abdominal ultrasound

Ultrasound is a unique imaging modality that can be performed quickly at the bedside with relatively compact equipment, requires little patient preparation, and has no adverse effects. This issue is dedicated to diagnostic sonography of the abdominal organs and abdominal wall, and Doppler evaluation of the abdominal vessels. It has a practical how-to-do-it focus aimed at the practicing sonographer or physician. Modern ultrasound equipment can provide exquisite imaging of the abdominal organs. Doppler plays a critical role in the evaluation of the great vessels of the abdomen, providing unique functionality for evaluating portal hypertension and hemodynamically significant arterial disease. Sonography is the first-line modality for imaging abdominal transplants, and this issue has articles dedicated to Doppler ultrasound evaluation of liver and renal allografts. Because of its real-time capability, sonography is an excellent modality for image-guided intervention.

What is Point-of-Care Ultrasonography?

Point-of-care ultrasound refers to the use of portable ultrasonography at a patient’s bedside for diagnostic (e.g., symptom or sign-based examination) and therapeutic (e.g., image-guidance) purposes. Kendall et al. defined the characteristics of point-of-care (emergency) ultrasound (Table 1). (Kendall)

Table 1: Characteristics of Point-of-Care Ultrasound

Exam is for a well-defined purpose linked to improving patient outcomes

Exam is focused and goal-directed

Exam findings are easily recognizable

The exam is easily learned

Exam is quickly performed

Exam is performed at the patient’s bedside

Point-of-care ultrasonography has the potential to save billions of dollars on an annual basis across health systems It is has the capacity to revolutionize patient care and improve procedural efficacy, decrease complications, and limit pain and suffering. Advances in ultrasound technology have fueled the emergence of point-of-care ultrasonography, including improved ease-of-use, superior image quality, and lower cost ultrasound units.
The primary barrier to future universal adoption of this operator-dependent “stethoscope of the future” is the lack of widespread, efficient, and affordable training solutions. (Frost and Sullivan, Moore) The need and demand for ultrasonography training has grown in parallel to the expanded use of ultrasound technology. 

Point-of-care ultrasonography improves healthcare. While traditional methods of performing a physical examination are of critical importance, healthcare practitioners that become skilled in the use of point-of-care ultrasonography become uniquely empowered. Higher fidelity, lower cost, and smaller (handheld) ultrasound units coupled with innovative ultrasound training solutions (by dr Haissam Aref,DMS,MSc), have created a unique opportunity. Healthcare providers, facilities, and health systems that strategically incorporate point-of-care ultrasound into clinical practice will rapidly distinguish themselves from those who refrain from incorporating this highly valuable modality.

history of ultrasound

Scientists have been fascinated by the mechanisms of acoustics, echoes and sound waves for many centuries. Numerous famous individuals, including Aristotle, Leonardo da Vinci, Galileo Galilei, Sir Isaac Newton and Leonard Euler studied these phenomena. However, it was not until 1877 that Lord Rayleigh published a description of sound as a mathematical equation in “The Theory of Sound”. A few years later Jacques and Pierre Curie discovered the piezo-electric effect, that is, an electric potential is generated when mechanical pressure is applied to a quartz crystal. (Interestingly, these findings date several years before the discovery of X-rays bConrad Roentgen 1895. ()

Around 1900, with the invention of the Diode and Triode, powerful electronic amplification became possible, leading to the development of a high frequency ultrasonic device by scientists Langévin and Chilowsky.)This machine, called ‘hydrophone’, sent and received ultrasonic signals underwater. The Titanic disaster in 1912 and World War I accelerated investigations of underwater and airborne echo- ranging systems and antisubmarine warfare research, which lead to the beginning of SONAR (Sound Navigation and Ranging) and RADAR (Radio Detection and Ranging, using electromagnetic waves). The main industrial application of ultrasonic waves in the 1930’s and 1940’s became the detection of metal flaws. 

The first application of ultrasound as a medical diagnostic tool was published in 1942 by Karl and Friederich Dussik in Vienna. The Austrian brothers attempted to locate brain tumors and the cerebral ventricles by measuring ultrasound transmission through the skull. They concluded that if imaging of the ventricles was possible, the interior of the human body could also be visualized using ultrasound. This marked the beginning of diagnostic ultrasonography in the medical field

leaving investors avoiding big buisness and bed side ultrasound

 our next 5 year plan involve leaving all investors all greedy  investor doctors and corporations  representing big radiology buisness and all investors investing for profit , this plan from 2012 to 2017   will focus on our clinic ultrascan with main interest in bed side ultrasound and focusing advertising on it   

bed side ultrasound

Bed Side Portable Ultrasound(sonar)(BSPS) is a major part of my sonography interest ,bed side portable doppler duplex (BSPD),bed side portable echo(BSPE)   the future is for BSPS  we in ultrascan are professional un  all portable ultrasound exams less cost more comfy for patients
