A medical image display apparatus comprising: a probe configured to receive a signal received from an object in response to a signal transmitted to the object, wherein a needle is attached to the probe; at least one processor configured to: obtain first medical image data based on the signal received from the object, obtain information about a first position (901, 1011), as reference information with respect to a change in a position of a needle, and a second position at which tissue from the object is extracted by the needle, based on a signal received from a sensor attached to at least one from among the probe and the needle, and determine a tissue extraction position in the first medical image data based on the information; and a display configured to display a first medical image on which the tissue extraction position is marked, the first medical image being generated from the first medical image data, wherein the at least one processor is further configured to generate a second medical image, on which the tissue extraction position is marked, from second medical image data corresponding to the object, based on a reference point corresponding to the first position in the second medical image data, wherein the second medical image is an image of a first cross section of the object corresponding to the first medical image, wherein the display is further configured to display, on the second medical image, the tissue extraction position recorded as a position relative to the reference point. a probe configured to receive a signal received from an object in response to a signal transmitted to the object, wherein a needle is attached to the probe; at least one processor configured to: obtain first medical image data based on the signal received from the object, obtain information about a first position (901, 1011), as reference information with respect to a change in a position of a needle, and a second position at which tissue from the object is extracted by the needle, based on a signal received from a sensor attached to at least one from among the probe and the needle, and determine a tissue extraction position in the first medical image data based on the information; and a display configured to display a first medical image on which the tissue extraction position is marked, the first medical image being generated from the first medical image data, wherein the at least one processor is further configured to generate a second medical image, on which the tissue extraction position is marked, from second medical image data corresponding to the object, based on a reference point corresponding to the first position in the second medical image data, wherein the second medical image is an image of a first cross section of the object corresponding to the first medical image, wherein the display is further configured to display, on the second medical image, the tissue extraction position recorded as a position relative to the reference point. obtain first medical image data based on the signal received from the object, obtain information about a first position (901, 1011), as reference information with respect to a change in a position of a needle, and a second position at which tissue from the object is extracted by the needle, based on a signal received from a sensor attached to at least one from among the probe and the needle, and determine a tissue extraction position in the first medical image data based on the information; and a display configured to display a first medical image on which the tissue extraction position is marked, the first medical image being generated from the first medical image data, wherein the at least one processor is further configured to generate a second medical image, on which the tissue extraction position is marked, from second medical image data corresponding to the object, based on a reference point corresponding to the first position in the second medical image data, wherein the second medical image is an image of a first cross section of the object corresponding to the first medical image, wherein the display is further configured to display, on the second medical image, the tissue extraction position recorded as a position relative to the reference point.
