This report describes our initial in vitro results with roboticallyassisted strain imaging for intraoperative monitoring of hepatic tumor thermal ablation. First, we demonstrate a strong correlation between thermal ablation of liver tissue and changes in elastic properties. Second, we present an experimental environment to provide controlled robotically-assisted compression of liver tissue with...

Uterine fibroids are benign solid tumors that are present in the majority of women. While often asymptomatic, fibroids can result in abnormal uterine bleeding, pelvic pressure, pain, subfertility, dyspareunia and other symptoms. Submucous and intramural fibroids are most associated with heavy menstrual bleeding; subserosal fibroids are more often innocuous unless sufficiently large so as to con...

For application in UV-material processing and UV-thin-film optics, the thermal contribution to damage and ablation phenomena will be investigated utilizing time resolved photothermal probe beam deflection (MIRAGE) technique. The potentiality of this method for the determination of both the sub-damage range and the Onset of damage, as well as the ablation threshold by using the thermal branch of...

Objective: To evaluate therapy effects and capability to preserve adjacent tissues of bilateral focal prostate ablation using Nd: YAG laser a canine model. Methods: 24 male Beagle dogs aged 3.9-7.4 years and weighting 9.4-12.1 kg were used in this study. The dogs underwent single focal Nd: YAG ablation. Applied the reasonable prostatic ablation parameters screened in the study and set different...

Background Image-guided thermal ablation can be used for the treatment of medically inoperable primary and metastatic lung cancer. These techniques are based on the heating up or freezing (cryoablation) of a volume of tissue around a percutaneous applicator that induces necrosis of the tumor. Method The English-language literature concerning thermal ablation of the lung was reviewed. Radiofrequ...

PURPOSE To identify changes in plasma cytokine levels after image-guided thermal ablation of human tumors and to identify the factors that independently predict changes in plasma cytokine levels. MATERIALS AND METHODS Whole-blood samples were collected from 36 patients at three time points: before ablation, after ablation (within 48 hours), and at follow-up (1-5 weeks after ablation). Plasma ...

Thermal ablation is an interventional technique that promises to enable percutaneous treatment of many cancers and other disorders throughout the human body. Acoustic ablation offers the possibility of steering thermal energy electronically [1], and is known to be MRI compatible, and thus amenable to real-time thermal dose monitoring through MR thermometry. We propose a pneumatically actuated r...

Therapeutic irreversible electroporation (IRE) is a relatively new technique for targeted tumor ablation. Needle electrodes are placed into or around the targeted region to deliver a series of brief electric pulses that disrupt cell membrane integrity, killing cells in a non-thermal manner that does not affect the extracellular matrix or sensitive structures such as major vasculature and bile d...
