摘要：
A system (1300) for facilitating the detection of an immobilized contrast agent inmedical imaging applications is proposed. The system includes means (1303-1306) forproviding a sequence of a total number of input images obtained at corresponding acquisitioninstants by imaging a body-part (155) of a patient subjected to an administrationof a contrast agent capable of circulating within the patient and of being substantiallyimmobilized on a biological target, each input image including a plurality ofinput values each one indicative of a response to an interrogation signal of acorresponding portion of the body-part possibly including said contrast agent,and means (1309-1369) for reducing a contribution of the circulating contrastagent within the body-part in at least one selected input image； the means forreducing includes means (1309-1369) for creating a filtered image correspondingto each selected input image by replacing a set of input values of the selectedinput image with a set of corresponding filtered values, each filtered valuebeing representative of the lowest response of the corresponding portion ofthe body- part in a set of multiple input images including the selected input image,the set of multiple input images consisting of a number of input images lower thanthe total number.
