2 abstracts were just accepted for oral presentation at the forthcoming EANM congress:

Implementation of SPECT auto-contouring detector motion in GATE Monte Carlo simulation for 177Lu and 131I molecular radiotherapy (MRT) dosimetry.
G Kayal, M Chauvin, E Mora-Ramirez, L Struelens, M Bardiès
Generation of realistic SPECT/CT images for 177Lu dosimetry in Molecular Radiotherapy (MRT) based on Monte Carlo simulation with GATE.
​G Kayal, M Chauvin, A Vergara-Gil, N Clayton, L Struelens, M Bardiès

Congratulations Gunjan!

Realistic patient images

Gunjan Kayal simulated projections of realistic patient images after 177Lu-DOTATATE therapy.
More to come soon…

MCMA conference

Gunjan Kayal presented a talk at the MCMA conference held in Montréal, Canada (17-21 June 2019):
Modeling SPECT auto-contouring acquisition for 177Lu Molecular Radiotherapy (MRT) using new developments in GATE

Congratulations. Slides a re available upon request.

Presentation at NPL

Gunjan’s work was presented in a talk given at the European Workshop on the clinical implementation of dosimetry for Molecular Radiotherapy held at NPL (20-21 May 2019):

Monte Carlo modelling of SPECT imaging

Program and presentation are available here.

PhD Defense of Gustavo Costa

After a succesful PhD defense, Gustavo was awarded a PhD.
Congratulations Dr Costa 🙂
(Edit) Gustavo is now a Post Doc at UC Davis!

New PhD Student for Dositest

We are glad to welcome Gunjan Kayal for a PhD project centred on Dositest.
Gunjan has been recruited thanks to a collaborative project between CRCT and SCK-CEN.
She will be registered in Toulouse University and co-supervised by Manuel Bardiès and Lara Struelens. Details on the research programme can be found here.
Welcome Gunjan 🙂


We’re glad to contribute to IAEA CRP E23005.
Our contribution will be to generate simulated projections of a 177Lu-DOTATATE patient.
SPECT/CT projections will be generated based on a realistic pharmacokinetics, at different time-points.
This will be the work of a PhD student (ongoing recruitment).


The IAEA CRP E23005 started officially today.
Part of the work consists in simulating clinical images for dosimetry comparison and contributes to DosiTest.

Article accepted in Phys Med Biol

The validation of Gate for clinical dosimetry, a prerequisite for DosiTest reference absorbed dose determination has just been accepted by Phys Med Biol:

Internal dosimetry with the Monte Carlo code GATE: validation using the ICRP/ICRU female reference computational model

Daphnée Villoing, Sara Marcatili, Marie-Paule Garcia, Manuel Bardiès

Gustavo Costa to present DosiTest work

Gustavo Costa will present his work during the first SFPM Young Scientists Workshop, in Luz Saint Sauveur (21-24 September 2016).

Simulation of acquisition with a Siemens Symbia T2 applying the 177Lu-DOTATE biokinetics in the XCAT phantom
