System and method for assessment of cardiac stroke volume and volume responsiveness
Disclosed are systems and methods using ultrasound to predict if a patient's cardiac stroke volume will increase with a fluid bolus. Ultrasound measures are taken before administering a fluid bolus, including measurement of the left ventricular outflow tract velocity time integral (LVOT VTI), and venous measurements of the internal jugular vein. Data collected from such ultrasound scan is then used to predict the patient's cardiac volume response in the event that a fluid bolus is administered to that patient.
Grating lobe artefact minimization for ultrasound images and associated devices, systems, and methods
Ultrasound imaging system, devices, and methods for minimizing grating lobe artefacts in an ultrasound image are provided. For example, an ultrasound imaging system can include an array of acoustic elements and a processor in communication with the array. The processor controls the array to activate a plurality of apertures and subapertures in a scan sequence, generate an image comprising a plurality of pixels, identify at least one subaperture of the plurality of subapertures corresponding to a reduced signal value for one or more pixels of the image, and generate a grating-lobe-minimized image based on the identified subapertures. The grating-lobe-minimized image can be output to a display or combined with the original ultrasound image to include image features lost or reduced in the grating-lobe-minimized image. The grating-lobe-minimized image advantageously reduces image artefacts and clutter to simplify ultrasound image analysis and diagnosis procedures.
