Ultrasound Imaging:
Ultrasound waves are sound waves of very high frequency that are inaudible to the
human ear. The rate of these waves is stated to be higher than twenty kilohertz. These waves
are used in medical studies for diagnostic purposes. Ultrasonography is used in liver
diagnosing liver cirrhosis. The liver is an internal organ of the human body. Due to the
higher frequency and wavelength of ultrasound waves, it travels through the internal tissue
barriers and produces images of the organ on the screen (Liu et al. 2017). Detailed movement
of internal organs of the human body can be visualized with the help of ultrasound waves.
These waves strike the internal organs and provide the image of the organs by reflecting on
the screen. According to Kromrey et al. (2015), liver fat can be visualized with the help of
ultrasonography. A combination of ultrasonography and infrared thermography is used in
thermal imaging of the thyroid nodules (Cetinkaya et al. 2018). Combination both the
processes is used in diagnosing kidney blockages (kidney stones) (Brisbane, Bailey and
Sorensen 2016). This is because a combination of both methods provides higher frequency
and wavelength ratios. This combination makes the process much more accurate than
singular approaches. Infrared thermography will be discussed in the e following paragraph.
Infrared Thermography:
This procedure uses temperature changes and heat generation for internal imaging
organs of the human body. The picture generated by this procedure is termed as a thermal
image. Infrared rays have a higher frequency than ultrasounds. This high value is estimated to
be 300 GHz (gigahertz), and thus, they can penetrate deep into tissues and find localized
infections. The result generated is termed as a thermogram, and this procedure can visualize
cancerous tumours. Infrared thermography is used in diagnosing several medical scenarios.

These scenarios involve the diagnosis of different cancer states. Cancer cells are difficult to
be penetrated. Therefore, due to the high frequency, these rays can travel deep into the tissues
and produce thermograms. According to Dekel et al. (2016), infrared thermography is used in
imaging the affected cells of colorectal cancer and cervical cancer. A combination of
computed tomographic (CT) scanning procedure with infrared thermography produces
accurate images of collapsed and dried tissues (Fournier et al. 2018). CT scan and X-ray
scanning procedure will be discussed next.
X-Ray and computed tomography:
Computed tomographic scanning involves the use of sharp beams of X rays to
produce images of the internal organs of the human body. The frequency of X rays are the
highest and ranges from 30 petahertz to 30 exahertz. Therefore they can travel deep into the
internal organs which are highly complicated in their structure. One of these organs is the
human brain. Brain cancers are diagnosed easily by using CT scanning procedure (Gonzalez
et al. 2016). The ray rotates around the body and provides a brief description of the condition
of the internal body structures. Brain haemorrhages can be prevented by an early diagnosis
of the organ with this procedure (Dubosh et al. 2016). As a result, it can be stated that this
method is beneficial in imaging the internal organs of the human body.
