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.

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.

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.

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.

A system is provided for augmenting a three-dimensional (3D) model of a heart to indicate the tissue state. The system accesses a 3D model of a heart, accesses two-dimensional (2D) images of tissue state slices of the heart, and accesses source location information of an arrhythmia. The system augments the 3D model with an indication of a source location based on the source location information. For each of a plurality of the tissue state slices of the heart, the system augments a 3D model slice of the 3D model that corresponds to that tissue state slice with an indication of the tissue state of the heart represented by the tissue state information of that tissue state slice. The system then displays a representation of the 3D model that indicates the source location of the arrhythmia and the tissue state of the heart.

For parametric ultrasound imaging with an ultrasound scanner, the values for multiple parameters are determined for tissue of a patient using ultrasound. The determination may be in response to a single activation, avoiding the user having to reconfigure and activate separately for each parameter. To assist in diagnosis, one or more indicators of quality of the measurements of the parameters are calculated and displayed to the user. To further assist in diagnosis, the measurement values for the patient are displayed relative to published or population values.

Ultrasound imaging systems for automatically identifying and saving ultrasound images relevant to a needle injection procedure, and associated systems and methods, are described herein. For example, an ultrasound imaging system includes a transducer for transmitting/receiving ultrasound signals during a needle injection procedure, and receive circuitry configured to convert the received ultrasound signals into ultrasound image data. The image data can be stored in a buffer memory. A processor can analyze the image data stored in the buffer memory to identify image data that depicts a specified injection event of the needle injection procedure, and the identified image data can be stored in a memory for archival purposes.

Systems and methods for time-varying two-dimensional (2D) color maps for visualizing images or sequences of images are disclosed. The 2D color map may include brightness values of a hue corresponding to different intensities that changes over time. In some 2D color maps, the hue used for the intensity scale may change over time while the brightness of a pixel may not. In some 2D color maps, both the hue and the brightness may change relative to intensity over time.

Provided is an ultrasound imaging apparatus for predicting fetal growth rate, including: an ultrasound probe configured to transmit ultrasound signals to a fetus and receive ultrasound echo signals reflected from the fetus; a user inputter configured to receive pregnancy information regarding a patient from a user; a communicator configured to receive, from a cloud server, fetal biometric data related to the pregnancy information regarding the patient from among fetal biometric data prestored and accumulated in the cloud server; and a controller configured to generate an ultrasound image of the fetus by using the ultrasound echo signals, measure a size of a body part of the fetus on the ultrasound image, and predict the fetal growth rate based on the measured size of the body part of the fetus and the fetal biometric data received from the cloud server.

According to various embodiments, there is provided a device including a processor configured to control a robotic system to autonomously position a transducer at a plurality of locations adjacent a subject's skull and to autonomously locate a window on the subject's skull within which an artery can be located, from which artery a signal can be returned to the transducer, the signal having an energy level exceeding a predefined threshold.
