Abstract

An imaging device (100,200) for imaging a volume of interest (5,45) of a subject (4,44) comprises a radiation source (1) for emitting radiation (6), which is arranged for rotational movement around an axis (8) of the subject (4,44), a collimator (3) for collimating the radiation (6) at least in the axial direction of the subject (4,44) before traversing through the subject (4,44), a detector (2) for receiving the collimated radiation (11,12,13,14,15,16) that has traversed through the subject (4,44), and a control unit (7) for controlling the collimator (3) based on at least one geometry parameter that defines a geometrical relationship between the volume of interest (5,45) and the imaging device (100,200). The imaging device (100,200) provides for a reduced dose of radiation applied to the subject (4,44).
