VH-PET is a versatile PET scanner that can be configured in a conventional geometry for imaging a patient that is lying horizontally on a bed. Also, with a simple 90° rotation of the detector ring, it transforms to a novel PET scanner that can image a patient in seated position.

Vertical Mode

VH-PET™ scanner rotates horizontally to allow for imaging the heart in a seated position. It can also be used with a stationary cycle for “stressing” the patient while positioned inside the PET detector ring, scanning can start immediately after the heart reaches its peak stress, allowing for quantification of myocardial blood flow and reserve that is important for the diagnosis of microvascular disease.

Horizontal Mode

In horizontal mode, VH-PET™ is designed to be placed next to a CT scanner and its table platform. The patient moves through the CT scanner and then into the gantry of the VH-PET. The images of the CT are put into the VH-PET computer for fusion with the PET images. The detector gantry has a diameter of 80 cm and a field of view of 73 cm diameter, and axial FOV of 20 cm. It has time-of-flight resolution of 250 picoseconds and spatial resolution of 3.5 mm FWHM. A Ge-68 rotating pin is used for attenuation correction.


Prescient Imaging is actively soliciting potential clinical investigators for innovative uses of these devices. Investigator’s are required to a) await institutional review board (IRB) and Food and Drug Administration (FDA) approval before allowing any subject to participate, b) obtain informed consent from subjects, c) permit the device to be used only with subjects under the investigator’s supervision, d) report adverse reactions, e) keep accurate records, and, f) more generally, to conduct the investigation in accordance with the signed agreement with the sponsor, the investigational plan, FDA’s regulations, and whatever conditions of approval are imposed by the reviewing IRB or FDA.
