Various methods and systems for securing imaging systems are provided. In one embodiment, a method for an imaging system comprises monitoring usage of the imaging system in real-time while a user is controlling the imaging system, detecting that the usage of the imaging system is an abnormal usage, and performing one or more corrective actions based on the abnormal usage. In this way, an imaging system may be secured from cyber-attacks that may attempt to maliciously execute in an abnormal context while appearing legitimate to typical security controls.

Various systems and methods are provided for interventional imaging with remote processing. In one embodiment, a method for an imaging system comprises, during a scan, transmitting data to a remote computing system, controlling the imaging system according to results of remote processing of the data via the remote computing system responsive to receiving the results of the remote processing before a latency deadline, and controlling the imaging system according to results of local processing at the imaging system responsive to receive the results of the remote processing after the latency deadline. In this way, improved or enhanced images may be processed remotely and displayed to a user in real-time during an interventional procedure, and locally-processed images may be displayed if the remote processing is delayed.

A computer implemented method for estimating the volume of a medium comprising a contrast agent injected to a hollow organ through a catheter during an injection event, the method comprising the determination of the duration of injection during the injection event, the determination of the flow rate based on the procedure type, acquisition type, organ, specificities of the user controlling the injection, patient characteristics, concentration of an contrast agent in the medium, administration route, type of catheter, the size of the catheter, and/or any pre-sets provided, and the calculation an estimate for the volume of medium injected based on the duration of injection and the flow rate.

A workflow assistance system for image guided surgical procedures includes an interventional imaging system. The interventional imaging system operates to move relative to a patient and to acquire interventional images during a surgical procedure. A surveillance system is arranged about a surgical suite and produces surveillance data. A workflow controller processes the surveillance data to identify locations of clinicians, the patient, the interventional imaging system, and medical equipment within the surgical suite and provide operational commands to the interventional imaging system based upon the surveillance data.

In the present invention, a method and associated system is provided that produces a new sequence of combined X-ray/fluoro images obtained in synchrony with intravascular dataset/images. This synchronization is based on the time tags recorded at the acquisition of one dataset of the X-ray/fluoroscopic images and the intravascular images/datasets and the cardiac cycle correspondence between the combined X-ray/fluoro datasets/images. The combined X-ray/fluoro and intravascular sensor images provided in the method for each position of intravascular measurement/slice along the blood vessel allows the physician the ability to determine the planned position of the treatment, e.g., a stent, in the X-ray/fluoro images based on the intravascular images, and allows an accurate assessment of the target/lesion location in the X-ray/fluoro images during treatment.

X-ray/intravascular imaging colocation method and system

A method and apparatus for automatically estimating a correction to be made to an image deformed with respect to a sequence of images. The method includes detecting of information pixels in the images; calculation of a region of interest located in a binary mapping image made from the images; for each image, search in the image, for the position of a mobile region that maximizes a similarity criterion to the region; and the estimated correction to be made to the image is compared with each image being the affine transformation of the mobile region moving from its found position at which similarity criterion is maximized to the region. The correction is only applied if the balance is equal to the improvement to the similarity criterion in the region of interest and the deterioration of the similarity criterion outside the region of interest is positive.

Method and apparatus for cardiac radiological examination in coronary angiography

A method and device for calibrating images acquired by radiography comprising an X-ray source, an image acquisition, a support placed between the source and the image acquisition, on which support an object to be X-rayed is intended to be positioned. A region of interest, in which the object is likely to be found, is determined between the support and the image acquisition, the center of gravity of this region is determined and at least one calibration factor of the image or images is determined as a function of the position thus determined.

A process for reconstructing a tridimensional image of an object moving with a substantially cyclic motion, for example the vessels of the human heart, in which, for an acquisition duration extending over several cycles of the movement of the object, an acquisitio of a plurality of initial digital radiographic images is performed using a snapshot apparatus rotating around the object. Initial images having the same temporal occurrence in the course of each cycle are selected respectively in successive cycles so as to form a group of images which is associated with this same temporal occurrence. Several different groups of initial images corresponding respectively to several different temporal occurrences are formed. An intermediate tridimensional representation of the object is reconstructed on the basis of each group of initial images and of an iterative image reconstruction algorithm. A law of spatial deformation between two intermediate tridimensional representations is formulated on the basis of the two intermediate tridimensional representations corresponding to two successive temporal occurrences, and a final tridimensional representation of the object is reconstructed on the basis of the initial images successively acquired, of the spatial deformation laws successively formulated and of an iterative image reconstruction algorithm.

Process for reconstructing a tridimensional image of a moving object

Several acquisitions of digital radiographic images of an element of interest are made, by using a moving camera rotating around the element of interest in a plane parallel to the plane of a section, a matching stage is carried out in which projected elements are located in all the acquired images, corresponding respectively to the projections of the element of interest in those acquired images. The width of each projected element is determined and the section of the element of interest is reconstructed from the different widths determined.

Method of reconstruction of a section of an element of interest

Method of reconstruction of a three-dimensional image of an element of interest comprises a phase of acquisition of digital radiographic images by rotation of an camera around the organ, a phase of marking the position of the element of interest from image to image, and a phase of reconstruction of the three-dimensional image of the element of interest from acquired images and positions of the element of interest successively located in the successive images.
