Technologies are disclosed for an ultrasound scanner that may perform a needle tip detection process that may include transmitting, at a first time, ultrasonic first pulse signals. The ultrasonic first pulse signals may be configured to cause first echo signals to be produced by adjacent tissue and a needle within the tissue. The scanner may receive, upon reaching a second time that is subsequent to the first time by a predetermined delay period, the first echo signals from the needle. The scanner may generate needle tip image data corresponding to a location of a tip of the needle based on the first echo signals. The scanner may perform a tissue detection process and/or may generate a compound image that includes a visual indicator of the location of the needle tip with respect to the tissue based on the needle tip image data and tissue image data.
