🚀 I’m very excited to share my first publication as a first author! “Towards clinical implementation of T2-weighted cine imaging for intrafraction drift correction workflows on the 1.5T MR-Linac” Published in PhiRO - Physics and Imaging in Radiation Oncology ✅ 🔗 Full text: https://lnkd.in/eejHV_yH 🤝 This work has been a fantastic collaboration between UMC Utrecht, Elekta, and Philips to improve MRI-guided radiotherapy and enable clinicians and technicians to actually see the target itself during radiotherapy treatment delivery. 🔬 What we achieved: 1. Developed a T2-weighted cine sequence with high-quality contrast and reduced artifacts 2. Evaluated the T2-TSE-cine with the standard clinical bTFE-cine sequence in patients treated for prostate cancer, rectal cancer, and oligolymph node metastases 3. Assessed tracking quality, visual grading scores, and acoustic noise levels 💡 Conclusion: The T2-TSE-cine sequence provides comparable or improved tracking performance, lower acoustic noise levels, and greater visual confidence — benefiting both clinicians and patients. 🤝 A huge thank you to all co-authors and collaborators: Hans de Boer, Jochem van der Voort van Zyp, Nicole Vissers, Reijer Rutgers, Alberts Eveline, Jasmijn Westerhoff, Alice Couwenberg, Marieke van As-Snijder, Stefano Mandija, Edwin Versteeg, Martijn Intven, Bas Raaymakers and Astrid van Lier. And a very special thanks to Hans de Boer and Astrid van Lier for their guidance throughout the entire process! 🙏 🎥 Below: Example of a prostate cancer treatment using the T2-weighted cine sequence, showing intrafraction drift motion caused by rectal gas passing and resulting in automatic beam gating.
