Three Questions on Ultrasound (500 words per question) Term Paper

Three Questions on Ultrasound (500 words per question) - Term Paper precedentIn the Spatial Substance Picture strategy, examines of an item ar taken from different perspectives, and then are mixed to form an averaged picture quickly. This picture gives the better representation of the item, finding all the minute details. The resulting picture is the compound picture, displaying better picture quality as compared to the traditional ultrasound examination pictures. A try of research of difference reveals that the spatial compound imaging gives better meaning for the soft-tissue of the body with reduced flicker distortions, in evaluation to the traditional top quality sonographic ultrasound examinationThe drawback of speckle reduction in compound ultrasound is overcome by the frequency compound imaging, using higher harmonics of frequencies. The conventional sonography is performed on lower harmonics, which are more probable to the speckle noise effect, thus altering the echogram information. The using of advanced harmonics in frequency compound imaging ensures that a much wider bandwidth of the transducer frequency is achieved, where the receive frequency is double the intensity of the transmitted frequency. Therefore, the echo of the transmitted sound wave that is reflected back after striking a tissue is stronger in the case of frequency compound imaging, thus generating a clearer doubling (Chan & Perlas, 2011).Also in the diagnosis of deeper organs and lesion, the 3D/ 4D techniques are very useful, as it has a fair and reproducible methodology. This makes it easier to get the image of the same organ at different intervals (Layyous, 2012).The multi beam technique generates quadruplex lines of the transmitted beam to be sent at once from the probe. These multiple lines then overlap when some(prenominal) beams have been sent, and carry the detailed information about the test organ. They are then separated in the reconstruction stage of the analysis wh ere all the information is dealt separately. The
