A concept is proposed to simplify patient positioning and scan planning to improve ease of use and workflow in MR. After patient preparation in front of the scanner the operator selects the anatomy of interest by a single push-button action. Subsequently, the patient table is moved automatically into the scanner, while real-time 3D isotropic low-resolution continuously moving table scout scanni...

Arthroscopy of the shoulder is a well-established and routine procedure. The role is expected to increase further with an ever-increasing list of indications reflecting the gratifying results. Intraoperative injuries of nerves related to positioning are known but, fortunately, rare with shoulder arthroscopy. Appropriate assessment of patient and careful positioning is paramount in prevention of...

Introduction: Modern radiotherapy treatment planning (RTTP) requires volumetric localisation of tumour and critical structures. 3dimensional computed tomography (CT) data is the preferred imaging modality in RTTP due to: spatial accuracy; electron density information; the speed of acquisition; the ability to image the patient in the treatment position and the visualisation of bony anatomy. Howe...

BACKGROUND Poor positioning of an endobronchial double lumen tube (DLT) could affect oxygenation during one lung ventilation (OLV). We set out to relate DLT position to hypoxaemia and DLT misplacement during OLV. METHODS We recruited 152 ASA physical status I-II patients about to have elective thoracic surgery. The trachea was intubated with a left-sided DLT. Tube position was assessed by fib...

Prone positioning has been used as a treatment option for patients with acute lung injury or acute respiratory distress syndrome (ARDS) since the early 1970s. Prone position and extended prone position ventilation have been shown to increase end-expiratory lung volume, alveolar recruitment, and oxygenation in patients with severe hypoxemic and acute respiratory failure. Prone positioning is not...

INTRODUCTION Intertrochanteric fractures of the femur are common fractures in the elderly, and management includes operative fixation after patient positioning on the fracture table. Patients with bilateral above-knee amputations are challenging in terms of positioning on the table. We describe a simple technique to overcome this special problem. CASE PRESENTATION A 75-year-old wheelchair-bou...

In proton therapy, robotic couch was used for patient positioning to achieve high precision in cancer treatment. However, no studies have focused on the real-time motion management system (MMS) couch. This study develop MMS and verify its feasibility. A set up with a couch, an NDI Vega optical tracking system, Special Measurement Tool (SMT) developed software. Leica laser tracker adopted accura...

Accurate multileaf collimator (MLC) leaf positioning plays an essential role in the effective implementation of intensity modulated radiation therapy (IMRT). This work evaluates the sensitivity of current patient-specific IMRT quality assurance (QA) procedures to minor MLC leaf positioning errors. Random errors of up to 2 mm and systematic errors of +/-1 mm and +/-2 mm in MLC leaf positions wer...

OBJECTIVE Interest in flaps based on the subscapular vascular system has decreased because of the need for intraoperative patient repositioning and the inability to employ a simultaneous 2-team approach. The aims of this study are to review our experience using dorsal decubitus patient positioning for subscapular-based flap harvest and to demonstrate the effectiveness and safety of this approac...
