An improved Virtual Torso phantom
INTRODUCTION Lung counting has many sources of uncertainty that can impact on the activity estimate such as different deposition patterns of radioactivity in the lung, rib size and placement, chest wall composition and profile, effect of detector size and thickness. For example, if a lung counter is calibrated using a lung set that has the activity homogeneously distributed throughout the tissu...
متن کاملSpectre: An Improved Phantom Edge Finder
Both edge finders use the topological sum to remove noise from second difference responses, so that zero-crossings in these responses represent reliable boundaries. Spectre applies the same techniques to a combination of first and third differences, producing a new map that reliably distinguishes real boundaries from spurious boundaries appearing in staircase intensity patterns. Similar process...
متن کاملAn Immersive Virtual Environment for Phantom Limb Pain Rehabilitation
Phantom Limb Pain is a debilitating condition that affects a significant percentage of patients after loss of an arm or leg. These patients experience chronic pain and other unpleasant sensations in the missing limb, and the pain resists treatment. Previous research has demonstrated that pain levels can be reduced in some patients when they are immersed in a virtual environment that presents a ...
متن کاملImplementing Virtual Stairs on Treadmills using Torso Force Feedback
Abstruct-This paper describes the simulation of stairs on a treadmill style locomotion interface using torso force feedback. The active mechanical tether of the Sarcos Treadport locomotion interface applies a specialized force profile to simulate the forces of stair walking. The biomechanics of subjects walking on real stairs versus walking under the specialized force prolile were compared. It ...
متن کاملVirtual arm for the phantom pain therapy
Phantom limb pain appears where an amputated limb used to be and is often excruciating and almost impossible to treat. Recently, two experiments on hand amputees in the neuroscience area have shown that if a patient has the visual illusion of his phantom hand in a way that he is able to move it, the phantom pain can decrease. We propose a new augmented reality system aiming to experiment this i...
