Abstract
A method of displaying an ultrasound image includes determining a direction of a fetus's head based on a first ultrasound image obtained by scanning a pregnant woman's body in a first direction; determining a direction of a fetus's spine based on a second ultrasound image obtained by scanning the pregnant woman's body in a second direction; determining an orientation of the fetus within the pregnant woman's body based on the directions of the fetus's head and the fetus's spine; and displaying an image representing the orientation of the fetus, together with an ultrasound image obtained by scanning the pregnant woman's body.
Claims17
A method of displaying an ultrasound image, the method comprising:
- determining a direction of a fetus, wherein the determining of the direction of the fetus includes determining a direction of the fetus's head based on a first ultrasound image obtained by scanning a pregnant woman's body in a first direction, and determining a direction of the fetus's spine based on a second ultrasound image obtained by scanning the pregnant woman's body in a second direction;
- determining an orientation of the fetus within the pregnant woman's body based on the directions of the fetus's head and the fetus's spine, wherein the orientation of the fetus is an orientation of an axis of the fetus relative to the pregnant woman's body;
- displaying an image representing the orientation of the fetus together with an ultrasound image obtained by scanning the pregnant woman's body,
- wherein the image representing the orientation of the fetus is displayed together with the ultrasound image obtained by scanning the pregnant woman's body without a mark indicating the direction of the fetus
- displaying on a screen a display marker indicating an orientation of a probe for scanning the pregnant woman's body to obtain the ultrasound image,
- wherein the determining of the orientation of the fetus comprises determining the orientation of the fetus based on the direction of the fetus's head, the direction of the fetus's spine, and the orientation of the probe, wherein a probe marker is attached to one surface of the probe, and
- wherein the scanning of the pregnant woman's body for determining the direction of the fetus's head comprises scanning the pregnant woman's body based on a position of the probe marker and a position of the display marker with respect to the first ultrasound image on the screen, and
- determining by a processor, whether the fetus's head in the first ultrasound image is located right or left with respect to the fetus's torso, and if the fetus's head detected in the first ultrasound image is oriented in a right direction, the processor determines the orientation of the fetus as corresponding to a vertex presentation of the fetus in the pregnant woman's body, and if the fetus's head detected in the first ultrasound image is oriented in a left direction, the processor determines the orientation of the fetus as corresponding to a breech presentation of the fetus in the pregnant woman's body,
- wherein the determining of the direction of the fetus's spine comprises detecting the fetus's spine and the torso of the fetus in the second ultrasound image, determining, based on the fetus's spine and the fetus's torso, an angle of rotation of the axis of the fetus with respect to a reference point, displaying the fetus's spine and the angle of rotation on the second ultrasound image, and determining the fetus's spine and an angle of rotation of the fetus between a line connecting a central point of the fetus's torso with the reference point and a line connecting the central point thereof with the fetus's spine.

- wherein the image representing the orientation of the fetus is displayed together with the ultrasound image obtained by scanning the pregnant woman's body without a mark indicating the direction of the fetus, and
- wherein the display is further configured to display on a screen a display marker indicating an orientation of a probe for scanning the pregnant woman's body to obtain the ultrasound image,
- wherein a probe marker is attached to one surface of the probe,
- wherein the at least one processor is further configured to determine the orientation of the fetus based on the direction of the fetus's head, the direction of the fetus's spine, and the orientation of the probe, and scan the pregnant woman's body based on a position of the probe marker and a position of the display marker with respect to the first ultrasound image on the screen,
- wherein the at least one processor is further configured to determine whether the fetus's head in the first ultrasound image is located right or left with respect to the fetus's torso, and if the fetus's head detected in the first ultrasound image is oriented in a right direction, the at least one processor determines the orientation of the fetus as corresponding to a vertex presentation of the fetus in the pregnant woman's body, and if the fetus's head detected in the first ultrasound image is oriented in a left direction, the at least one processor determines the orientation of the fetus as corresponding to a breech presentation of the fetus in the pregnant woman's body,
- wherein the display is further configured to display the fetus's spine and an angle of rotation of the fetus between a line connecting a central point of the fetus's torso with a reference point and a line connecting the central point thereof with the fetus's spine,
- wherein the at least one processor is further configured to detect the fetus's spine and the torso of the fetus in the second ultrasound image, and determine, based on the fetus's spine and the fetus's torso, an angle of rotation of the axis of the fetus with respect to the reference point, and
- wherein the display is further configured to display the fetus's spine and the angle of rotation on the second ultrasound image, determining the fetus's spine and the angle of rotation of the fetus between the line connecting the central point of the fetus's torso with the reference point and the line connecting the central point of the fetus's torso with the reference point and the line connecting the central point thereof with the fetus's spine.
