Background: The COVID-pandemic has challenged medical education on multiple levels. Radiation Oncology (RO) is a pivotal clinical discipline for the understanding of modern oncology concepts [1]. The following analysis aims at providing an overview of students' evaluation of RO teaching in the pre- and pandemic situation. Method(s): RO curriculum at our faculty is organized longitudinally spanning all clinical semesters which are analyzed here. Students' evaluation is mandatory and done on a 101-item Likert scale (0-100;with 0 being the best grade). Starting from summer semester 2020 onward, lectures were digitalized and digital implementation was rated on a 11-item Likert scale (-5-+5;with -5 being the best grade). Evaluation results and participant numbers between winter semester 2018/2019 and summer semester 2021 were assessed, the first three semesters being classified as "pre-pandemic" and the later three as "pandemic". Result(s): Lectures were rated with a median 18.5-21.5 for the 2nd-6th clinical semester. Comparison between pre-pandemic and pandemic semesters revealed a deterioration of 1-3 points. Median participants numbers were 63.5-89 with an increase of 12-20 in the pandemic semesters except for the 6th clinical semester. The percentage of students attending 75 % of RO lectures in one semester increased considerably (median: 41.4 % vs. 75.3 %). Digital implementation was rated with a median score of -2 to 0. Discussion(s): Differences between pre-pandemic and pandemic evaluations are consistent but small and are unlikely a sign of students' discontent. Digital formats could augment the numbers of participants as well as the percentage of presence. Digital implementation was evaluated to be average to good. Conclusion(s): Digital transfer of RO is feasible and good evaluation results are maintained. Additional concepts with a web-based learning platform and videocasts are currently being developed.

Fitts' law is a prediction model to measure the difficulty level of target selection for pointing devices. However, emerging devices and interaction techniques require more flexible parameters to adopt the original Fitts' law to new circumstances and case scenarios. We propose Index of Difficulty for Eye tracking Applications (IDEA) which integrates Fitts' law with users' feedback from the NASA TLX to measure the difficulty of target selection. The COVID-19 pandemic has shown the necessity of contact-free interactions on public and shared devices, thus in this work, we aim to propose a model for evaluating contact-free interaction techniques, which can accurately measure the difficulty of eye tracking applications and can be adapted to children, users with disabilities, and elderly without requiring the acquisition of physiological sensory data. We tested the IDEA model using data from a three-part user study with 33 participants that compared two eye tracking selection techniques, dwell-time, and a multi-modal eye tracking technique using voice commands.

PURPOSE: The coronavirus pandemic is affecting global health systems, endangering daily patient care. Hemato-oncological patients are particularly vulnerable to infection, requiring decisive recommendations on treatment and triage. The aim of this survey amongst experts on radiation therapy (RT) for lymphoma and leukemia is to delineate typical clinical scenarios and to provide counsel for high-quality care. METHODS: A multi-item questionnaire containing multiple-choice and free-text questions was developed in a peer-reviewed process and sent to members of the radiation oncology panels of the German Hodgkin Study Group and the German Lymphoma Alliance. Answers were assessed online and analyzed centrally. RESULTS: Omission of RT was only considered in a minority of cases if alternative treatment options were available. Hypofractionated regimens and reduced dosages may be used for indolent lymphoma and fractures due to multiple myeloma. Overall, there was a tendency to shorten RT rather than to postpone or omit it. Even in case of critical resource shortage, panelists agreed to start emergency RT for typical indications (intracranial pressure, spinal compression, superior vena cava syndrome) within 24â¯h. Possible criteria to consider for patient triage are the availability of (systemic) options, the underlying disease dynamic, and the treatment rationale (curative/palliative). CONCLUSION: RT for hemato-oncological patients receives high-priority and should be maintained even in later stages of the pandemic. Hypofractionation and shortened treatment schedules are feasible options for well-defined constellations, but have to be discussed in the clinical context.
