Abstract
An apparatus and method for providing images of a downhole tool during drilling of a wellbore are provided. A sensor on a rotating tool occupies a number of azimuthal sectors of the wellbore which are determined by a processor. The processor determines a time during which the sensor is in each of the azimuthal sectors during each revolution of the tool and provides a depth-correlated image of the sector residence times for the tool.
