Development and validation of a double focalizing magnetic spectrometer for beta spectrum measurements

Guido Haefeli, François Bochud

In the framework of the EMPIR project MetroBeta, the development and optimization of a double focalizing magnetic spectrometer have been realized in order to measure the beta spectra shape. The acquisition is designed to perform, after focalization by the ...

Irradiation in a flash: Unique sparing of memory in mice after whole brain irradiation with dose rates above 100 Gy/s

Raphaël Doenlen, François Bochud, Gael Luis Boivin

This study shows for the first time that normal brain tissue toxicities after WBI can be reduced with increased dose rate. Spatial memory is preserved after WBI with mean dose rates above 100 Gy/s, whereas 10 Gy WBI at a conventional radiotherapy dose rate ...

Mass detection on mammograms: influence of signal shape uncertainty on human and model observers

François Bochud, Cyril Castella

We studied the influence of signal variability on human and model observers for detection tasks with realistic simulated masses superimposed on real patient mammographic backgrounds and synthesized mammographic backgrounds (clustered lumpy backgrounds, CLB ...

Mammographic texture synthesis: second-generation clustered lumpy backgrounds using a genetic algorithm

François Bochud, Cyril Castella

Synthetic yet realistic images are valuable for many applications in visual sciences and medical imaging. Typically, investigators develop algorithms and adjust their parameters to generate images that are visually similar to real images. In this study, we ...

Use of Dipicolinate-Based Complexes for Producing Ion-Imprinted Polystyrene Resins for the Extraction of Yttrium-90 and Heavy Lanthanide Cations

Rosario Scopelliti, Jean-Claude Bünzli, Anne-Sophie Chauvin, François Bochud

Highly selective separation of yttrium (and lanthanides) is of interest for the design of radiopharmaceuticals, and an efficient method based on the ion-imprinting concept is proposed here. The synthesis and structural, thermodynamic and photophysical char ...

144Ce as a potential candidate for interstitial and intravascular brachytherapy

Rakesh Chawla, François Bochud

To investigate the suitability of 144Ce for both interstitial and intravascular brachytherapy applications. Monte Carlo calculations of radial dose rate distributions in water were performed for 144Ce in a spring-shaped source and compared with two commonl ...
