We propose a method to automatically tune a patient-based virtual environment training simulator for abdominal needle insertion. The key attributes to be customized in our framework are the elasticity of soft-tissues and the respiratory model parameters. The estimation is based on two 3D Computed Tomography (CT) scans of the same patient at two different time steps. Results are presented on four patients and show that our new method leads to better results than our previous studies with manually tuned parameters.

Chhikara A, McGregor AH, Hadjilucas L, et al., 2010, Quantitative assessment of the motion of the lumbar spine and pelvis with wearable inertial sensors, Pages: 9-15
Chronic Low Back Pain (CLBP) is a leading cause of disability with significant economic costs and severe psychological and social consequences. LBP patients also have the tendency to change the movement of the back and hold the pelvis rigid. Currently, the clinical assessment of a LBP patient is undertaken at a single point in time during clinic visits rather than through continuous monitoring. To monitor motion of the lumbar spine and pelvis, we have developed a wearable prototype sensor based on inertial sensor technology combined with the Body Sensor Network (BSN) platform. The device enables quantitative assessment of motion, especially the proportion of pelvic to lumbar movement. The developed device has been tested in a pilot study with healthy volunteers for a range of movements and results validated by optical tracking. This paper presents our approach and exemplifies the quantitative assessment of the lateral flexion movement. The next stage of the project will involve testing with patients. © 2010 IEEE.

INTRODUCTION: Current arc-lamp illumination systems have a number of technical and ergonomic limitations. White light-emitting diodes (LEDs) are energy-efficient solid-state lighting devices which are small, durable and inexpensive. Their use as an alternative to arc-lamp light sources in minimal access surgery has not been explored. This study aims to develop an LED-based endo-illuminator and to determine its lighting characteristics for use in minimal access surgery. METHODS: We developed an LED endo-illuminator using a white LED mounted at the tip of a steel rod. Offline image analysis was carried out to compare the illuminated field using the LED endo-illuminator or an arc-lamp based endoscope in terms of uniformity, shadow sharpness and overall image intensity. Direct radiometric power measurements in light intensity and stability were obtained. Visual perception of fine details at the peripheral endoscopic field was assessed by 13 subjects using the different illumination systems. RESULTS: Illumination from the LED endo-illuminator was more uniform compared to illumination from an arc-lamp source, especially at the closer distance of 4 cm (0.0006 versus 0.0028 arbitrary units--lower value indicates more uniform illumination). The shadows were also sharper (edge widths of 16 versus 44 pixels for the first edge and 15 versus 61 pixels for the second edge). The overall mean image intensity was higher (127 versus 100 arbitrary units) when using the autoshutter mode despite the lower direct radiometric power, about one tenth of the arc-lamp endoscopic system. The illumination was also more stable with less flickering (0.02% versus 5% of total power in non-DC components). Higher median scores on visual perception was also obtained (237 versus 157, p < 0.001). CONCLUSION: The LED endo-illuminator provides more uniform illumination with sharper shadows, less flickering and better illumination for visual perception than the arc-lamp-based system currently used.
