Hippocampal volumes of subjects with a history major depressive episodes but currently in remission and no known medical comorbidity were compared to matched normal controls by using volumetric magnetic resonance images. Subjects depression had significantly smaller left right hippocampal differences total cerebral volumes. The degree volume reduction correlated duration depression. In addition, large (diameter > or = 4.5 mm)-hippocampal low signal foci (LSF) found within the hippocampus,...
Despite major advances in x-ray sources, detector arrays, gantry mechanical design and especially computer performance, one component of computed tomography (CT) scanners has remained virtually constant for the past 25 years—the reconstruction algorithm. Fundamental have been made solution inverse problems, tomographic reconstruction, but these works not translated into clinical related practice. The reasons are obvious seldom discussed. This review seeks to examine this discrepancy provides...
Three dimensional reconstruction images of bony and soft tissue surfaces have improved understanding complex facial deformities. Applied to CT studies craniofacial abnormalities, this method has delineated abnormal morphology, facilitated surgical planning, quantitative postoperative evaluation. Advanced computer-aided aircraft design techniques were adapted applied procedure-planning evaluation using surface contours obtained from scans.
Iterative deblurring methods using the expectation maximization (EM) formulation and algebraic reconstruction technique (ART), respectively, are adapted for metal artifact reduction in medical computed tomography (CT). In experiments with synthetic noise-free additive noisy projection data of dental phantoms, it is found that both simultaneous iterative algorithms produce superior image quality as compared to filtered backprojection after linearly fitting gaps. Furthermore, EM-type algorithm...
Context.Optical long-baseline interferometry is moving a crucial step forward with the advent of general-user scientific instruments that equip large aperture and hectometric baseline facilities, such as Very Large Telescope Interferometer (VLTI).
In this paper, we present a semi-supervised deep learning approach to accurately recover high-resolution (HR) CT images from low-resolution (LR) counterparts. Specifically, with the generative adversarial network (GAN) as building block, enforce cycle-consistency in terms of Wasserstein distance establish nonlinear end-to-end mapping noisy LR input denoised and deblurred HR outputs. We also include joint constraints loss function facilitate structural preservation. process, incorporate...
Objectives In mouse models of pancreatic cancer, IPI-926, an oral Hedgehog inhibitor, increases chemotherapy delivery by depleting tumor-associated stroma. This multicenter phase Ib study evaluated IPI-926 in combination with FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan, oxaliplatin) patients advanced cancer. Methods Patients were treated once-daily plus FOLFIRINOX. A 3 + dose escalation design was used, cohort expansion at the maximum tolerated dose. subset underwent perfusion...

Aims.In this paper, we present an innovative data reduction method for single-mode interferometry. It has been specifically developed the AMBER instrument, three-beam combiner of Very Large Telescope Interferometer, but it can be derived any interferometer.
Magnetic resonance (MR) imaging systems produce spatial distribution estimates of proton density, relaxation time, and flow, in a two dimensional matrix form that is analogous to the image data obtained from multispectral satellites. Advanced NASA satellite processing offers sophisticated analysis MR images. Spin echo inversion recovery pulse sequence images were entered digital format compatible with accurately registered pixel by pixel. Signatures each tissue class automatically determined...
To test automated three-dimensional magnetic resonance (MR) imaging morphometry of the human hippocampus, to determine potential gain in precision compared with conventional manual morphometry.A canonical MR image atlas was used as a deformable template and automatically matched images 10 individuals (five healthy five schizophrenic subjects). A subvolume containing hippocampus defined by using 16 landmarks that constrained search for hippocampal boundaries. Transformation performed global...

A noninvasive computer imaging technique allows three-dimensional images of fossil skulls to be generated from two-dimensional serial computerized tomographic scan data. The programs can "dissect" the skull in different planes by making portions it and any obstructing matrix transparent order reveal intracranial morphology. image is geometrically precise so that linear distances, angles, areas, volumes, evaluations symmetry determined.
The understanding of complex craniofacial deformities has been aided by high resolution computed tomography. Nonetheless, the planar format limits spatial comprehension. Reconstruction fully three-dimensional bony and soft tissue surfaces from CT scans accomplished a level slicing edge detector coupled to hidden surface processor without perspective depth transformation. This method clarified aberrant anatomy, facilitated surgical planning improved quantitative postoperative evaluation in...
