Dosimetric Calibration of Radiochromic Film For Laser-accelerated Proton Beams

Bellido, P.; Seimetz, Michael; Soriano, A.; Huertas, C.; García Lopez, J.; Jimenez-Ramos, M. C:; Fernandez, B.; Conde, P.; Crespo, E.; González Martínez, Antonio Javier; Hernández, L.; Iborra, A.; Martos, F.; Moliner, L.; Rigla, J. P.; Rodríguez-Álvarez, M. J.; Sánchez, F.; Vidal San Sebastian, Luis Fernando; Benlloch Baviera, Jose María (IEEE, 2013-11-02)

[Otros] When an ultra-intense and ultra-short laser pulse interacts with solid matter a fraction of the laser pulse can be converted into kinetic energy of a beam of charged particles. Radiochromic film (RCF), widely ...
Effect of noise in CT image reconstruction using QR- Decomposition algorithm

Iborra, A.; Rodríguez-Álvarez, M. J.; Soriano, A.; Sánchez, F.; Bellido, P.; Conde, P.; Crespo, E.; González Martínez, Antonio Javier; Martos, F.; Moliner, L.; Rigla, J. P.; Seimetz, Michael; Vidal San Sebastian, Luis Fernando; Benlloch Baviera, Jose María (IEEE, 2013-11-02)

[EN] The QR-Decomposition algorithm for CT 3D image reconstruction uses a linear system of equations to model the CT system response. Linear systems have a condition number that can be used to estimate the image noise. ...
Performance Evaluation of the Dual Ring MAMMI breast PET

Soriano, A.; Sánchez, F.; Carrilero, V.; Pardo, A.; Vidal San Sebastian, Luis Fernando; Vazquez, C.; Barbera, J.; Seimetz, Michael; Rodríguez-Álvarez, M.J.; Rigla, J. P.; Moliner, L.; Iborra, A.; Hernández, L.; González Martínez, Antonio Javier; Crespo, E.; Conde, P.; Bellido, P.; Caballero, L.; Benlloch Baviera, Jose María (IEEE, 2013-11-02)

[EN] MAMMI is a dedicated breast positron emission tomograph (PET) based on monolythic LYSO crystals, with a transaxial field of view (FOV) of 170 mm. It has been upgraded by adding a second ring of detectors that extends ...
Statistical moments of scintillation light distribution analysis with dSiPMs and monolithic crystals

Conde, P.; González Martínez, Antonio Javier; Hernández, L.; Bellido, P.; Crespo, E.; Iborra, A.; Moliner, L.; Rigla, J. P.; Rodríguez-Álvarez, M.J.; Sánchez, F.; Seimetz, Michael; Soriano, A.; Vidal San Sebastian, Luis Fernando; Benlloch Baviera, Jose María (IEEE, 2013-11-02)

[EN] Monolithic scintillation crystals offer the possibility to preserve the scintillation light distribution, specially when black painted. Furthermore, the statistical moments of that distribution can provide accurate ...
Time reconstruction study using tubes of response backprojectors in List Mode algorithms, applied to amonolithic crystals based breast PET

Moliner, L.; Correcher, C.; González Martínez, Antonio Javier; Conde, P.; Crespo, E.; Hernandez, L.; Rigla, J. P.; Rodriguez-Alvarez, M. J.; Sanchez, F.; Soriano, A.; Iborra, A.; Bellido, P.; Seimetz, Michael; Vidal San Sebastian, Luis Fernando; Benlloch Baviera, Jose María (IEEE, 2013-11-02)

[EN] The LM-EM algorithm has the advantage to calculate the emission probabilities needed for the reconstruction process on the fly, without the need of a pre-calculated system matrix. The reconstruction time for this ...
Time-of-Flight Detector for the Characterisation of Laser-Accelerated Protons

Seimetz, Michael; Bellido, P.; Soriano, A.; Huertas, C.; García Lopez, J.; Jimenez-Ramos, M. C:; Fernandez, B.; Conde, P.; Crespo, E.; González Martínez, Antonio Javier; Hernández, L.; Iborra, A.; Martos, F.; Moliner, L.; Rigla, J. P.; Rodríguez-Álvarez, M.J.; Sánchez, F.; Vidal San Sebastian, Luis Fernando; Benlloch Baviera, Jose María (IEEE, 2013-11-02)

[EN] Lasers of ultra-high intensity focused on thin targets can form plasmas and release large numbers of charged particles with kinetic energies in the MeV region. The characterization of the accelerated particles requires ...
