Patient positioning is crucial to accurate dose delivery during radiation therapy to ensure the proper localization of dose to the target tumor volume. In patient positioning for stereotactic radiation therapy treatment, classical image registration methods are computationally costly and imprecise. We developed an automatic, fast, and robust 2D-3D registration method to improve accuracy and spe...

Patient positioning in theatre pertains to how a patient is transferred and positioned for a specific procedure. Patient safety is a central focus of care within the NHS and every healthcare practitioner must ensure that patients are protected from harm where possible. Mal-positioning of the patient has important implications in terms of associated problems of pressure sores, nerve compressions...

A surface imaging system, Catalyst (C-Rad), was compared with laser-based positioning and daily mega voltage computed tomography (MVCT) setup for breast patients with nodal involvement treated by helical TomoTherapy. Catalyst-based positioning performed better than laser-based positioning. The respective modalities resulted in a standard deviation (SD), 68% confidence interval (CI) of positioni...

PURPOSE This study was performed to determine the relative frequency of positioning errors, to identify those errors directly responsible for diagnostically inadequate images, and to assess the quality of panoramic radiographs in a sample of records collected from a dental college. MATERIALS AND METHODS This study consisted of 1,782 panoramic radiographs obtained from the Department of Oral a...

The air embolism in this case was likely to have been caused by positioning the patient in a prone position, which was associated with the lesion to be biopsied being at a maximum height over the left atrium. Due to the resulting negative pressure, air entered through a fistula that formed between the airspace and the pulmonary vein. The air could have been trapped in the left atrium by positio...

introduction : the dynamic interaction between mother and infant is one of the indicative factors of infants’ social and emotional development especially in stressful situations as cognitive evaluating. methods: an experimental study was completed in 2010 in tehran on a total of 40 infants (18 boys and 22girls) forming two alternative groups and varying in age of infancy (4, 6, 8, 10 and 12 mon...

Patient positioning is an integral part of perioperative care and yet it is an area of patient care which can easily be compromised as staff try to accommodate surgeons and work through busy operating lists. Inadequate padding and incorrect positioning can cause serious and long term injury and disability, and can result in litigation against perioperative nurses and ODPs.
