Method for acquiring morphology of a breast

摘要

An imaging method performed by a device comprising an X-ray emitting source, a receiver positioned facing the source, and a support on which a subject or organ to be imaged is positioned, the method comprises defining a first set of orientations of the source and a second set of orientations of the source, and acquiring images at the defined orientations of the source, wherein if the first set of orientations comprises an orientation that the second set of orientations does not comprise, only one image is acquired at the orientation, and if both the first set of orientations and the second set of orientations comprise the same orientation, at least two images are acquired at distinct acquisition parameters at the orientation.

1. An imaging method performed by a device comprising an X-ray emitting source, a receiver positioned facing the source, and a support on which a subject or organ to be imaged is positioned, the method comprising:
defining a first set of orientations of the source and a second set of orientations of the source; and acquiring images at the defined orientations of the source, wherein the second set of orientations comprises a number of orientations that is less than the number of orientations of the first set of orientations, wherein if the first set of orientations comprises an orientation that the second set of orientations does not comprise, only one image is acquired by X-ray emission at the orientation at acquisition parameters belonging to a first set of acquisition parameters, and if both the first set of orientations and the second set of orientations comprise the same orientation, at least two images are acquired at distinct acquisition parameters at the orientation belonging to a second set of acquisition parameters that is distinct from the first set of acquisition parameters, wherein the acquisition of images at each of the orientations of the second set of orientations is performed by X-ray emissions according to several acquisition parameters comprising:
high energy acquisition parameters belonging to the second set of acquisition parameters in order to obtain high energy images for each of the orientations of the second set of orientations; andlow acquisition parameters having a maximum energy lower than a maximum energy of the high energy acquisition parameters in order to obtain low energy images, wherein the first set of acquisition parameters comprises the low acquisition parameters for orientations belonging to both the first and to the second set of orientations, and the second set of acquisition parameters comprises the low acquisition parameters for the orientations only belonging to the second set of orientations.
