Towards automatic image registration of hyperpolarized He MRI and x-ray CT images of the lung
Introduction Initial work on He MRI to CT image registration [1] demonstrated the feasibility of fusing the images using control point rigid registration. More recently, an enhanced acquisition and registration protocol has been reported [2] that utilizes a new radiofrequency (RF) body coil, a 3D volume He MR acquisition sequence, and a multislice radiotherapy CT scanner. Although He MRI to CT ...
متن کاملMass preserving image registration for lung CT
This paper presents a mass preserving image registration algorithm for lung CT images. To account for the local change in lung tissue intensity during the breathing cycle, a tissue appearance model based on the principle of preservation of total lung mass is proposed. This model is incorporated into a standard image registration framework with a composition of a global affine and several free-f...

متن کاملHyperpolarized Helium MRI of Asthma
A distinguishing feature of asthmatic lungs is that, when provoked, the airways constrict heterogeneously [1]. However, the tools typically used to study ventilation heterogeneity in humans, i.e., measurement of lung mechanics [2] and multiple-breath inert gas washout [3], provide only global and implicit assessment of the functional impact of structural changes. Since airways constitute the pa...
متن کاملImage Registration for MRI
To register two images means to align them so that common features overlap and differences — for example, a tumor that has grown— are readily apparent. Being able to easily spot differences between two images is obviously very important in applications. This paper is an introduction to image registration as applied to medical imaging. We first define image registration, breaking the problem dow...
