Known as one of the safest types of diagnostic tests, ultrasound is a non-invasive method of viewing specific areas of the body. While not known to produce any harm to humans when used properly, diagnostic ultrasound should only be used by fully trained medical practitioners.

A recent trend toward “boutique” 3-D ultrasound pictures has caused some concern within the medical community because they are used on pregnant women by non-medical staffers. Whenever any type of diagnostic equipment is used outside of a medical environment, it is never considered a safe practice, but when the service is promoted to pregnant women, it is even more disturbing. Ultrasound machines may be relatively safe, but they can still have a mechanical or thermal effect on tissue, especially when a machine uses increased output.

In ultrasound scanning, “output” is the amount of energy used to obtain the desired image. With the recent introduction of 3-D Doppler imaging technologies, these machines have not been in use long enough to gage the effects of repeated use. Pulsed images that utilize “spectral Doppler” and color-flow imaging make more use of B-mode imaging. This has led some physicians to believe that ultrasound machines should not be used on pregnant women more often than medically necessary.

Regulations on these machines have not changed the ways in which they can be used in a medical setting, but they have placed the onus of responsibility on the operator of the machine, rather than the manufacturer, to ensure that a diagnostic test is done safely. This means the operator must be familiar with the scanner’s settings and understand the potential mechanical or thermal effects on human beings.

Most trained portable ultrasound technicians are taught to use the lowest output power and shortest scanning time necessary to gather the required data. There may be some situations where it is rational to use higher output, but this type of sensitivity will only come when a practitioner has been thoroughly trained on the equipment.

Ultrasound technology has advanced dramatically since it was first introduced. Now, sonographers and radiologists can view more than just a static image on a piece of film. Thanks to new 4-D volumetric scanning, they can now see organs, fetal movements and blood flow in real time on a flat screen monitor.

These advancements in ultrasound equipment have allowed cardiologists to view the flow of blood and spot a blockage before it becomes a heart attack. Ultrasound probes can also be used after delicate organ transplant surgeries for follow-up care, instead of using more invasive techniques. And as advancements continue in ultrasound technology, it is now used frequently to diagnose problems with specific organs. Sonographers can take a multiple-clip dynamic image that can later be examined by a radiologist to view cross-sections of a 3-D image.

The major differences between the ultrasound equipment of the 80’s and 90’s, and what we are seeing today, is due to the addition of color Doppler and digital imaging. This technology offers doctors the ability to view movement and transitions that occur within an organ, artery or fetus.

Even the size and scope of hospital ultrasound equipment has changed over the past twenty years. Today’s machines can be moved from one part of a hospital to another, and offer far more sophisticated imaging techniques than the ultrasound machines of the past.

An even smaller, mobile unit will soon be available, thanks to a new “analog front-end” chip. Expect to see a full range of handheld ultrasound devices that can be used in mobile lifesaving units or on-site at disaster areas. As the demand for this equipment grows, and compact probes are adapted for diagnostic and post-operative treatment, physicians expect them to be used in even more medical and surgical applications.

Color Flow Mode (CFM) is also called as Color Flow Doppler Imaging (CFD). These are the ultrasonic imaging techniques used for measuring the blood flow through the heart. They display the flow data on the 2-D echocardiography image. The technique is mainly used for determining the congenital, valvular and other forms of disease related to heart.

The color flow mode imaging is based on the Doppler Effect of the acoustics. The Doppler Effect helps to find out the blood flow from different parts of the body. It helps to identify the direction of the flow of blood. Color flow mode imaging is understandable to the common user. They avoid the displays of the complex spectral velocity structures.

In the color flow imaging different colors defines the direction of the given jet. The red color and blue colors are taken for defining the direction. The change in the hues from bright to dull depicts the change in the velocities. When there is turbulence in the blood flow a mosaic of colors is formed. Therefore a 2-D display of the blood flow is depicted by the identification of size, velocity and direction.

Red color is used to depict the flow towards the transducer and the blue color is used to depict the flow away from the transducer. Different color references can always be seen in different Doppler Imaging devices. Generally in color flow mode the color bar of black color represents zero flow.

Color flow mode is a very easy and understandable way to study the ultrasonic waves to calculate the blood flow. By making different colors as the codes to measure the flow of blood people can get easily the meaning of the reports generated. These techniques work in the normal hearing range of the humans thus are not harmful for humans.

Obstetrics is the special deal of care given to a lady and her child during her period of pregnancy, puerperium and child birth. In the obstetric exercise, the obstetric practitioners look after the pregnant woman on a regular basis to check the growth of the offspring. These obstetrics ensures that there is no ex-novo disease and no other preexisting diseases in the body of the pregnant woman which may possibly affect the baby in future.

