MULTIMODAL SYSTEM FOR BREAST IMAGING
A multimodal system for breast imaging includes an x-ray source, and an x-ray detector configured to detect x-rays from the x-ray source after passing through a breast. The system includes an x-ray detector translation system operatively connected to the x-ray detector so as to be able to translate the x-ray detector from a first displacement from the breast to a second displacement at least one of immediately adjacent to or in contact with the breast. The system includes an x-ray image processor configured to: receive a CT data set from the x-ray detector, the CT data set being detected by the x-ray detector at the first displacement; compute a CT image of the breast; receive a mammography data set from the x-ray detector, the mammography data set being detected by the x-ray detector at the second displacement; and compute a mammography image of the breast.
IDENTIFICATION OF A CONTRAST PHASE DEPICTED IN A MEDICAL IMAGE
There is provided a method, comprising: accessing medical images of subjects, depicting contrast phases of contrast administered to the respective subject, accessing for a first subset of the medical images, metadata indicating a respective contrast phase, wherein a second subset of the medical images are unassociated with metadata, mapping each respective contrast phase of the contrast phases to a respective time interval indicating estimated amount of time from a start of contrast administration to time of capture of the respective medical image, creating a training dataset, by labelling images of the first subset with a label indicating the respective time interval, and including the second subset as non-labelled images, and training the ML model using the training dataset for generating an outcome of a target time interval indicating estimated amount of time from the start of contrast administration, in response to an input of a target medical image.
Imaging systems and methods
Versatile, multimode radiographic systems and methods utilize portable energy emitters and radiation-tracking detectors. The x-ray emitter may include a digital camera and, optionally, a thermal imaging camera to provide for fluoroscopic, digital, and infrared thermal imagery of a patient for the purpose of aiding diagnostic, surgical, and non-surgical interventions. The emitter may cooperative with an inventive x-ray capture stage that automatically pivots, orients and aligns itself with the emitter to maximize exposure quality and safety. The combined system uses less power, corrects for any skew or perspective in the emission, allows the subject to remain in place, and allows the surgeon's workflow to continue uninterrupted.
Methods, systems, and computer readable media for processing digital subtraction angiography (DSA) and computed tomography (CT) images for reducing radiation exposure in DSA and CT subjects
A method for processing digital subtraction angiography (DSA) or computed tomography (CT) images for reduced radiation exposure to a DSA or CT subject includes receiving, as input, a plurality of captured DSA or CT image frames of a contrast agent flowing through a volume of interest in a subject. The method further includes fitting a mathematical model to measured contrast agent density of individual voxels of the captured DSA or CT image frames to produce a mathematical model of contrast agent flow across the captured DSA or CT image frames. The method further includes sampling the mathematical model of contrast agent flow for the individual voxels to produce reconstructed DSA or CT image frames. The method further includes outputting at least one of the reconstructed CT or DSA image frames.
SALVAGE DEVICE AND METHOD FOR LOCALIZING AND REMOVING A BREAST TISSUE MARKER CLIP AT SURGERY AFTER A FAILED SPECIMEN RADIOGRAM
A salvage device for localizing a tissue marker clip includes an elongate handle having a metal ball connected to its distal end, and a probe connected to a distal end of the radiopaque fiducial element. A lumen extends through at least a portion of the elongate handle, the metal ball and the probe, terminating at a distal tip of the probe. A deployable tissue engagement member is housed at least partially within the lumen and connected to a proximal switch.
SYSTEMS AND METHODS OF VISUALIZING A MEDICAL DEVICE RELATIVE TO A TARGET
Systems and methods of visualizing a current view of a tool relative to a lesion by processing current fluoroscopic images from a current fluoroscopic sweep occurring after an initial fluoroscopic sweep. The processing includes determining the locations and/or orientations of a tool and a lesion in a current 3D reconstruction of the current fluoroscopic images or in a subset of the current fluoroscopic images, generating a 3D rendering based on the locations and/or orientations of the tool and the lesion, and displaying the 3D rendering. The locations and/or orientations of the tool and the lesion may be obtained from a user interface enabling a user to mark the current locations and/or orientations in the current 3D reconstruction or in a subset of the current fluoroscopic images, or by segmenting the current 3D reconstruction or a subset of the current fluoroscopic images.
Device and method for detecting guidewire
An electronic device includes a processor configured to generate a position movement prediction field indicating prediction of a potential positional change of a branch path by a patient's biological activity for one or more branch paths based on a blood vessel image of a reference frame, correct guidewire information extracted from a blood vessel image of a target frame with respect to a catheter position of the reference frame, and select a branch path to dispose the guidewire information, among one or more branch paths of a blood vessel region based on the position movement prediction field and the corrected guidewire information; and a display configured to visualize the guidewire information on the selected branch path.
X-ray fluoroscopic imaging apparatus
An X-ray fluoroscopy imaging apparatus has a plurality of imaging equipment component members including an X-ray source, an X-ray detector, a C-arm, a table and a display unit; a input receiving element, an information element; and a control element that controls the information element to inform that the second imaging equipment component member moves when controlling the move of the first imaging equipment component member among a plurality of imaging equipment component members and moving the second imaging equipment component member while interlocked with the move of the first imaging equipment component member.
Systems, Methods and Devices for Forming Respiratory-Gated Point Cloud for Four Dimensional Soft Tissue Navigation
A surgical instrument navigation system and method of use is provided that visually simulates a virtual volumetric scene of a body cavity of a patient from a point of view of a surgical instrument residing in the cavity of the patient, wherein the surgical instrument, as provided, may be a steerable surgical catheter with a biopsy device and/or a surgical catheter with a side-exiting medical instrument, among others. Additionally, systems, methods and devices are provided for forming a respiratory-gated point cloud of a patient's respiratory system and for placing a localization element in an organ of a patient.
INTERVENTIONAL SYSTEM
The invention relates to an interventional system comprising an introduction element (4) like a catheter for being introduced into an object (9), for instance, a person. A moving unit (2) like a robot moves the introduction element within the object, wherein a tracking image generating unit (3) generates tracking images of the introduction element within the object and wherein a controller (8) controls the tracking image generating unit depending on movement parameters of the moving unit, which are indicative of the movement, such that the tracking images show the introduction element. This control can be performed very accurately based on the known real physical movement of the introduction element such that it is not necessary to, for instance, irradiate a relatively large area of the object for ensuring that the introduction element is really captured by the tracking images, thereby allowing for a reduced radiation dose applied to the object.
