... robotic assisted MIS. The information is collected from two force sensor/pressure matrices and processed with a new algorithm and graphically rendered. Consequently, the surgeon can determine the presence, location, and the size of any hidden superficial tumor/artery by grasping the target tissue...

... interventions. In fact, minimal invasive neurosurgery, which can be adopted for aspiration of intracranial hematomas, catheter insertion, tumor biopsies, and deep brain stimulation, requires a precise individuation of the target point into the brain and a system that may enhance the accuracy of the surgical...

... cells, a real-time infrared (IR) thermal image-based tumor tracking system for breast cancer radiotherapy is developed in this research. In the system, the real-time feedback of breast tumor locations consists of the images taken by an IR thermal camera system. A serial six-degree-of-freedom manipulator...

... characterization. In comparison with dynamic method of MR elastography, this quasi-static method is relatively simple to implement since no motion sensitive gradient or gradient synchronization is required. A limitation of indentation method is the difficulty to obtain significant deformation of tumor inside...

... table. In the case of biopsy, for example, this would allow the surgeon to guide the needle tip to a tumor though opaque tissue. It has been well established that for soft tissues, image registration can be performed by aligning the preoperative image with a cloud of points that describe the surface...

...D. M. Smeenge; M. C. Frost Nitric Oxide (NO) is small, free radical gas that has been shown to have a wide variety of physiological functions, including the ability to hinder tumor angiogenesis at high, but non lethal, concentrations. Previous work suggests that if NO could be effectively delivered...

.... Thermochemical ablation is a potential technique for percutaneous probe-based tumor therapy. It involves simultaneous intratumoral delivery of multiple reagents resulting in thermal energy released by an exothermic reaction to ablate tumor tissue with concurrent generation of a hyperosmolar byproduct that could...

...-tumorally. Injecting TNF- α solution into the center of the tumor comprised the intra-tumoral approach. For peri-tumoral injection, TNF- α solution was injected at each one of eight evenly distributed points spanning the circumference of the tumor base. CYT-6091 was administered by i.v. injection only...

... vs. 0.13 ± 0.05 cm 3 , p = 0.01 ). Excessive tumor growth into the ablation lesion at day 7 following cryoablation prevented accurate measurements in these groups; however, a significant decrease in the rate of peritoneal carcinomatosis (metastases) was obtained in the cryo plus CYT-6091 group...

... types of cancer cells, including colon cancer, and plays an important role in tumor growth and metastasis. Thus, the ability to target the integrin α 5 β 1 using an appropriate drug delivery nano-vector can signficantly help in inhibiting tumor growth and reducing tumor metastasis.
