An intrauterine catheter used in conjunction with an ultrasonic scanning apparatus to improve the resolution of the ultrasonic scan. The catheter consists of a catheter having an input orifice and a plurality of output orifices. A balloon substantially surrounds the entire catheter and is filled with a fluid through the catheter. A cervical sound stop is used to ensure that only the uterus is filled with the solution.
