The method comprises: processing at least one image of the patient's body taken by the X-ray imaging device to extract information representing the instrument, wherein the at least one image comprises the instrument; and adapting X-ray emission parameters of the X-ray imaging device, depending on the information extracted from the at least one image, to minimize the X-ray dose emitted towards the patient's body. | 02-05-2015 |
20150202021 | METHOD FOR PROCESSING IMAGES OF INTERVENTIONAL RADIOLOGY - An image processing method for interventional imaging in which a region of interest of a patient is viewed. The method comprises acquiring a succession of images of a region of interest of the patient. The method also comprises detecting and tracking, on the successive images, at least one surgical instrument introduced inside the region of interest of the patient, in order to isolate said instrument therein; and comparing two successive images on which the surgical instrument has been isolated in order to identify at least one common shape therein. The method further comprises estimating the displacement of said common shape between both of these successive images; and re-alignment processing of the different successive images depending on the thereby determined estimations of displacements, these displacement estimations being considered as corresponding to the displacement caused by the physiological movement of the patient with the exception of any other movement. | 07-23-2015 |

20100204562 | CALIBRATION PROCEDURE FOR THE RELATIVE POSITION OF A TABLE AND C-ARM ON A MEDICAL IMAGING SYSTEM - A method of calibrating a mechanical model of behaviour and movement of an interventional radiology table by moving the table over at least one degree of freedom, acquiring at least one set of images corresponding to different positions of the table and C-arm, obtaining at least one set of images of a test object from different positions, using the images of the test object to determine parameters of the mechanical model of table behaviour and movement, and combining these parameters with data given by table movement sensors so as to deduce the true relative positions of the table with respect to the medical imaging system. | 08-12-2010 |
20110135183 | PROCESS FOR THREE-DIMENSIONAL RECONSTRUCTION OF AN OBJECT FROM A SINGLE VIEW - A method for determining an orientation in space of a substantially cylindrical shaped elementary object using a radiography device comprising a source of X-rays and a detector disposed opposite the source is provided. The radiography device is arranged to record a projection image of the elementary object when the elementary object is located between the source and the detector. The method includes: determining a quantity A of X-rays absorbed by the elementary object on the projection image; and evaluating the sine of an angle θ as a function of the quantity A of absorbed X-rays, wherein the angle θ is between a longitudinal axis of the elementary object and a plane of the projection image. | 06-09-2011 |
