Purpose: Continuous tumor position measurement coupled with a tumor tracking system would result in a highly accurate radiation therapy system. Previous internal position monitoring systems have been limited by fluoroscopic radiation dose and low delivery efficiency. We aimed to incorporate a continuous, electromagnetic, threedimensional position tracking system (Calypso 4D Localization System)...

This is a case report on stereotaxic (Stereotactic Body Radiotherapy-SBRT) for lung cancer located in the left lower lobe (Segment 6, S6). There have been no reports on marked displacement of the peripheral lung cancer during radiotherapy. A pulmonary nodule was discovered on computed tomography (CT) conducted for a persistent cough in an 87-year-old male. According to diagnostic imaging, this ...

Background: Aim of this study is to evaluate the accuracy of the gated volumetric modulated arc therapy (VMAT/RapidArc) using 2D planar dosimetry, DynaLog files and COMPASS 3D dosimetry system. Materials and Methods: Pre-treatment quality assurance of 10 gated VMAT plans was verified using 2D array and COMPASS 3D dosimetry system. Advantage of COMPASS over 2D planar is that it provides the clin...

OBJECTIVE To compare the pelvic floor function of primiparous women to women after a second delivery regarding symptoms of urinary and anal incontinence, anal sphincter ruptures and bladder-neck mobility. METHODS A questionnaire evaluating symptoms of urinary and anal incontinence was used in nulliparous women before and 27 months after childbirth. Furthermore these symptoms were correlated w...

The last step of a successful pregnancy is the safe delivery of the fetus. An important question is if the delivery should vaginal or operative. In addition to the use of conventional antenatal ultrasound, the use of intrapartum ultrasound to evaluate fetal head station, position, cervical ripening, and placental separation is promising. This review evaluates and summarizes the usefulness of in...

OBJECTIVE We performed a systematic review to determine whether sonographic assessment of occipital position of the fetal head can contribute to the prediction of the mode of delivery. METHODS We performed a systematic literature search of electronic databases from inception to May 2011. Two reviewers independently extracted data from the included studies. We used a bivariate model to estimat...

During the past 10 years there has been an increase in the rate of cesarean sections, and at the same time interest has increased regarding the effects of anesthesia on mother, fetus and newborn. In spite of improved procedures in anesthetics, in some cases newborns are in a depressed state after delivery by cesarean section. According to CRAWFORD [2] this is caused by drugs or biochemical fact...

AIMS Transcatheter aortic valve implantation (TAVI) is an emerging field with technological challenges. One major challenge is to minimise delivery catheter size to reduce vascular trauma, while maintaining features such as repositionability and retrievability. This study was designed as proof of concept of FOLDAVALVE, using a short-term ovine model. METHODS AND RESULTS FOLDAVALVE is a fully ...

BACKGROUND Childbirth medicalization has reduced the parturient's opportunity to labour and deliver in a spontaneous position, constricting her to assume the recumbent one. The aim of the study was to compare recumbent and alternative positions in terms of labour process, type of delivery, neonatal wellbeing, and intrapartum fetal head rotation. METHODS We conducted an observational cohort st...
