background: leptospirosis is a worldwide zoonosis causedby leptospira interrogans. leptospirosis results in decreasedmilk production, abortion, stillbirth, infertility and mortality,which causes financial loss in the cattle industry. objectives:the aim of this research was to perform a serological andbacteriological study of leptospirosis in 6 industrial dairy herdsand 3 feedlots with previous ...
Three-dimensional (3D) microscopic imaging techniques such as confocal microscopy have become a common tool in measuring cellular structures. While computer volume visualization has advanced into a sophisticated level in medical applications, much fewer studies have been made on data acquired by the 3D microscopic imaging techniques. To optimize the visualization of such data, it is important t...
Wide local excision (WLE) is a common surgical intervention for solid tumors such as those in melanoma, breast, pancreatic, and gastrointestinal cancer. However, adequate margin assessment during WLE remains a significant challenge, resulting in surgical reinterventions to achieve adequate local control. Currently, no label-free imaging method is available for surgeons to examine the resection ...
BACKGROUND The goal of limb-sparing surgery for a soft tissue sarcoma of the extremity is to remove all malignant cells while preserving limb function. After initial surgery, microscopic residual disease in the tumor bed will cause a local recurrence in approximately 33% of patients with sarcoma. To help identify these patients, the authors developed an in vivo imaging system to investigate the...
The work is applying an image segmentation to a micrograph which is showing the microscopic structures of a specimen of ductile cast iron. The segmentation allows the measurement of the size of the nodules.
BACKGROUND The treatment of trigger finger so far has heavily relied on clinicians' evaluations for the severity of patients' symptoms and the functionality of affected fingers. However, there is still a lack of pathological evidence supporting the criteria of clinical evaluations. This study's aim was to correlate clinical classification and pathological changes for trigger finger based on the...
Image deconvolution is an effective image restoration technique to improve the quality of digital microscopic images resulting from out-of-focus blur. To solve the severely ill-posed problem of traditional Richardson–Lucy method, considering the point spread difference of various directions, a new microscope image restoration method based on multiple defocused images of different aperture is pr...
The paper deals with the issue of multifocal image fusion. Two techniques of the hierarchical image representation are analyzed herein. The first one is hierarchical decomposition based on the Laplacian pyramid and the second one is based on integer discrete wavelet transformation. After the analysis of the above-mentioned decompositions techniques the algorithm of multifocal image fusion is de...
