Clinical Trial Summary

The "BPET prototype" is a small aperture PET scanner. The BPET prototype will be used with patients, which have just finished their regularly scheduled PET examination on a clinical whole body PET system. The radioactive tracer used for this procedure will still be active. This remaining acitivity will be used for an image acquisition with the BPET prototype without the need for an additional radioactive tracer dose.

The control intervention is be a brain PET scan as part of standard clinical routine. It will be done immediately before the scan on the BPET prototype.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Assessment of adverse events	Safety of the procedure will be assessed by documenting adverse events (description of the adverse events, number of participants)	During the imaging procedure which should last 15 minutes.
Other	Assessment of device deficiencies	Safety of the procedure will be assessed by documenting device deficiencies (description of the deficiency).	During the imaging procedure which should last 15 minutes.
Other	Identification of new risks	Safety of the procedure will be assessed by identifying and documenting any new risk.	During the imaging procedure which should last 15 minutes.
Primary	PET image of the brain	The primary outcome will be a PET image of the brain for each participant taken on BPET. It will be compared against the image taken by the conventional PET machine by a trained physician and judged by whether it could be used for diagnosis and further analysis.	1 day
Secondary	Usability (patient feedback for seat comfort)	The secondary outcome with respect to usability will be feedback from patients with respect to patient seat comfort.	1 day
Secondary	Usability (medical technologist feedback for ease of positioning)	The secondary outcome with respect to usability will be feedback from medical technologist with respect to easiness of patient positioning.	1 day
