Introduction: This paper describes a method to improve gantry-dependent beam steering for Elekta traveling wave linear accelerators by applying the measured and filtered beam servo corrections to the existing lookup table (LUT). Beam steering has a direct influence on the treatment accuracy by affecting the beam symmetry and position. The presented method provides an improved LUT with respect to the default Elekta method to reduce treatment delivery interruptions.

Article Synopsis
- Ongoing research is essential for tracking and understanding the emergence of new SARS-CoV-2 variants, particularly as diagnostic testing declines in Australia during the COVID-19 pandemic.
- In 2023, collaborations with pathology and genomics teams allowed for the monitoring of SARS-CoV-2 variants in New South Wales through various methods, including viral culture and analysis of immune responses from a large pool of blood donations.
- Findings indicated that while existing antibodies generally neutralized many variants, specific mutations in emerging strains, particularly JN.1, suggested future challenges in controlling their spread due to enhanced transmissibility.
