AI solution for PET scan optimization

SubtlePET is a deep learning solution allowing nuclear medicine practices to reduce acquisition time on existing machines and/or reduce injected dose during acquisition. From a low quality image, SubtlePET corrects and returns an image of a quality equivalent to an image taken under standard acquisition conditions, directly into the radiologist reading tools.

Reduced acquisition time

SubtlePET improves quality of images taken up to 4X faster. The image returned by SubtlePET is of standard clinical quality.

Reduction of injected dose of FDG, FCH, FDOPA, Ga-PSMA…

SubtlePET improves quality of images taken with a reduced injected dose. The image returned by SubtlePET is of standard clinical quality.

Compatible with all PET scan models and supplier

SubtlePET delivers the exam directly into the radiologist’s reading tool and therefore fits seamlessly into the existing infrastructure.

Become more agile with your schedule (late delivery, machine breakdowns, etc.)

Improve patient experience


Improve comfort and patient experience by reducing time spent in the PET scan machine

Increase access to rare tracers


Improve access to rare tracers by reducing injected doses (Ga-PSMA, FCH, FDOPA …)

Save time, reassure your diagnosis and streamline your workflow with Incepto


The quality of the images improved by the Subtle tool makes them indistinguishable from images obtained by conventional means. In addition, the results are free of artifacts and lesions can be easily identified. I can already see how the tool will improve both our workflow and the patient experience.
