.... demyelinization, sclerosis and eventually necrosis; T1 weighted images show necrosis, and T1 images with gadolinium injections show the active demyelinizing areas [5, 6] Some automatic methods make it possible to find lesions based one temporal exam (e.g. 7, 8] Moreover Guttmman et al. [9] show that MR scans make it also possible to do the follow up of a patient with multiple sclerosis. In this case a time series of 3D images of a patient is usually acquired from the same modality and with a specific protocol to have similar properties: field of view, image size, voxel size, etc. ....

....This is implemented with a parallel unity gain filtering step [Wells, 1986] that costs only two multiplies per voxel per axis, independent of filter length. We have applied this technique to the segmentation of MR scans of patients with schizophrenia [Iosifescu, 1997] multiple sclerosis [Kikinis, 1997], and normal volunteers [Morocz,1997] 4.4 Linear Registration Linear registration algorithms typically are used for the purpose of aligning several data sets of the same subject that contain complementary information (e.g. a CT and an MRI scan) see Figure 2. Another application is the initial ....

....due to the dioeerence in contrast. Other artifacts such as chemical shift or susceptibility eoeects may also account for the observed bias as they inAEuence the detection of extremal points. Indeed, the two echoes are acquired with different receiver RF bandwidth to improve the signal noise ratio [6]. Therefore, the chemical shift and the susceptibility eoeect are dioeerent in the two echoes. In a future work, we plan to correlate the biases with diverse quantities in the images in order to understand their origin. Ultimately, we would like to predict the biases in each acquisition before ....

....estimation of the geometric transformation from matched features. The quanti cation of the registration quality is also an important problem as most measurements are done after registration. For instance, registration errors can have a strong inAEuence on the quanti cation of the lesion evolution [3]. Knowing the uncertainty of the transformation might even be vital in image guided surgery when it comes to operate close to important anatomical structures. Most existing methods for computing 3D rigid motion deal with sets of matched points and minimize the sum of square distances after ....
