28 February 2026 – Interview at "Investigadores por el Mundo"

I was interviewed by Antonio G. Armas for the Spanish Live Radio show "Investigadores por el Mundo". You can listen to the interview below. Thanks to IMFAHE for making it possible.

11 February 2026 – New publication on Compton imaging with a double-layer CZT camera

In our new paper, we compare imaging performance of a single vs a double layer CZT camera, demonstrated a much better angular resolution for the double layer case in Ac-225 and Cs-137.

2 October 2025 – In-vivo Ac-225 imaging with a Compton camera at WMIC 2025

In case you missed it at the World Molecular Imaging Society (WMIS) 2025 conference, we just presented our first in-vivo images of Ac-225 with a Compton camera. We imaged as little as ~30nCi uptake in a prostate tumor model.

6 June 2025 – New publication on pre-clinical imaging of Ac-225 in phantoms

Check out our new paper on imaging of Actinium-225. Actinium-225 has demonstrated to be an excellent candidate for cancer treatment with alpha particles. However, in-vivo visualization of this radionuclide is difficult with current technology. In our new work, we demonstrated with in-vitro experiments that CZT Compton cameras provide a viable solution for this challenge.

28 May 2025 – New paper alert: Exploration of dichoic filters for TOF-PET

In our new paper, we showed that dichroic filters can be used to enhance the Cherenkov/scintillation ratio in scintillator crystals (BGO and TlCl). This is a first step towards its application in TOF-PET to improve time-of-flight without compromising energy resolution.
