Title:

PROCESS AND SYSTEM FOR GENERATION OF TOMOSYNTHESIS IMAGE WITH BLUR REDUCTION

Document Type and Number:

Japanese Patent JP2012115677

Kind Code:

A

Abstract:

To prevent blur when a patient moves in mammography.

A method for imaging a series of medical images by tomosynthesis with blur reduction with an imaging system (1) comprising a radiation source (24) configured to emit a total radiation dose (R_tot), a detector (251), and a control unit (3) configured to control the source (24) is provided. The method comprises positioning, with the control unit (3), the source (24) in different positions (S₁-S₉). The method also comprises emitting an individual radiation dose (R_i) by the source (24) in each of the respective positions (S₁-S₉). The method further comprises distributing, with the control unit (3), the total radiation dose (R_tot) among the individual radiation doses (R_i) such that the strongest individual radiation doses (R_i) are emitted by the source (24) in positions (S₁-S₅) corresponding to the beginning of an imaging session of the series of medical images.
