چکیده

In this case study, we compare two methods for filtering external motion in time dependent volume data sets acquired from confocal microscopy. The pros and cons of a landmark based and a voxel based method are discussed. We show that filtering external motion is an essential first step for the visualization of confocal data.

A Simulation Study on Patient Setup Errors in External Beam Radiotherapy Using an Anthropomorphic 4D Phantom

Introduction Patient set-up optimization is required in radiotherapy to fill the accuracy gap between personalized treatment planning and uncertainties in the irradiation set-up. In this study, we aimed to develop a new method based on neural network to estimate patient geometrical setup using 4-dimensional (4D) XCAT anthropomorphic phantom. Materials and Methods To access 4D modeling of motion...

Affine correction without correspondence applied to 4D cellular motion in confocal microscopy

Nowadays, confocal microscopy is used for the quantitative 4D imaging of spatiotemporal processes in living cells. The transport of proteins in the cell during the cell cycle is presumably a process that plays a role in RNA transcription and DNA repair. Fluorescent labeling of such a protein reveals tens of moving spots in the cell. This motion, however, is superimposed on the translation and r...

Variations of the Normal Human Limbal Stem Cells Detected by In Vivo Confocal Microscopy

Background  To report normal variations of the limbal structures using in vivo laser scanning confocal microscopy. Methods: This was a retrospective study of fourteen eyes from 11 healthy individuals. Confocal imaging of cornea and limbus was performed using Heidelberg Retina Tomograph III Rostock Corneal Module. Results: The typical structure of the palisades of Vogt (POV) was detected ...

Advanced Motion Correction Methods in PET

With the arrival of increasingly higher resolution PET systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. In this work, we have reviewed advanced correction methods for the three cases of (i) unwanted patient motion, as well as motions due to (ii) cardiac and (iii) respiratory cycles. For the first type of ...

Dynamic MLC Tracking Using 4D Lung Tumor Motion Modelling and EPID Feedback

Background: Respiratory motion causes thoracic movement and reduces targeting accuracy in radiotherapy. Objective: This study proposes an approach to generate a model to track lung tumor motion by controlling dynamic multi-leaf collimators. Material and Methods: All slices which contained tumor were contoured in the 4D-CT images for...