Some of the risks which should be seen by an obstetric practitioner are pre-eclampsia, abnormal fetal presentation, abnormal placentation and intrauterine growth restriction. All such risk identification requires some special analysis of the woman on the regular basis. For example to check for pre-eclampsia, albuminuria i.e. the level of urine protein and blood pressure are checked at regular intervals.

In late pregnancies some of the fetal presentations get established like cephalic presentation which involves head first but the baby can be present buttocks first or feet first, transverse or at an oblique presentation. Some of the intrauterine growth restrictions observed by the obstetric practitioners is a general designation in which the offspring is smaller than the expected size, in this case such serious growth symptoms shows a behavior to drop off from the 50 percentile and coming above 10 percentile.

All the calculations are obtained when plotted on a fetal growth chart. Different causes can be extrinsic, relating to the problems apart from the fetus and different causes can be intrinsic, which means relating to the problems of the fetus. An obstetrician needs to check for all types of symptoms to save a child from any of the problems which may arise in future and for the pregnant lady to ensure the successful delivery. Thus for a complete growth of the child obstetrician has a big role to play.

Fetal monitors are used at hospital and medical facilities to monitor fetuses and are also available for domestic or home use. There is a bunch of such products available in the market and one needs to have a good understanding of the common features and specifications commonly available on different models in order to separate the good ones from the bad and to choose the right one, which offers extra features.

The Corometrics 145 fetal monitor from GE was exclusively designed for hospital use and is quite expensive for domestic or home use. It uses ultrasound technology such as continuous external wave Doppler with autocorrelation processing and ultrasonic signals to accurately analyze the health of the fetus based on measured parameters such as heart rate and contractions of the heart as well as uterine activity of a developing baby. The data gathered through such external interference rather than using probes or intrusive devices, can be either printed out or displayed on a digital screen for analysis.

The reason why most fetal monitors are not prescribed for home use is because they are cumbersome to use and requires an understanding of the readings that they generate. They are also quite expensive to procure and are hence most suited to hospitals and clinics.

The operations on the Corometrics 145 ultrasound machine are all exclusively performed using buttons that are easy to use and user friendly. It is often more economical to buy this device online from a medical equipment supplier than to go for a retail purchase. It comes with TOCO and US transduction and provides highly accurate readings and ultrasound FHR tracings.

The printing resolution provided by thermal linear array makes the readings easy to analyze and record. They also offer consistent uterine activity recordings and everything is done using push buttons, which makes the whole process rather simple, and user friendly.

Continuous Wave Doppler is a technique of measuring the blood flow and its velocity. It employs two piezoelectric crystals in the same ultrasound transducer; one is applied for sending the continuous signals from the transducer while the other is used for receiving the continuous signal echoes. Both the crystals are mounted at a fixed angle, slightly different for both. This ensures the security from overlapping of the transmitted signal and receiving signal.
As all the signals are continuously transmitted and echoes are received simultaneously therefore it becomes very difficult to differentiate among various signals. This is sometimes a disadvantage in the ultrasound technology. But the improvements are being made further to overcome this problem.
Continuous Wave Doppler is one of the older types of ultrasound technology and imaging technique. The main utility of the CW Doppler technique is its capability to measure accurately high blood velocities which makes it an important part of the core range of medical equipment in clinical facilities.

Ultrasound technology has allowed medical practitioners the advantage to examine inner organs of patients without any surgical intrusion into their bodies. Ultrasound machines are most commonly used for examining pregnant women, in order to safely ensure that the pregnancy is proceeding normally and without any complications.

When one really looks at the options that are available when it comes to procuring a good ultrasound machine for your medical facility, the choices narrow down to two manufacturers, GE and Philips. Though these are not the only ultrasound machine manufacturers with the technical advancements necessary to accurately and consistently visualize and determine organ volume measurements, they are the most prolific at least in churning out such equipments.

The Philips IU22 Ultrasound Machine is used for general imaging and has wide clinical application capabilities. It has a multitude of applications in different spheres of anatomical classifications including Cerebrovascular, gynecological and musculoskeletal imaging.

In terms of simplicity, user friendliness, performance and efficiency, the Philips IU22 touches new heights. It has advanced quantification features and the image quality is excellent. It allows for volume imaging and the workstation view ability is similar to that of CT and MR.

Because it renders a 3D view of the image, the more obscure details that are lost in a 2D image are perceivable and hence more critical information can be gathered from each image. The new VL13-5 volume linear array transducer on the iU22 system aids in reviewing volume imaging data for superficial applications in areas such as breast, thyroid, musculoskeletal and vascular.

Studies have shown a marked reduction in examination times due to the use of this medical equipment machine. The percentage of failed ultrasound exams are also substantially less with the use of the Philips IU22. The use of technology such as the pure wave transducer, advanced XRES and tissue aberration correction help to characterize organ features and helps improve treatment planning for breast tumors and such.
