outlines the concept of automatic plan generation with Plan Explorer and demonstrates a completely new level of automation. He explains the approach, where large numbers of high-quality treatment plans are automatically generated for defined clinical goals and combinations of treatment techniques and machines, and shows how these plans can be easily filtered and browsed to find the most suitable candidates to be evaluated.
In part two, Erik Korevaar and Roel Kierkels present the first findings of the clinical evaluation they performed at University Medical Center Groningen, the Netherlands, and describe how the center envisions the use of the tool in clinical practice.

FDA-cleared in 2017, the ZAP-X gyroscopic radiosurgery platform is the latest innovation from John Adler, inventor of the CyberKnife and professor of neurosurgery and radiation oncology at Stanford University.
Integrating a modern linear accelerator with gyroscopic mobility to deliver diverse non-coplanar beams, ZAP-X is a dedicated intracranial SRS system focused on ease-of-use, uncompromised patient safety and a world-class dose gradient.
ZAP-X is built upon a first-in-kind self-shielded design that typically eliminates the need for radiation vaults. This new capability enables simple and cost-effective departmental expansions while also making SRS delivery available in locations that were previously not feasible (for example, physicians offices, outpatient centers and satellite facilities).
Combined, ZAP-X strives to remove historical costs and complexity constraints to put SRS within reach of more providers and more patients.
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.
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.
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.
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.

A new class of radiation devices is emerging, and it has the potential to transform how cancer is treated through more precise tumor targeting and adapting treatment at the time of delivery. High-field MR-linac technology integrates the power of state-of-the-art MR imaging with precision radiation technology. It can deliver precisely-targeted radiation doses while simultaneously capturing the highest-quality MR images. This will allow clinicians to visualize tumors and the surrounding healthy tissue at any time during radiation delivery, and then adapt the treatment accordingly.
High-field MR-linac devices based on diagnostic-standard MRI technology will offer many avenues for exploring improvements in radiotherapy, such as shorter treatment regimens or targeted adaption of the treatment in real time. Also, by integrating precision radiation and MRI technologies, high-field MRI capabilities can be optimally explored to help bring personalized cancer care to radiation therapy.
During this webinar, clinical experts will share their experience with Elekta Unity.
The webinar, aimed at early career researchers, will cover a range of topics including how to choose the right journal, peer-review and publication ethics, and your open access publishing options thanks to funding agreements in Austria.
Jordan Moering, Protochips and Ray Unocic, Oak Ridge National Lab
As the imaging and analytical capabilities of the modern transmission electron microscope (TEM) have improved, it has become an increasingly vital tool to characterize and study nanoscale materials. With the advent of MEMS-based sample supports, researchers are now capable of easily heating and electrically characterizing their sample in situ, directly imaging the dynamic sample reactions occurring at the atomic scale.
For semiconductor and electrical device applications, Protochips has developed focused ion beam (FIB) tools and sample preparation workflows that enable researchers to prepare FIB lamellae directly on MEMS-based sample supports, allowing pA-level electrical characterization of their sample at atomic resolution. With the growing interest surrounding graphene and other 2D materials, in situ TEM has become increasingly utilized to accelerate the discovery of these next-generation materials. At Oak Ridge National Laboratory, researchers Xiahan Sang and Ray Unocic used in situ heating to synthesize and characterize complex structural and chemical transformations of edge defects at atomic resolution. Their work pioneered new means by which 2D materials could be engineered directly in the TEM, opening new avenues for materials development and characterization. These and other novel results in the field of material science will be presented in this webinar.

Submitting manuscripts in poor English can put researchers at a disadvantage and delay the publication of research. This session will highlight the importance of quality English writing and the need to communicate your research effectively. This session will also focus on understanding journals and the types of manuscripts they publish, so that you can identify the best type of article for your study.
Susanna Eriksson, Head of Product Management Electron Spectroscopy
During the past decade, increased attention has been shown to hard X-rays in the photoelectron spectroscopy (HAXPES) field. This is mainly due to the increased information depth enabled by the higher photon energies. Such bulk sensitive measurements could previously only be performed at dedicated synchrotron radiation facilities. The beam lines providing this type of radiation are heavily booked, so access to the experimental setups is thus limited. Higher excitation energies also enables bulk sensitive measurements of deep core levels not accessible with standard XPS.
We will present a new system featuring a monochromized X-ray source giving out Ga Ka radiation at 9.25keV and a wide acceptance angle hemispherical electron analyzer, both combined on a simple to use vacuum system. With this system, a new set of possible experiments opens up in the home laboratory: investigations of buried interfaces, in operando devices, real world samples, etc.
