AUTOMATIC INTRALUMINAL IMAGING-BASED TARGET AND REFERENCE IMAGE FRAME DETECTION AND ASSOCIATED DEVICES, SYSTEMS, AND METHODS
Disclosed is an intraluminal imaging system that includes an intraluminal imaging catheter or guidewire configured to obtain imaging data associated with a lumen of a patient while positioned within the lumen, and a processor in communication with the intraluminal imaging catheter or guidewire. The processor is configured to generate aplurality of image frames using on the imaging data, automatically measure an anatomical feature in the image frames, identify a target frame representative of a region of interest, identify a proximal reference frame located proximal of the target frame, and identify a distal reference frame located distal of the target frame. The processor is also configured to output a single screen display including the proximal reference frame, target frame, distal reference frame, and a longitudinal representation of the lumen showing the respective positions of the proximal refernce frame, the target frame, and the distal refernce frame.
Ultrasound diagnosis apparatus for measuring and displaying elasticity of object and method of operating the same
Provided are a method and ultrasound diagnosis apparatus for measuring and displaying an elasticity of an object. The ultrasound diagnosis apparatus includes: a processor configured to obtain elasticity data of a measurement target region of an object, calculate elasticity values of a plurality of regions included in the measurement target region based on the elasticity data by using different calculating methods, and combine the calculated elasticity values of the plurality of regions to calculate a final elasticity value; and a display configured to display the final elasticity value.
Control apparatus
A control apparatus detects a misalignment between an irradiation position of a transdermal treatment device and a target irradiation position. When the misalignment is detected, the control unit stops irradiation of the transdermal treatment device or moves the irradiation position closer to the target irradiation position.
INTRALUMINAL IMAGING BASED DETECTION AND VISUALIZATION OF INTRALUMINAL TREATMENT ANOMALIES
Disclosed is an intravascular imaging system, including a processor circuit configured for communication with an intravascular imaging catheter that is sized and shaped for positioning within a lumen of a blood vessel. The processor circuit configured to receive a plurality of intravascular images obtained by the intravascular imaging catheter while the intravascular imaging catheter is positioned within the lumen, wherein the plurality of intravascular images corresponds to a plurality of locations along a length of the blood vessel. The processor is further configured to determine a measurement associated with the lumen for each image of the plurality of intravascular images, generate a curve representative of a change in the measurement along the length of the blood vessel, detect a condition of the blood vessel based on the curve, and display a graphical representation of the condition.
ELASTOGRAPHY METHOD, SYSTEM AND STORAGE MEDIUM
Disclosed are an elasticity imaging method, a system and a storage medium. The method comprises: controlling an ultrasonic probe to transmit first ultrasound waves to a target object to generate shear waves propagating in a region of interest of the target object; controlling the ultrasonic probe to transmit second ultrasonic waves to the ROI to track the shear waves propagating in the ROI and receive echoes of the second ultrasonic waves, and acquiring second ultrasonic echo data based on the echoes of the second ultrasonic waves; generating a shear wave elasticity image and a strain elasticity image based on the second ultrasonic echo data; and displaying the shear wave elasticity image and the strain elasticity image. As such, the strain elasticity data is calculated according to the shear wave detection data, to enable the combination of shear wave elasticity imaging and strain elasticity imaging.
SYSTEM AND METHOD FOR ULTRASOUND ELASTOGRAPHY AND METHOD FOR DYNAMICALLY PROCESSING FRAMES IN REAL TIME
Disclosed are a system and a method for ultrasound elastography and a method for dynamically processing frames in real time. The system includes an elasticity processing apparatus having an elasticity information detecting module for extracting elasticity information representing the elasticity of a target to be detected; a quality parameter calculating module for calculating at least a quality parameter reflecting quality of each elasticity image corresponding to the elasticity information; and a frame processing module for determining whether to output corresponding elasticity image based on the quality parameter of each elasticity image. When calculating a strain of consecutive images, the parameter reflecting the quality of each image is also computed, through which, the current elasticity image is determined whether to be displayed, thus avoiding the situation that colors of acquired successive elasticity images may vary greatly due to large difference existing in stress.
Liver disease activity estimation with ultrasound medical imaging
Ultrasound-based estimation of disease activity, such as for NAS or other activity index for NAFLD for liver disease, is provided. Ultrasound measures acoustic scatter and shear wave propagation parameters, such as measuring acoustic backscatter coefficient, shear wave velocity, and shear wave damping ratio. A score for the disease activity is determined from these scatter and shear wave propagation parameters. The physician may be assisted by relatively inexpensive and rapid ultrasound as compared to biopsy or MRI based scoring in scoring activity of a disease, such as NAFLD. Ultrasound imaging is more readily available and less expensive and MRI, and is non-invasive.
Ultrasound system with automated wall tracing
An ultrasound imaging system computes real time physiological parameters from measurements of anatomical features in ultrasound image data using a neural network to identify the location of the anatomical features. In one embodiment, cardiac parameters are computed from endocardial wall tracings in M-mode ultrasound image data that are identified by the neural network.
Analysis apparatus
An analysis apparatus includes processing circuitry configured to obtain quantitative values of a plurality of types of tissue properties relating to a region of interest of a subject, and generate a diagram of the region of interest based on the quantitative values.
Automated ultrasonic measurement of nuchal fold translucency
An ultrasonic diagnostic imaging system is used to acquire a fetal image in a sagittal view for the performance of a nuchal translucency measurement. After a fetal image has been acquired, a zoom box is positioned over the image, encompassing a region of interest. The size of the zoom box is automatically set for the user in correspondence with gestational age or crown rump length. The system automatically tracks the region of interest within the zoom box in the presence of fetal motion in an effort to maintain the region of interest within the zoom box despite movement by the fetus.
