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.
Description
technical field [0001] The present disclosure relates generally to ultrasound imaging, and in particular to generating grating lobe minimized ultrasound images. For example, an ultrasound medical imaging device may include an array of acoustic elements configured to acquire ultrasound data in communication with a processor configured to process the acquired ultrasound data based on a plurality of subapertures generated using the array. Background technique [0002] Intravascular ultrasound (IVUS) imaging is widely used in interventional cardiology as a diagnostic tool to assess diseased vessels in the body, such as arteries, to determine the need for treatment, guide intervention and / or assess its effectiveness . An IVUS device including one or more ultrasound transducers is delivered into the vessel and directed to the region to be imaged. The transducer emits ultrasound energy in order to create an image of the vessel of interest. Ultrasound waves are partially reflecte...
