English term or phrase:Dual Bearing Ring Gantry
Detectors are supported without counterweight on a single gantry. Each detector can be placed at independent radius when detectors are in 180 degree position. When at cardiac angle, the detector radius is preset to place the detector edges at the optimal distance. This allows the largest FOV for tomographic studies.
Gantry = a light bridgelike overhead framework for supporting a travelling crane, a light bridgelike overhead framework for supporting railroad signals
over several tracks
Oxford american Dictionary
Gantry = pórtico (do guindaste), cavalette, montante articulado ou de articulação
English Portuguese Comprehensive Technical Dictionary - Lewis L. Sell
bear, Bearing = to carry, to supporte
Bearing ring: anel de rolamento
Porém neste caso, olhando a figura na referencia abaixo pode ser concluído que o 'bearing ring' é um anel de suporte
montante de articulação com dois aneis de suporte
[PDF]Design approach for a Highly Accurate Patient Positioning System ...
... The overall PPS operating envelope is a major driver of the gantry design in that it sizes the minimum inner diameter of the front gantry bearing ring. Since the patient must be rotated 90° with respect to the gantry axis of rotation, the radius of the gantry ring must be substantially larger than the height of the patient.
A patient positioning
system (PPS), especially when used with a gantry beam, must permit proton beam entry from any oblique direction, without danger of collision with the gantry or beam shaping hardware.
Figure 2 shows a side view of the PPS in the treatment room with the Gantry.
