On 17th October 2025, the consortium of the AIDER project, funded under the Euratom Research and Training Program, held its kick-off meeting at the Instituto de Física Corpuscular (IFIC, CSIC-UV) in Valencia. The meeting brought together the project’s consortium partners, including  a patient association from Spain, France, Germany, and Italy, to align on the project’s shared goal of developing an advanced Compton camera-based imaging tool to improve dosimetry in targeted radionuclide and alpha therapy for cancer treatment. Discussions covered the work plan, management structure, partner roles, and key milestones over the project’s four-year duration, running until August 2029. The event marked an important step in launching this collaborative effort to enhance imaging precision and ultimately improve the safety and personalization of cancer treatments.
