We also know ultrasound as ultrasonography a diagnostic imaging technique based on the application of ultrasound. It is utilized to visually perceive internal body structures such as tendons, muscles, joints, internal organs, and vessels.
Its aim is often to find a source of a disease or to omit any pathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound and is widely used.
Types of Ultrasound Imaging
2D Ultrasound Imaging: cross section Two cross-section images of the scanned tissue as 2d ultrasound, this scanning is still standard for many diagnostic and obstetric situations.
3D Ultrasound Imaging : Projected into three-dimensional representations. A common use for 3d ultrasound is to provide a complete and realistic image of a developing fetus.
4D Ultrasound Imaging: By updating 3d ultrasound in rapid succession, sonographers can also create 4d ultrasound. With 4d ultrasound, the fourth dimension, time, adds movement and creates a most realistic representation of all.
Doppler Ultrasound Imaging: Testing blood flow as it moves through blood vessels is a common component of many of the ultrasound. A Doppler ultrasound analysis bounces high-frequency sound waves off blood cells in motion and records changes is the frequency of sound waves as they echo back to the transducer probe.

Diagnostic Applications of Ultrasound Imaging
Anesthesiology- Ultrasound is commonly used by anesthesiologists to guide injecting needles when placing local anesthetic solutions near nerves.
Angiology- Duplex ultrasound is used in angiology to diagnose arterial and venous disease.
Cardiology-Echocardiography an essential tool in the cardiology, to diagnose dilatation of parts of the heart and function of the heart ventricles and valves.
Emergency Medicine- Ultrasound is routinely used in the Emergency Department of patients with abdominal pain who may have gallstones or cholecystitis.
Gastroenterology/Colorectal surgery- In the case of abdominal sonography, the solid organs such as the pancreas, aorta, inferior vena cava, liver, gall bladder, bile ducts, kidneys, and spleen are imaged.
Gynecology & Obstetrics-Obstetrical sonography is commonly used during the pregnancy to check the development of a fetus.
Head and Neck Surgery/Otolaryngology- Most structures of the neck, including thyroid and parathyroid glands, lymph nodes, and salivary glands, are well-visualized by high-frequency ultrasound.
Neonatology- The ultrasound through the soft spots in the skull of a newborn infant until these completely close at about 1 year of age.
Ophthalmology- Ultrasound images of the eyes, also known as ocular ultrasonography.
Neurology-for assessing blood flow and stenoses in the carotid arteries and the big intracerebral arteries.
Pulmonology- Endobronchial Ultrasound (EBUS) is applied to standard flexible endoscopic probes used by pulmonologists to direct visualization of endobronchial lesions and lymph nodes to transbronchial needle aspiration.
Urology- The internal pelvic sonogram is performed either transvaginally ( woman) or transrectally ( man). It is used to diagnose and higher frequencies, to treat (break up) kidney stones (nephrolithiasis).
Musculoskeletal- Ultrasound is an alternative to x-ray imaging in detecting fractures of the wrist, elbow and the shoulder for patients up to 12 years.
Most Popular Brand Ultrasound Machine
While you may know about ultrasound machines or how to operate, many people are not entirely aware of what goes into picking up one. As with any product, there are certain things you need to consider and keep in mind.
First, you need to think about the features you need and want in an ultrasound machine. If all you need is a basic unit that can serve multiple purposes, the features you want will differ vastly from someone who requires a specific machine. Considerations include whether you need a two- or three-dimensional images. You also want to print out your images and store them, features that handle differently by different devices. Figure out all the features before looking into specific models.
