Quality of microcalcification segmentation in mammograms by clustering algorithms

Abstract

A scheme for quantum-state tomography is presented that can be performed for polarized light with an arbitrary photon-number distribution. The proposed method fills the gap between existing polarization-tomography schemes for single-photon states and for optical fields with very large photon numbers. It consists of an optical homodyne setup triggered by the outcome of a single-photon counting module. The configuration space of polarization is parametrized by Euler angles and by an additional interference parameter, whose assessment requires conditional homodyne measurements.

Figuera, L.E.",,"2014",,"Pure 9p trisomy derived from a terminal balanced unrecipwcal translocation: The 9p trisomy is a relatively frequent disorder, while pure 9p trisomies are less frequent and usually derived from 9;22 translocations, duplications or 9p extra chromosomes. Here we report a patient with pure trisomy 9p derived from a terminal balanced unreciprocal translocation. The patient derived to the genetic service by psychomotor delay, presented at 2 years and 11 months: Short stature, open anterior fontanelle, dysplastic ears, facial dysmorphisms, long and broad first toes with hypoplastic nails, central nervous system and skeletal alterations. The patient karyotype was: 46,XY,dcr(10)t(9;l0) (pl3.1;qter)mat while the mother karyotype was: 46,XX,t(9;10)(pl3.1;qter). The presence of the subtelomeric region of lOq showed by FISH as well as the duplication of 9p subtelomere was further confirmed with multiplex ligation dependent probe amplification (MLPA) for the subtelomeric region of all chromosomes. The mechanism of formation seems to be due to a telomere break in lOq leading to loss of tclomeric functions, permitting the 9p fusion; this has been supported with molecular probes showing telomere shortening in interstitial telomeric repeats, which are unable to prevent chromosome fusion. This is one of the few cases reported with terminal translocations (not jumping) preserving the subtelomeric region and highlights the importance of subtelomeric probes in terminal arrangements, and the utility of molecular probes, such as MLPA in defining this kind of abnormalities. In the clinical context, the patient presented a high proportion of 9p trisomy features which is expected considering the large 9p segment involved and the presence of the critical region 9p22.",,,,,,,,,"http://hdl.handle.net/20.500.12104/43969","http://www.scopus.com/inward/record.url?eid=2-s2.0-84908153588&partnerID=40&md5=593e87a378d461f6e43ef007debbaa87",,,,,,"3",,"Genetic Counseling",,"289

Andina, D.",,"2014",,"Breast cancer remains a leading cause of death among women worldwide. Mammography is one of the non-invasive methods to find breast tumors, which is very useful in the detection of cancer. Microcalcifications are one of the anomalies of this disease, and these appear as small white spots on the images. Several computer-aided systems (CAD) have been developed for the detection of anomalies related to the disease. However, one of the critical parts is the segmentation process, as the rate of detection of anomalies in the breast by mammography largely depends on this process. In addition, a low detection endangers women´s lives, while a high detection of suspicious elements have excessive cost. Hence, in this work we do a comparative study of segmentation algorithms, specifically three of them derived from the family of c-Means, and we use the NU (Non-Uniformity) measure as a quality indicator of segmentation results. For the study we use 10 images of the MIAS database, and the algorithms are applied to the regions of interest (ROI). Results are interesting, the novel method of subsegmentation allows continuous and gradual adjustment, which is better adapted to the regions of micro calcification, and this results in smaller NU values. The NU measure can be used as an indication of quality, which depends on the number of pixels and the homogeneity of the segmented regions, although it should be put in the context of the application to avoid making misinterpretations.
