Heimdall is a project that seeks to develop a prototype to validate the potential of a portable gamma camera with a mobile multi-pinhole collimator. The gamma camera will use the latest technology in crystals (GaGG) and sensors (silicon photomultipliers), already successfully used in other Oncovision products (Sentinella, WProbe, CareMiBrain). The detector will have a useful area 4 times larger than the Sentinella camera, in order to visualize larger regions of the body and at the same time improve sensitivity.

The main goal is to have a camera with a sensitivity at least an order of magnitude higher than the current one, capable of generating an image with 3D information (at least depth) in a few seconds (< 20s) for the activity currently in use in sentinel node surgeries. It is also expected to compete with planar scintigraphy equipment by having a superior FOV, expanding the clinical indications of the current camera.

This prototype will make it possible to determine the technical feasibility, complexity and development cost of this technology. It will be possible to characterize the most important parameters (sensitivity, spatial resolution -2D and 3D-, energy resolution, uniformity, image generation time, etc…). Based on the results obtained, the development of a commercial equipment based on the developed technology and the combination with other modalities such as optics and fluorescence will be considered.

The development of the project will be supported by a grant from IVACE and co-financing from the European Regional Development Fund (ERDF), with a grant of 53,235.00 Euros.
