unified evaluative program. Demographic data were collected for all participants (patient/staff). Technologists, medical physicists, and radiation oncologists well-being was measured using the validated WRQoL-1 questionnaire, which assesses overall WRQoL as well as six subdomains. Participants were surveyed one month before, one month after, and six months after installation. Pre-planned analysis included the comparison of user staff with non-user of the MR-LINAC. Patient-reported outcomes (PROs) and satisfaction data for all treated individuals, measured using the EORTC PATSat-C33 and PATSat-7 instruments longitudinally from time of initial consult (baseline) and up to 10 years following the end of treatment, were systematically collected. Results: Overall, QoL perceptions among staff (n=43) were remarkably stable. Profession was the most consistent factor shaping results in all domains. Overall WRQoL showed that physicists generally reported the highest levels of satisfaction and well-being (3.8, SD 0.2), technologists the lowest (3.4, SD 0.5), and radiation oncologists fell in between (3.7, SD 0.5). This stratification remained stable over six months. User status introduced only modest, subdomain-specific differences. Among technologists, users reported slightly better work–life balance than their non-user peers. Users reported slightly greater perceived control, particularly among technologists, suggesting modest gains in autonomy with growing familiarity and direct involvement in implementation. Stress at Work scores showed a mild but consistent improvement across the six-month period.Among patients (n=81), longitudinal PATSat-7 scores remained stable across all follow-up points. Subscales of the PATSat-C33, corresponding to satisfaction regarding technologist, physician, and service and care organization domains, underlined consistently high satisfaction across all aspects of care.

Conclusion: Early human experience of MR-LINAC implementation at a high-volume academic center demonstrated excellent professional and patient tolerance. WRQoL remained stable, and patient satisfaction was high. The ongoing study will extend WRQoL assessment
