The modification of the polyester track membranes by treatment in radiofrequency plasma generated by capacitive coupled parallel plate discharge in air and ammonia was studied.
The researchers found that with appropriate precautions, patients with pacemakers and defibrillators can have an MRI scan with very low risk of the device malfunctioning, moving, heating or causing abnormal heart rhythms due to the magnetic and radiofrequency energy generated by the test.
Radiofrequency-generating energy devices have been used clinically in musculoskeletal procedures to provide hemostasis and capsular shrinkage (thermal capsulorrhaphy).
Radiofrequency-generating energy devices have been used clinically in musculoskeletal procedures, such as chondroplasty [ 9, 13, 35, 39, 41], arthroscopic treatment of intraarticular tissues [ 1, 3, 14, 21, 26, 29, 31, 33, 43], meniscectomy [ 16, 25], and treatment of musculoskeletal tumors [ 8, 12, 23, 24, 27, 34, 37], to provide hemostasis and thermal capsulorrhaphy.
In a double-blind experiment, short-term wideband code division multiple access (WCDMA) radiofrequency electromagnetic fields generated no significant changes in subjective symptoms (fatigue, headache, dizziness, etc) in teenagers.
The radiofrequency generator was activated at each tumor site.
The instrument was connected to a commonly used radiofrequency generator.
New bipolar-cooled radiofrequency (BCRF) may generate larger controlled lesions without the same degree of risk to adjacent structures.
Our detection scheme is unique in that it uses a combination of a clinical field-strength (3 T) scanner, customized gradient and radiofrequency coils for generating high-resolution, high-SNR images and a pulse sequence (3DFIESTA) with high SNR efficiency and excellent sensitivity to susceptibility contrast created by iron deposits.
With ASL imaging, flow contrast is generated by using radiofrequency pulses tailored to label the protons electromagnetically in arterial blood.
