MR-guided radiotherapy (MRgRT) systems provide excellent soft tissue imaging immediately prior to and in real time during radiation delivery for cancer treatment. However, 2D cine MRI often has limited spatial resolution due to high temporal resolution. This work applies a super resolution machine learning framework to 3.

COVID-19 is lasting longer than expected, which has a huge impact on the economy and on personal life. Each country has a different response method, and the damage scale is also distinct. This study aims to find out how COVID-19-related news was handled in the domestic media to seek ways to minimize the pandemic.

Article Synopsis
  • The study aimed to investigate how different field sizes affect the Relative Biological Effectiveness (RBE) when using carbon scanning beam irradiation for cancer treatment.
  • Researchers utilized a silicon-on-insulator microdosimeter system to measure lineal energy and found that RBE values from their measurements were consistent within 6.5% of those computed by a Treatment Planning System for varying scanned areas.
  • The findings suggest that the SOI microdosimeter could serve as a reliable quality assurance tool for evaluating RBE in carbon-pencil beam scanning radiotherapy.

While atlas segmentation (AS) has proven to be a time-saving and promising method for radiation therapy contouring, optimal methods for its use have not been well-established. Therefore, we investigated the relationship between the size of the atlas patient population and the atlas segmentation auto contouring (AC) performance. A total of 110 patients' head planning CT images were selected.

The aim of this work was to study the feasibility of proton radiography (pRad) as a patient-specific range compensator (RC) quality assurance (QA) tool and to validate its clinical utility by performing QA on RCs having three kinds of possible defects. In order to achieve pRad for a single EBT film, proton beam currents were modulated with new weighting factors, maximizing the linearity of optical-density-to-thickness ratio. Two RCs, examined to be accurately manufactured as planned, were selected to estimate the feasibility of our pRad.
