Ultrasound is primarily utilized in medical imaging for localizing tumors due to its ability to provide real-time images of soft tissues and organs. This imaging technique employs high-frequency sound waves to generate detailed images that can differentiate between various types of tissues, enabling healthcare professionals to identify the size, shape, and location of tumors effectively. By visualizing the structure and morphology of the tissues in question, ultrasound can assist in guiding biopsies as well as informing treatment planning.

In comparison, the other options represent applications where ultrasound is either not typically used or is secondary to its primary purpose. Measuring blood pressure is usually done through sphygmomanometers that assess the pressure of blood flow in arteries. Detecting broken bones primarily relies on X-rays, which provide clear images of bone structures, while ultrasound is less effective for assessing bone integrity. Monitoring heart rhythm is typically performed using electrocardiograms (ECGs), which assess the electrical activity of the heart, rather than imaging techniques like ultrasound, which focus on anatomical visualization. Thus, ultrasound's primary role in localizing tumors underscores its importance in oncology and diagnostic imaging.
