We have undertaken electron micrographic reconstruction of the Caenorhabditis elegans hermaphrodite uterus and determined the correspondence between cells defined by their lineage history and differentiated cell types. In this organ, many cells do not move during morphogenesis and the cell lineage may function to put cells where they are needed. Differentiated uterine cell types include the tor...

Objective: A novel multifocal collimator, IQ-SPECT (Siemens) consists of cardio-centric and 3D iterative SPECT reconstruction and makes it possible to perform MPI scans in a short time. The aims are to delineate the normal uptake in thallium-201 (Tl) SPECT in each acquisition method and to compare the distribution between new and conventional protocol, especially in patients with normal imaging...

In this work, an adaptive image compression algorithm is proposed based on the prediction of AC coefficients in Discrete Cosine Transform (DCT) block during reconstruction of image. In the prediction phase, DC values of the nearest neighbour DCT blocks is utilized to predict the AC coefficients of centre block. Surrounding DC values of a DCT blocks are adaptively weighed for AC coefficients pre...

A direct force on the superior aspect of the shoulder may cause acromioclavicular (AC) dislocation or separation. Severe dislocations can lead to chronic impairment, especially in the athlete and high-demand manual laborer. The dislocation is classified according to Rockwood. Types I and II are treated nonoperatively, while types IV, V and VI are generally treated operatively. Controversy exist...

Rigshospitalet, University of Copenhagen, Denmark For a quantitative analysis in positron emission tomography (PET) or single-photon emission computed tomography (SPECT), attenuation correction (AC) is mandatory. CTscans or transmission scans are common tools for determination of the attenuation μ-map, but in the case of a PET/MR hybrid system it is difficult to associate one of these scans. Ma...

Abstract Currently, patients use the Internet for health information relating to surgery. The aim of this study is assess readability and quality online acromioclavicular joint reconstruction. We hypothesise that will be poor too difficult read average patient. top 50 results from Google, Bing, Yahoo (MeSH “acromioclavicular reconstruction”, “ac reconstruction”) were used analysis. Readability ...

BACKGROUND Although numerous suture-button fixation techniques for acromioclavicular (AC) joint reconstruction have been validated with biomechanical testing in the superior direction, clinical reports continue to demonstrate high rates of construct slippage and breakage. PURPOSE To compare the stability of a novel closed-loop double Endobutton construct with a commercially available cortical...

German Cancer Research Center (DKFZ), Heidelberg, Germany Accurate quantification of the activity distribution in positron emission tomography (PET) mandates attenuation correction (AC). Unlike in PET/CT, AC in PET/MR is, however, challenging, since information about the attenuation properties of the patient tissue distribution is not available directly. Standard MR-based AC (MRAC) does not acc...

Image compression techniques are widely used in 2D and 3D image and video sequences. There are many types of compression techniques and among the most popular are JPEG and JPEG2000. In this research, we introduce a new compression method based on applying a two level Discrete Wavelet Transform (DWT) and a two level Discrete Cosine Transform (DCT) in connection with novel compression steps for h...
