It may be argued that seizing large quantities of heroin being imported into the country should decrease its supply and hence increase its price, resulting in a reduction in the quantity of the drug being purchased or consumed. To date, however, there has been no empirical evidence that heroin seizures in Australia have any effect on the price of heroin at(More)
A prospective study of the sagittal plane motion of the cervical spine, stabilized with a halo-vest was performed in 31 consecutive patients with unstable cervical spine injuries. Motion was measured in lateral radiograms taken with the patient in different positions and while performing various exercises. The extreme angle in extension and flexion in each(More)
Haptic technology enables us to incorporate the sense of touch into computer applications, providing an additional input/ output channel. The purpose of this study was to examine if haptic feedback can help physicians and other practitioners to interact with medical imaging and treatment planning systems. A haptic application for outlining target areas (a(More)
This present paper presents an analytical description and numerical simulations of the influence of macroscopic intercell dose variations and intercell sensitivity variations on the probability of controlling the tumour. Computer simulations of tumour control probability accounting for heterogeneity in dose and radiation sensitivity were performed. An(More)
Seven different radiobiological dose-response models have been compared with regard to their ability to describe experimental data. The first four models, namely the critical volume, the relative seriality, the inverse tumor and the critical element models are mainly based on cell survival biology. The other three models: the Lyman (Gaussian distribution),(More)
BACKGROUND AND PURPOSE Health-related quality of life (HRQoL) instruments have been of increasing interest for evaluation of medical treatments over the past 10-15 years. In this prospective, long-term follow-up study we investigated the influence of preoperative factors and the change in HRQoL over time after lumbar disc herniation surgery. METHODS 117(More)
OBJECT Radiation treatment of large arteriovenous malformations (AVMs) remains difficult and not very effective, even though seemingly promising methods such as staged volume treatments have been proposed by some radiation treatment centers. In symptomatic patients harboring large intracranial AVMs not amenable to embolization or resection, single-session(More)
Radiobiological models for estimating normal tissue complication probability (NTCP) are increasingly used in order to quantify or optimize the clinical outcome of radiation therapy. A good NTCP model should fulfill at least the following two requirements: (a) it should predict the sigmoid shape of the corresponding dose-response curve and (b) it should(More)

3 ABSTRACT Biological treatment optimization aim at improving radiation therapy by accounting for the radiobiological tumour and normal tissues response properties when optimizing the dose delivery. Generally traditional methods, using only dosimetrical measures, disregard the non-linear radiation response of different tumours and normal tissues. The(More)
