Reviews and News on Ultrasound Machines

There are approximately 31 million people who currently suffer from chronic back pain in the United States. Back pain can be caused by various situations, from overexertion to more serious conditions. Experts have surmised that eighty percent of adults will suffer from back pain during some period of their lifetime and it has been noted as being the most common reason for missed days at work. If back pain is undiagnosed or untreated, it can lead to a chronic condition that causes constant pain and significantly limits mobility.

Patients that have been medically diagnosed with chronic back pain and have tried rest, prescription drugs, heat and cold therapy, and acupuncture are turning to ultrasound therapy before considering surgery.
Certain treatments can effectively treat back pain and patients respond well to the treatments. Patients are now able to heal their back ailments in the comfort of their homes using portable ultrasound machines without the expense of drugs or physical therapy.

Ultrasound machine therapy treats back pain by treating the affected area with ultrasonic sound waves at a rate of a million times per second. As the sound waves penetrate the surface layers of the skin they cause the soft tissue and muscles to vibrate while producing moderate healing vibrations that relieve pain and soothe inflammation. As the tissues and muscles relax, blood flow is increased and swelling is significantly reduced. Increasing blood flow allows more oxygen to reach the tissue and tendons while removing cell waste and aiding healing.

If you are a patient that has been diagnosed with chronic back pain by a physician, and the condition is preventing you from normal daily activities such as work or playing sports, and other treatments have not provided you with pain free results, you may want to consider Ultrasound machine Therapy. Ultrasound Therapy has successfully reduced healing time for back pain patients and can end pain permanently.

As more and more medical equipment suppliers try to capitalize on the recent expansion of ultrasound applications, it can be difficult to keep up with all of the new machines that have become available. Instead of being limited to bulky and cumbersome ultrasound scanners in a hospital setting, providers and patients are benefitting from the latest Doppler imaging techniques now being used in doctors’ offices around the world.

One recent addition to modern ultrasound machines is the Acuson p50, a portable model that is built on a Microsoft Windows-based Apple MacBook platform. It is practical, stylish, and portable, with a slide-out instrument panel and high quality color Doppler imaging. Color Doppler imaging gives this machine the ability to differentiate between tissues and the MacBook platform allows for enhanced reporting and workflow optimization.

The features of the Siemens-designed Acuson p50 include spatial compounding, which improves the visual boundaries of images and improves definition. It also has a patented speckle reduction capability that complements the color Doppler tissue imaging technology. Fully mobile and portable, this unit offers up to two hours of battery-only operation as well as on-screen access to secondary controls, built-in wireless/Ethernet connectivity and CD/DVD drives.

For the most part, the p50 ultrasound machine is used in cardiology and vascular application, including stress echocardiograms, making it an excellent companion for cardiologists, general physicians and ER doctors. Also, since the p50 is housed within the framework of a MacBook Pro, it allows doctors to perform other tasks as well, including full use of the Internet, email and Microsoft Office applications. The system comes with 2 GB of RAM, a 2.0 GHz Intel Dual-Core Pentium processor and 160 GB of memory.

Just last year, insurance companies announced plans to limit coverage of mammogram screenings in women who are under 45 or who are not within a high-risk category for breast cancer. Part of the reason for this recommendation may have been motivated by the high cost of the tests, but some in the medical community believe mammograms expose patients to higher levels of radiation than necessary.

Until recently, ultrasound scanning was not used to detect cancer because it could only provide a two dimensional image of the area in question. However, the new 3-D Doppler ultrasound machines use a special technique that allows doctors to evaluate the blood flow through the major arteries of the body, as well as the veins of the arms, legs, neck and abdomen.

Mammography is still the primary diagnostic tool for finding abnormalities in the breast, but the use of ultrasound, particularly Doppler 3-D ultrasound, is in on the rise. One reason for this is the improved safety of ultrasound, and another is relative cost of the test. Plus, mammography can be less than accurate when a woman has dense, glandular breasts. Many clinicians prefer to use ultrasound machine imaging as a secondary method of determining whether an abnormality is a sold mass, a fluid filled cyst, or both. It can also show some of the area’s other unique characteristics.

In addition to the size, shape and texture of a breast abnormality, Doppler ultrasound can assess the blood supply in lesions of the breast. As a result, it is often used as a supplemental method of cancer screening for women who are at high risk for breast cancer and unable to tolerate an MRI.

