Extraordinary images. Specialized systems. Innovative solutions.

Ultrasound uses high-frequency sound waves to make images of organs and structures inside the body. An ultrasound machine makes images so that organs inside the body can be examined. The machine sends out high-frequency sound waves, which reflect off body structures.

Physics of Ultrasound

Diagnostic ultrasound can be further sub-divided into anatomical and functional ultrasound. Anatomical ultrasound produces images of internal organs or other structures. Therapeutic ultrasound also uses sound waves above the range of human hearing but does not produce images. Its purpose is to interact with tissues in the body such that they are either modified or destroyed. Among the modifications possible are: moving or pushing tissue, heating tissue, dissolving blood clots, or delivering drugs to specific locations in the body.

How Does an Ultrasound Machine Work?

Ultrasound imaging sonography uses high-frequency sound waves to view inside the body. Because ultrasound images are captured in real-time, they can also show movement of the body's internal organs as well as blood flowing through the blood vessels. Unlike X-ray imaging, there is no ionizing radiation exposure associated with ultrasound imaging. In an ultrasound exam, a transducer probe is placed directly on the skin or inside a body opening. A thin layer of gel is applied to the skin so that the ultrasound waves are transmitted from the transducer through the gel into the body.

Ultrasound application allows for noninvasive visualization of tissue structures. Real-time ultrasound images are integrated images resulting from reflection of organ surfaces and scattering within heterogeneous tissues. Ultrasound scanning is an interactive procedure involving the operator, patient, and ultrasound instruments. Although the physics behind ultrasound generation, propagation, detection, and transformation into practical information is rather complex, its clinical application is much simpler. Because ultrasound imaging has improved tremendously over the last decade, it can provide anesthesiologists opportunity to directly visualize target nerve and relevant anatomical structures.

How do ultrasound scans work?

At Philips, we are committed to transforming healthcare. That includes evolving ultrasound to be a more intelligent solution that enables swift and more confident decision-making, for more people in more places. Definitive : through exceptional image quality, advanced quantification, and intelligent solutions we provide information to customers to enable a more confident diagnosis. Everywhere : as care settings expand beyond the hospital, we are expanding the ability to use ultrasound in more places so more people can benefit.

Ultrasonography is a highly operator dependent imaging modality with a number of knobology variables that are under the control of the operator. Knobology is a terminology that describes the manipulation of ultrasound knobs and system controls in order to obtain the best image possible from diagnostic ultrasound. The inadequate use of knobology variables may impair image quality and can result in misdiagnosis.

Ultrasound

An ultrasound scan uses high-frequency sound waves to create images of the inside of the body. It is suitable for use during pregnancy.

Clinical Economics

Покраснев, Сьюзан сказала, что созрела довольно поздно. Чуть ли не до двадцати лет она была худой и нескладной и носила скобки на зубах, так что тетя Клара однажды сказала, что Господь Бог наградил ее умом в утешение за невзрачные внешние данные. Господь явно поторопился с утешением, подумал Беккер. Сьюзан также сообщила, что интерес к криптографии появился у нее еще в школе, в старших классах. Президент компьютерного клуба, верзила из восьмого класса Фрэнк Гут-манн, написал ей любовные стихи и зашифровал их, подставив вместо букв цифры.

 Выслушай меня, Мидж. Направь мне официальный запрос. В понедельник я проверю твою машину. А пока сваливай-ка ты отсюда домой.

Я хочу открыть этот проклятый файл и ознакомиться с созданной Танкадо программой.

Он двигался методично, обходя один ряд за другим. Наверху лениво раскачивалась курильница, описывая широкую дугу. Прекрасное место для смерти, - подумал Халохот.

Он увидел уборщика и подошел к. - Has visto a una nina? - спросил он, перекрывая шум, издаваемый моечной машиной.  - Вы не видели девушку.

    Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing.
