However, there are a few exceptions: 1 For some scans, such as a gallbladder ultrasound, your doctor may ask that you not eat or drink for certain period of time before the exam. 2 Others, such as a pelvic ultrasound, may require a full bladder. Your doctor will let you know how much water you need to drink before the exam. Do not urinate until the exam is done. 3 Young children may need additional preparation. When scheduling an ultrasound for yourself or your child, ask your doctor if there are any specific instructions you'll need to follow.

Can ultrasound be used to check ovaries?

A special transducer is gently inserted into the vagina to get a quick look at the uterus and ovaries. Ultrasound is usually painless. However, you may experience mild discomfort as the sonographer guides the transducer over your body, especially if you're required to have a full bladder, or inserts it into your body.

How does an ultrasound transducer work?

When used in an ultrasound scanner, the transducer sends out a beam of sound waves into the body. The sound waves are reflected back to the transducer by boundaries between tissues in the path of the beam (e.g. the boundary between fluid and soft tissue or tissue and bone).

What is the purpose of Doppler ultrasound?

What is tissue repair?

The process of tissue repair is a complex series of cascaded, chemically mediated events that lead to the production of scar tissue that constitutes an effective material to restore the continuity of the damaged tissue. The process is more complex than be described here, but there are several interesting recent papers and reviews including (Wener & Grose 2003, Toumi & Best 2003, Watson 2003, 2006, Hill et al 2003, Neidlinger-Wilke et al 2002, Lorena et al 2002, Latey 2001, Velnar et al 2009, Hauser et al 2013).

What is the critical angle of the US beam?

The critical angle for US at the skin interface appears to be about 15°. If the treatment head is at an angle of 15° or more to the plane of the skin surface, the majority of the US beam will travel through the dermal tissues (i.e. parallel to the skin surface) rather than penetrate the tissues as would be expected.

How fast is the velocity of the US in a saline solution?

In a saline solution, the velocity of US is approximately 1500 m sec-1 compared with approximately 350 m sec-1 in air (sound waves can travel more rapidly in a more dense medium). The velocity of US in most tissues is thought to be similar to that in saline.

What happens to the energy levels of a wave as it passes through a material?

As the US wave passes through a material (the tissues), the energy levels within the wave will diminish as energy is transferred to the material. The energy absorption and attenuation characteristics of US waves have been documented for different tissues (see absorption section).

Ultrasound Waves

FREQUENCY – the number of times a particle experiences a complete compression/rarefaction cycle in 1 second. Typically 1 or 3 MHz.

Ultrasound Waveform

The Ultrasound beam is not uniform and changes in its nature with distance from the transducer. The US beam nearest the treatment head is called the NEAR field, the INTERFERENCE field or the Frenzel zone. The behaviour of the US in this field is far from regular, with areas of significant interference.

Thermal Effects of US

In thermal mode, US will be most effective in heating the dense collagenous tissues and will require a relatively high intensity, preferably in continuous mode to achieve this effect.

What to do if you have a frozen shoulder?

If you have shoulder pain and have been diagnosed with a frozen shoulder, your physical therapist may use ultrasound to help improve the extensibility of the tissues around your shoulder prior to performing range of motion exercises. This may help improve the ability of your shoulder to stretch.

How does ultrasound work?

Ultrasound is performed with a machine that has an ultrasound transducer (sound head). A small amount of gel is applied to the particular body part; then your physical therapist slowly moves the sound head in a small circular direction on your body.

What is Laura Campedelli?

Laura Campedelli, PT, DPT, is a physical therapist with experience in hospital-based acute care and outpatient therapy with both children and adults. Therapeutic ultrasound is a treatment modality commonly used in physical therapy. It is used to provide deep heating to soft tissues in the body.

Why is ultrasound used in the body?

Ultrasound is often used to provide deep heating to soft tissue structures in the body. Deep heating tendons, muscles, or ligaments increases circulation to those tissues, which is thought to help the healing process. Increasing tissue temperature with ultrasound is also used to help decrease pain.

What are the contraindications for ultrasound?

There are some instances where you should not use ultrasound at all. These contraindications to ultrasound may include: 1 Over open wounds 2 Over metastatic lesions or any active area of cancer 3 Over areas of decreased sensation 4 Over parts of the body with metal implants, like in a total knee replacement of lumbar fusion 5 Near or over a pacemaker 6 Pregnancy 7 Around the eyes, breasts, or sexual organs 8 Over fractured bones 9 Near or over an implanted electrical stimulation device 10 Over active epiphyses in children 11 Over an area of acute infection

What is therapeutic ultrasound?

