Abstract:
1. A device for compressing the chest of a patient while imaging the patient in an imaging system, said imaging system defining an imaging area which may encompass a portion of the patient's abdomen, thorax, neck or head, said device comprising: a platform adapted to be disposed beneath the patient's thorax while the patient is disposed within a gantry of the imaging system; a belt operably connected to the platform and adapted to extend at least partially around the chest of the patient; the belt comprising a load distributing portion adapted to extend across the patient's chest, and tensioning portions extending from the load distributing portion, and posteriorly relative to the patient; a tensioning means, disposed relative to the load distributing portion of the belt such that it is located outside of the imaging area when the patient is disposed on the platform with the belt extending around chest of the patient; and translating means for translating motion of the tensioning means into anterior/posterior tension in the tensioning portion; wherein translating means comprises spindles disposed to guide the tensioning portions on either side of the patient's body from an anterior/posterior direction to a lateral/medial direction to a superior/inferior direction, and the tensioning means comprises a linear actuator connected to the tensioning portions and aligned along the superior/inferior direction in order to pull the tensioning portions superiorly or inferiorly relative to the patient.
