A comparison of the computed tomography and ultrasound imaging techniques were studied by using the 2015 radiological data of Rasheed Shekoni Specialist Hospital, DutseJigawa State. Based on this research, the mean data of the computed tomography was found and calculated to be 27.83 and that of the ultrasound one was 161.42 with a difference of 133.59 between them. This indicated that the enrolment of ultrasound imaging is much greater than that of computed tomography. And it is because computed tomography involves the use of ionizing radiation (X-ray) which is hazardous to the human body. But ultrasound imaging involves the use of high-frequency sound that has no any advert to the human body.Besides, it was equally shown that the common examinations related to computed tomography and ultrasound imaging are; Abdominal imaging, where 10 millisievert (mSv) in computed tomography examination is equivalent to 2.5 Mega-Hertz (MHz) in ultrasound one, Pelvic imaging, where 10 mSv is equivalent to 5 MHz, Spine (Musculoskeletal) imaging, where 1.5 mSv is equivalent to 15 MHz, and Coronary (Vascular) imaging, where 12 mSv is equivalent to 5 MHz, respectively. The variation in frequencies between different parts of the human body during ultrasound imaging was also analyzed using frequency, wave length, and velocity related equations[see (equation 1), and equation 2)].