Therapeutic ultrasound is a treatment modality commonly used in physical therapy. It is used to provide deep heating to soft tissues in the body. These tissues include muscles, tendons, joints, and ligaments.

Does ultrasound help with pain?

It is thought that the ultrasound waves help improve tissue extensibility and circulation, leading to increased mobility and, ultimately, decreased pain.

How are ultrasound waves produced?

Ultrasonic waves or sound waves of a high frequency that is not audible to the human ear are produced by means of mechanical vibration in the metal treatment head of the ultrasound machine. The treatment head is then moved over the surface of the skin in the region of the injury transmitting the energy into the tissues.

How does ultrasound affect collagen?

As the ultrasound waves pass from the treatment head into the skin they cause the vibration of the surrounding tissues, particularly those that contain collagen. This increased vibration leads to the production of heat within the tissue. In most cases, this cannot be felt by the patient themselves. This increase in temperature may cause an increase in the extensibility of structures such as ligaments, tendons, scar tissue, and fibrous joint capsules. In addition, heating may also help to reduce pain and muscle spasm and promote the healing process.

What is ultrasound therapy?

Ultrasound Therapy. Ultrasound therapy has been used as an electrotherapy treatment modality by therapists over the last 50 years.It involves passing high frequency sound waves into soft tissue.

Why is ultrasound therapy important?

One of the greatest proposed benefits of ultrasound therapy is that it is thought to reduce the healing time of certain soft tissue injuries. Ultrasound is thought to accelerate the normal resolution time of the inflammatory process by attracting more mast cells to the site of injury.

Why do you put ultrasound gel on your skin?

When sound waves come into contact with air it causes a dissipation of the waves, and so a special ultrasound gel is placed on the skin to ensure maximal contact between the treatment head and the surface of the skin and to provide a medium through with the sound waves can travel. Ultrasound can also be applied underwater which is also a medium ...

How long does it take for an ultrasonic to work?

This is moved continuously over the skin for approximately 3-5 mins. Treatments may be repeated 1-2 times daily in more acute injuries and less frequently in chronic cases.

Why use lower frequency?

Simply speaking lower frequency application provides a greater depth of penetration and so is used in cases where the injured tissue is suspected to be deeply situated. Conversely, higher frequency doses are used for structures that are closer to the surface of the skin.

How many lithotripters are there in the USA?

Over 50 lithotripter devices have been on the USA market. Fluoroscopy is used for targeting the acoustic focus on the stone in the USA, although some lithotripters have B-mode ultrasound for targeting. The first lithotripters were electrohydraulic, using an underwater spark source and a reflector.

What is HIFU used for?

HIFU application in therapy and treatment of disease is one of the more active areas of research and development among all the non-ionizing-energy modalities such as radiofrequency, lasers, and microwaves. For example, HIFU is under investigation for therapeutic modulation of nerve conductance (Foley et al. 2008).

What is ultrasound assisted liposuction?

Another procedure, ultrasound assisted liposuction, is widely used in cosmetic surgery for the purpose of removing excessive fat tissue (Mann et al. 2008). The mechanism of action apparently involves cavitational fat cell break up with removal of the fat emulsion by suction through the probe.

What frequency is ultrasound used for?

Low power ultrasound of about 1 MHz fre quency has been widely applied since the 1950s for physical therapy in conditions such as tendinitis or bursitis.

What are the biological effects of ultrasound?

Other potential mechanisms for biological effects of ultrasound include the direct action of the compressional, tensile, and shear stresses. In addition, second-order phenomena, which depend on transmitted ultrasound energy, include radiation pressure, forces on particles and acoustic streaming.

When was ultrasound first used in physical therapy?

Physical Therapy. Unfocused beams of ultrasound for physical therapy were the first clinical application, dating to the 1950s , which often has been referred to simply as “therapeutic ultrasound” (Robertson and Baker, 2001). This modality now typically has a base unit for generating an electrical signal and a hand-held transducer.

How long does a flat transducer therapy last?

Therapy involves multiple treatments of 20 min each day by applying the large flat transducer to the site of injury and continuing treatment for periods of months. Although the process appears to be safe and effective, the therapy is slow and its use is predominantly limited to management of non-healing fractures.
