Patients in hospital beds are often in need of nuclear medicine imaging, but that process requires disturbing the patient with transfers from the bed to the gurney to the imaging table and back again. The G-Cube mobile concept brings the imaging device to the patient, instead of the other way around. Dedicated to cardiac applications, it is mainly used to measure heart activity during blood extraction. It can be positioned everywhere, especially under a hospital bed, which makes it possible to scan patients in the prone position, without transferring them to and from the bed.
