Ultrasound analysis method and device

A system, comprising:

• a catheter with one or more imaging elements configured to capture a plurality of frames during a pullback of the catheter through a blood vessel, wherein a frame of the plurality of frames comprises a plurality of radial scan lines;
• and
• a processor operably coupled with the catheter, wherein the processor is configured to:
• process the plurality of radial scan lines for the plurality of frames into a set of maximum intensity pixel values;
• providing the set of maximum intensity pixel values to a neural network as an input, wherein the neural network is trained using a sample set of maximum intensity pixel values and training output data indicating a presence or non-presence of an object;
• generate, as an output of the neural network, a set of numerical probability values distinct from the set of maximum intensity pixel values, wherein, for the frame, a numerical probability value is representative of a likelihood that a natural intravascular object is present at a location along a length of the blood vessel, wherein the natural intravascular object comprises at least one of at least one of an anatomical structure or a pathology;
• and
• provide, to a display, an output comprising a region along the length of the blood vessel where the natural intravascular object is present.