An Endoscope is a long thin tube with a miniature camera lens fixed on the tip of the tube, and a light source at the other. It is inserted in the body cavity of a person in order to view the inside of the intestines, oesophagus etc, and a magnified image of the relevant area is transmitted to a viewing monitor. The Endoscopy equipment consists of a control head and a flexible long tube containing several other tubes transmitting light, air, water or even suction.

Endoscopes pertaining to the specific parts of the body are developed in order to customize the procedures with regards to ailments relating to the abdominal cavity, lungs, bladder, uterus, nasal, rectum etc. For example, a gastro scope is used to view the insides of the stomach intestines; a laparoscope is used to look in anything from the gall bladder to the women’s reproductive organs etc.

Initially endoscopic instruments were only used to take images of the organs and intestines, today, live color video can be viewed and all aspects of the affected area can be diagnosed first hand with the use of fiber optic instruments encasing thousands of mirrors and lens in a very tiny, flexible and compact tube.

With the advancement of modern technology and the development of the endoscopic equipments, these are also used to take a biopsy, suck formation of pus, and also perform surgeries such as hernia, fallopian tubal ligation, laser surgeries etc.

The patient is usually given anesthesia for sedation and also given pain killing medications to avoid soreness or discomfort. The procedure is hardly invasive, although in some cases it requires tiny incisions depending on the requirement. After the procedure the patient is kept in observation for few hours till the effect of the anesthesia wears off and is further checked for any discomforting effects or reactions.

Pulse Wave Doppler is an imaging technique based on the ultrasound imaging principle. Ultrasound images of blood flow, either by Color Flow, Power Doppler, Continuous Wave, or Pulse Wave Doppler all essentially give the movement of the blood. Using any of the methods details about the heart circulation and blood can be found. In the technique of Pulse Wave Doppler (PWD) a series of electrical pulses are transmitted to visualize the movement of blood.

The electrical pulses sent give the echoes; depending upon the echoes the blood flow is calculated. By the Doppler Effect it can be clearly differentiated among the blood vessels and the body tissues. As the echoes from the stationary type body tissues are constant and do not change from pulse to pulse while echoes from the moving objects like blood changes from time to time with every pulse. These differences in the flow can be directly measured by the time difference or in terms of the phase difference from which the Doppler Frequency is determined.

In Pulse Wave Doppler imaging the electrical signals are sent in the form of pulses. The transmission of the pulsated signal is produced by the oscillators, which changes its voltage according to the resonance frequency. Short duration pulses of the ultrasound frequency are sent with a specific frequency, which is known as pulse repetition frequency (PRF). In the duration of the pulse transmission echoes continuously returns to the receiving transducer, but all the receiving signals are not viewed. The receiving transducer has its fixed frequency to open the gate for receiving the signals. The shift in the frequency from the pulse transmission is to allow the estimation of the Doppler Frequency Shift.

Pulse Wave Doppler is a famous technique used for imaging the blood flow by the electrical pulse methods and the technique has its own instruments, which are used to measure the blood flow.

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.

Body surface area in medical terms is the measurement of the complete surface area of the human body. It is abbreviated as BSA. For many medical applications, body surface area is a better indicator of the amount of the mass present against the body weight. These surface areas are affected by abnormal adipose mass.

When a cardiac ultrasound procedure is conducted on a patient with aortic stenosis with out the correct calculated body surface area, it can result in misdiagnosis of the seriousness of the patient’s aortic or other cardio condition. It is just common sense that the body surface area calculation of the patient will establish what the correct size for the individual’s aortic valve must be.

At a presentation of the American Society of Echocardiography, the results of a study that was conducted showed the importance of not only considering the size of the aortic valve area when making an assessment of the seriousness of aortic stenosis. Another commonly neglected important factor that contributes to the correctness of the procedure is the body surface area calculation, that plays an integral part when making use of this type of ultrasound technology in a procedure.

This particular study unwrapped the fact that when a corrective procedure with respect to aortic stenosis are not performed with the correct body surface area calculated for the specific individual, the wrong calculated valve area will obviously result in the under diagnosis of the severity of the aortic stenosis condition and will have even more severe results.

BSA is determined by recording a patient’s height and weight with the appropriate medical equipment. There are various types of formulas used for the calculation of the approximate body surface areas. Depending upon some constant scaling factor and the ratios of the height and weight, the surface area of the body is calculated.

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.
