An image overlay system is presented to assist needle placement in conventional CT scanners. The device consists of a flat LCD display and a half mirror and is mounted on the gantry. Looking at the patient through the mirror, the CT image appears to be floating inside the patient with correct size and position, thereby providing the physician with two-dimensional “X-ray vision” to guide needle ...

Several validated sham acupuncture devices have recently become available. While some debate exists on whether such needles are the best placebo control for an RCT of acupuncture, practical advice based on research experience is missing from the literature. This paper shares our concrete experience using the most commonly used such sham needle (the ‘Streitberger needle’ and its paired verum nee...

AIM To compare the flow rates of readily available intravenous infusion devices and to compare the effect of the addition of pressure or a needle-free intravenous connector device. METHODS Several intravenous devices with different characteristics had their flow rates determined under a standard set of conditions. The flow rates were then measured with the addition of a pressure bag to the sy...

A rapid on-site air sampling technique was developed with a miniaturized needle-type sample preparation device for a systematic evaluation of the indoor air environments in school facilities. With the in-needle extraction device packed with a polymer particle of divinylbenzene and activated carbon particles, various types of volatile organic compounds (VOCs) were successfully extracted. For eva...

Needle biopsy of small or nonpalpable breast lesions has a high nondiagnostic sampling rate even when needle position is guided by stereotaxis or ultrasound. We assess the feasibility of using a near-infrared fiber optic probe and computer-aided detection for the microscopic guidance of needle breast biopsy procedures. Specimens from nine consented patients undergoing breast-conserving surgery ...

The aim of this study was to compare the therapeutic effects of rhGH administered either by subcutaneous needle-injection (pens) or subcutaneous needle-free jet-injection (VISION(®)). Furthermore, a survey was carried out after using VISION(®) for 12 mo. A needle-free injection group consisting of 18 subjects (11 males and 7 females, mean age 5.87 ± 2.05 yr at the start of hGH therapy) who have...

Proper analytical physically based model to predict fluctuations in the threshold voltage due to a single interface trap at a random location along the channel in a typical sub-50 nm MOSFET is of utmost significance. This research summary compares the efficacy of the existing analytical model based on dopant number fluctuation estimation in the channel of a MOSFET when compared to 3D Ensemble M...

The clinical safety, use and pharmacokinetics of a new needle-free device for delivery of growth hormone (GH) were compared with those of conventional needle injection devices. In an open-label, randomized, 4-period crossover study, 18 healthy adults received single subcutaneous injections of Genotropin administered by the Genotropin ZipTip needle-free device and by conventional injection. Bioe...
