Abstract: A portable positron emission tomography (PET) scanner includes a rotatable scan detector ring which can be rotated 90 degrees for imaging a patient in a vertical or horizontal orientation. In the vertical orientation, a patient can be standing or seating such that the aperture of the scan detector ring is raised to allow the patient to be within the scanning region and lower to perform the image scanning on the patient. In the horizontal orientation, a patient must be lying down on a platform whereby the platform is moved within the aperture of the scan detector ring to perform the image scanning on the patient. In this horizontal orientation, the scan detector ring is also stowed and secured to be moved to other scanning locations.

Abstract: A positron emission tomography (PET) scanner in which a horizontal detector ring is arranged to be moved vertically up and down by a lifting mechanism, thereby eliminating the need for a patient to be in a supine position when performing PET or other types of image scanning.
