The increasing need for robustness, reliability and flexibility of relative navigation systems imposed by the current and future autonomous formation flying missions, calls for the implementation of solutions using an alternative approach to single-sensor systems. These schemes possess different levels of availability, mainly driven by sensor failure and mission orbit profiles. The data obtaine...

Although many head and neck surgeons agree that complete surgical excision is the treatment of choice for lymphatic malformation, the infiltrating nature of microcystic lymphatic malformations and the involvement of vital structures of the head and neck make total removal nearly impossible in most cases. Recently radiofrequency ablation was introduced for the treatment of microcystic lymphatic ...

Radiofrequency radiation dosimetry describes how this radiation is being absorbed in the body. The basic units of measuring the radiofrequency exposure are the electric E (V/m), magnetic B (A/m) field strength, the power density S (W/m 2 ), and the Specific Absorption Rate (SAR) (W/kg). Many studies have made use of different types of instruments to assess the level of radiofrequency radiation ...

Ultrabroad-bandwidth radiofrequency pulses offer significant applications potential, such as increased data transmission rate and multipath tolerance in wireless communications. Such ultrabroad-bandwidth pulses are inherently difficult to generate with chip-based electronics due to limits in digital-to-analog converter technology and high timing jitter. Photonic means of radiofrequency waveform...

background: drug resistance is widely believed to be an increasingly serious threat to global public health. we have previously reported that short term exposure of microorganisms to diagnostic ultrasound waves could significantly alter their sensitivity to antibiotics. in our previous studies, klebsiella pneumoniae showed major differences in the sensitivity to antibiotics in exposed and non-e...

Although surgical resection remains the best option as potentially curative therapy for hepatocellular carcinoma, radiofrequency thermal ablation has begun to receive much attention as an effective minimally invasive technique for the local control of unresectable malignant hepatic tumors. Most recent radiofrequency devices equipped with a powerful generator and larger needle electrode permit l...

According to a 2012 American Medical Association publication (Clinical Examples in Radiology, Vol. 8, Issue 3; Summer 2012), “microwave is part of the radiofrequency spectrum, and simply uses a different part of the radiofrequency spectrum to develop heat energy to destroy abnormal tissue.” Therefore, they instruct that microwave ablation should be reported using the CPT codes for radiofrequenc...

We review here the latest studies on efficacy of and techniques employed in radiofrequency neurotomy of the sacroiliac joint. Radiofrequency neurotomy has been shown to have limited evidence in treating sacroiliac joint syndrome. Variability in results has been attributed to individual nerve patterns, improper diagnosis, and selection of patients, as well as variability in the procedure itself....

BACKGROUND Catheter-based renal denervation (RDN) is a promising approach to treat hypertension, but innervation patterns limit the response to endovascular RDN and the post-procedural renal artery narrowing or stenosis questions the endovascular ablation strategy. This study was performed to investigate the anti-hypertensive and target organ protective effects of perivascular RDN in spontaneou...
