A joint formulation for the simultaneous groupwise registration and robust ADC estimation for abdominal diffusion weighted imaging has been published in the international journal Magnetic Resonance Imaging: "Joint Groupwise Registration and ADC Estimation in the Liver using a B-Value Weighted Metric".
Finally a picture of the whole LPI was taken! The complete team active this fall, including postdocs, PhD students and ragged old faculty.
Three members of the LPI attended the 20th International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI 2017), held in Quebec, Canada, from the 10th to the 14th September.
Last 7th July 2017 Javier Royuela defended his PhD Thesis entitled "Software solutions for two computationally intensive problems: reconstruction of dynamic MR and handling of alpha-stable distributions", getting a qualification of "Sobresaliente" and being proposed for "cum laude" distinction.
The LPI was present in April 2017 in the International Society of Magnetic Resonance in Medicine 25th Annual Meeting and Exhibition, Honolulu, HI, USA. The LPI presented the following three e-posters:
- Determination of the optimal set of b-values for ADC mapping under a Rician noise assumption
- Optimal design of motion-compensated diffusion gradient waveforms
- Cardio-Respiratory Motion Estimation for Compressed Sensing Reconstruction of Free-Breathing 2D Cine MRI
Last May 5th, the III Workshop on Information and Communication Tecnologies organised by the Higher Technical School of Telecommunication Engineering took place. This meeting was organised by and for postgraduate students in the ICT field with the purpose of sharing the advances and milestones achieved during the development of their thesis with other students and thesis directors.
The funded research project: "Isotropic cine cardiac magnetic resonance imaging, an extension to contrast-free angiography: 100% efficient reconstruction through compressive sensing and joint estimation of cardio-respiratory motion" is currently under course and we are in the process of achieving full 3D , 100% efficient, free-breathing cardiac cine with groupwise motion-compensated accelerated reconstruction. The funding institution requires us to promote this advertisement.
The LPI was present in 2017 IEEE International Symposium on Biomedical Imaging (ISBI), hold in April at Melbourne. ISBI is a joint initiative of the IEEE Signal Processing Society (SPS) and IEEE Engineering in Medicine and Biology Society (EMBS). A full communication was sent to the conference, presented in a poster session, entitled Groupwise Non-Rigid Registration on Multiparametric Abdominal DWI Acquisitions for Robust ADC Estimation: Comparison with Pairwise Approaches and Different Multimodal Metrics.
Two LPI members have recently been attending the 42th International Conference on Acoustics, Speech, and Signal Processing (ICASSP 2017) at New Orleans. One communication was presented in a poster sessions: Effect of Sampling on the Estimation of the Apparent Coefficient of Diffusion in MRI.
El profesor Gustavo Gasaneo, de la Universidad Nacional del Sur, en Bahía Blanca (Argentina), realizó una visita al LPI entre el 13 y el 18 de febrero de 2017. Además de avanzar en el trabajo científico conjunto, el profesor Gasaneo impartió dos charlas: 1) Uso de sturmians en procesos de reconstrucción de imagen médica; 2)Movimientos oculares: modelado y aplicaciones
