Radiographic Imaging System
Radiographic imaging system comprising an x-ray radiation source. Multiple radiographic imaging apparatuses, each including multiple radiation detecting elements, are arranged two-dimensionally, and configured to read charges generated in the radiation detecting elements as image data and transmit an image signal in response to a command. A console communicating with, controlling with a command the operation of, and receiving image signals from, the multiple radiographic imaging apparatuses and acquires multiple radiographing order information items indicating which of the multiple radiographic imaging apparatuses is to be used for conducting radiographing. Upon receiving the image signal from a first of the radiographic imaging apparatuses, the console determines from the multiple radiographing order information items a subsequent radiographing order item to be conducted by the first radiographic imaging apparatus, and sends a first command to the first radiographic imaging apparatus instructing it to conduct the subsequent radiographing order item.
BREAST COMPUTED TOMOGRAPHY SYSTEM
The present invention provides a breast computed tomography system in which the body motion and the pain of an examinee during capturing of images of the breast are reduced. The breast computed tomography system includes a gantry accommodating a light emitting unit that radiates light onto the breast. The gantry includes a gripper having a right gripping portion and a left gripping portion.
SYSTEM AND METHOD FOR NAVIGATING WITHIN THE LUNG
Methods and systems for navigating to a target through a patient's bronchial tree are disclosed including a bronchoscope, a probe insertable into a working channel of the bronchoscope and including a location sensor, and a workstation in operative communication with the probe and the bronchoscope, the workstation including a user interface that guides a user through a navigation plan and is configured to present a central navigation view including a plurality of views configured for assisting the user in navigating the bronchoscope through central airways of the patient's bronchial tree toward the target, a peripheral navigation view including a plurality of views configured for assisting the user in navigating the probe through peripheral airways of the patient's bronchial tree to the target, and a target alignment view including a plurality of views configured for assisting the user in aligning a distal tip of the probe with the target.
Preview Image Acquisition User Interface for Linear Panoramic Image Stitching
A system and method that allows the capture of a series of images to create a single linear panoramic image is disclosed. The method includes capturing an image, dynamically comparing a previously captured image with a preview image on a display of a capture device until a predetermined overlap threshold is satisfied, generating a user interface to provide feedback on the display of the capture device to guide a movement of the capture device, and capturing the preview image with enough overlap with the previously captured image with little to no tilt for creating a linear panorama.
ROBUST CALCIFICATION TRACKING IN FLUOROSCOPIC IMAGING
Robust calcification tracking is provided in fluoroscopic imagery. A patient with an inserted catheter is scanned over time. A processor detects the catheter in the patient from the scanned image data. The processor tracks the movement of the catheter. The processor also detects a structure represented in the data. The structure is detected as a function of movement with a catheter. The processor tracks the movement of the structure using sampling based on a previous location of the structure in the patient. The processor may output an image of the structure.
SYSTEMS AND METHODS FOR PLANAR IMAGING USING A CAMERA WITH MULTIPLE DETECTOR HEADS
An imaging system includes a rotating gantry, a bed, plural nuclear medicine (NM) imaging detectors, and a processing unit. The rotating gantry has a bore. The NM detectors are disposed about the bore of the gantry. The NM detectors each have an in-plane field of view, and are configured to pivot about a corresponding axis with respect to the gantry to change the in-plane field of view. The processing unit is configured to acquire first NM imaging information at a first gantry rotational position, with the in-plane fields of view of the NM imaging detectors parallel to a predetermined direction; actuate the gantry to rotate to a second gantry rotational position; actuate the NM imaging detectors to pivot such that the in-plane fields of view are parallel to the predetermined direction; acquire additional NM imaging information at the second gantry rotational position; and reconstruct a planar image of the object.
System and method for measuring radiotracer bolus morphology for quantitative analysis
A computer-implemented method for determining a flow rate for a given vessel includes obtaining, via a processor, dynamic three-dimensional (3D) images of a subject utilizing nuclear medicine imaging. The method also includes obtaining, via the processor, injection parameters for a radiotracer bolus injected into the subject via an automated injector. The method further includes generating, via the processor, time activity curves (TACs) for the radiotracer bolus from the 3D images. The method even further includes estimating, via the processor, the flow rate for the given vessel based on a morphology of the one or more TACs and the injection parameters.
RADIATION APPARATUS AND RADIATION SIGNAL PROCESSING METHOD USING BIPOLAR TIME-OVER-THRESHOLD METHOD
A radiation apparatus and a radiation signal processing method are provided. To elaborate, the apparatus includes an input unit including a radiation detector; an amplification unit configured to amplify a signal input through the radiation detector; a bipolar signal generation unit configured to generate a bipolar signal by converting the amplified signal; and a comparison unit configured to output a digital signal on the basis of comparison results of the bipolar signal with a preset first threshold value and a preset second threshold value. Herein, the comparison unit includes a first comparator configured to output a digital pulse in an interval where the bipolar signal is larger than the first threshold value and a second comparator configured to output a digital pulse in an interval where the bipolar signal is smaller than the second threshold value.
Scatter and random coincidence rejection
Multiple interactions, such as Compton scattering, inside a PET detector are used to predict an incident photon's direction for identifying true coincidence events versus scatter/random coincidence events by creating a cone shaped shell projection defining a range of possible flight directions for the incident photon. The disclosed techniques can be used as prior information to improve the image reconstruction process. The disclosed techniques can be implemented in a LYSO/SiPM-based layer stacked detector, which can precisely register multiple interactions' 3D position.
