Ultrasound image processing

A method of processing a plurality of ultrasound images with an image processor arrangement of an ultrasound image processing apparatus, the method comprising:

• receiving a first sequence of ultrasound images imaging an anatomical feature of interest during a first full cardiac cycle in the absence of an invasive medical device in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle;
• triggering the capture of a further sequence of ultrasound images in response to an external stimulus indicative of a particular point in a further full cardiac cycle;
• receiving the further sequence of ultrasound images imaging an anatomical feature of interest during the further full cardiac cycle in the presence of the invasive medical device in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle said invasive medical device at least partially obscuring the anatomical feature of interest, and for each ultrasound image of the further sequence:
• tracking the location of the invasive medical device in the ultrasound image;
• isolating the invasive medical device from the ultrasound image;
• and
• inserting the isolated invasive medical device into an ultrasound image of the first sequence of a corresponding phase of the cardiac cycle in the tracked location;
• and
• controlling a display device to display the first sequence of ultrasound images including the inserted invasive medical device,
• wherein each of the first sequence and further sequence of ultrasound images define a cine loop,
• and wherein the invasive medical device such as a catheter, a guide wire, and a needle, and so on.
