Microwave 245ghz skin tightening evidence for Thigh fat

Abstract summary (English) BACKGROUND: Hepatocellular carcinoma (HCC) is a primary tumor of the liver with poor prognosis. For early stage HCC, treatment options include surgical resection, liver transplantation, and percutaneous ablation. Percutaneous ablative techniques (radiofrequency and microwave techniques) emerged as best therapeutic options for nonsurgical patients.

Journal Article, Randomized Controlled Trial

Abstract summary (English) BACKGROUND: The body contour market has grown steadily over the last years, due to the persistent demand for non-invasive treatments for localized fat adiposities, cellulite, and skin laxity. MATERIALS AND METHODS: The purpose of this observational study was to evaluate the efficacy and safety of a new device delivering microwaves (MWs) energy for unwanted fat and cellulite reduction after a full cycle of treatments...

Observational Study, Journal Article, Retracted Publication

Abstract summary (English) The dielectric properties of cod, perch, salmon, chicken breast, chicken thigh and beef were measured at 15 to 65 degrees C at 2450 MHz. The samples covered a moisture range of 68.9-81.2% and ash range of 0.96-1.20%. Equations were developed as a function of temperature, moisture, and ash, and compared to literature equations.

Comparative Study, Evaluation Study, Journal Article, Validation Study

Abstract summary (English) This study presents a comparative evaluation of the control of heating and thermal coagulation with microwave (MW) and ultrasound (US) interstitial applicators. Helical coil MW antennas (17 mm and 25 mm length radiating antennae) were tested using an external implant catheter (2.2 mm o.d.) with water-cooling. US applicators with tubular transducers (2.2 and 2.5 mm o.d., 10 mm length, single-element and 3-element)...

Abstract summary (English) Steady-state temperature distributions induced by commercial radiofrequency localized current field (RF-LCF) and microwave (MW) interstitial heating systems were compared in dog thigh muscle in vivo using repeated 15-min heating experiments in the same implant site. Control experiments consisting of up to nine successive, identical heat trials with either modality verified that induced temperature distributions...

Abstract summary (English) To adequately plan and administer localized hyperthermia with interstitial microwave antennas, the thermal distribution patterns generated by such antennas must be characterized. This study evaluated the performance of single node 915 MHz antennas operating either alone or as a 2 cm square array of four parallel antennas using both muscle-equivalent phantoms and canine thigh muscle. Two types of measurements were...

Abstract summary (English) An 84-year-old woman had a squamous cell carcinoma on her left thigh. Before operation, half of the tumor mass was irradiated with a microwave at 43 degrees C for an hour. After the hyperthermia, the tumor mass was removed, and the DNA instability was investigated by microfluorocytometric measurement of the cells stained with pararosaniline-Feulgen after hydrolysis with 2N HCl at 30 degrees C.

Abstract summary (English) OBJECTIVE: Microwave imaging has been investigated for medical applications such as stroke and breast imaging. Current systems typically rely on bench-top equipment to scan at a variety of antenna positions. For dynamic imaging of moving structures, such as the cardiovascular system, much higher imaging speeds are required than what has thus far been reported.

Abstract summary (English) OBJECTIVE: To demonstrate the feasibility of percutaneous microwave ablation in desmoid fibromatosis with respect to tumor volume control and improvement in the quality of life. MATERIALS AND METHODS: Twelve microwave ablations were performed in 9 patients with a histological diagnosis of desmoid fibromatosis between January 2010 and January 2019. The study population included 6 female and 3 male, with an age range...

Journal Article

Abstract summary (English) This paper presents the latest development of the hybrid microwave-optical thermoregulation monitor for the muscle. It is capable of warming the muscle and measuring the subsequent blood volume changes, using a novel microwave applicator with integrated optical probes. The challenge is to measure the thermoregulation response in deep tissue while minimizing any effect from the skin layer.
