Ultrasound is applied using a transducer or applicator that is in direct contact with the patient's skin. Gel is used on all surfaces of the head to reduce friction and assist transmission of the ultrasonic waves. Therapeutic ultrasound in physical therapy is alternating compression and rarefaction of sound waves with a frequency of 0.7 to 3.3 ...
Transvenous cardiac pacing (TVP), [1] also called endocardial pacing, is a potentially life-saving intervention used primarily to correct profound bradycardia. It can be used to treat symptomatic bradycardias that do not respond to transcutaneous pacing or to drug therapy. Transvenous pacing is achieved by threading a pacing electrode through a ...
Diathermy. Diathermy is electrically induced heat or the use of high-frequency electromagnetic currents as a form of physical therapy and in surgical procedures. The earliest observations on the reactions of the human organism to high-frequency electromagnetic currents were made by Jacques Arsene d'Arsonval. [1][2][3] The field was pioneered in ...
3-052. [edit on Wikidata] Doppler echocardiography is a procedure that uses Doppler ultrasonography to examine the heart. [1] An echocardiogram uses high frequency sound waves to create an image of the heart while the use of Doppler technology allows determination of the speed and direction of blood flow by utilizing the Doppler effect.
The focused ultrasound waves generate high temperatures within smaller areas. The temperature when maintained for sufficient a period of time results in the ablation of the fibroids. The therapy procedure is guided by Magnetic Resonance Imaging (MRI) with real time feedback, which helps in the focused ablation of the target location. [ 3 ]
An artificial cardiac pacemaker, commonly referred to as simply a pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber (s) to contract and pump blood, [3] thus regulating the function of the electrical conduction ...
High-intensity focused ultrasound (HIFU), or MR-guided Focused Ultrasound Surgery is an incision-less therapeutic technique [1] that uses non-ionizing ultrasonic waves to heat or ablate tissue. HIFU can be used to increase the flow of blood or lymph or to destroy tissue, such as tumors, via thermal and mechanical mechanisms.
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
