Abstract
A method of volume rendering includes obtaining data representative of a first composited plane of one or more anatomical structures and calculating data of a second composited plane as a function of a first composited plane. The data of the second composited plane is indicative of a measure of depth of the one or more anatomical structures along respective ray cast lines. The method also includes determining depth weighted color values between two different colorization palettes as a function of the measure of depths of the second composited plane. The determined depth weighted color values are applied to the first composited plane for producing a volume rendering image with depth weighted colorization.

A method of volume rendering using depth weighted colorization, the method comprising acts of:
- obtaining first data representative of a first composited plane of one or more opaque structures along ray cast lines, the data is selected from the one of three-dimensional (3D) ultrasound matrix arrays and real-time 3D imaging;
- calculating second data representative of a second composted plane as a function of the first composited plane indicative of root-mean square (RMS) depth of the one or more opaque structures along the respective ray cast lines;
- determining depth weighted color value between two different colonization palettes as a function of the measure of the RMS depth;
- and
- generating one or more volume rendering images with depth weighted colorization.
An apparatus comprising:
- a display;
- a computer/control unit coupled to the display, wherein the computer/control unit provides data to the display for rendering a screen view;
