A three-dimensional (3-D) imaging system based on Gray-code projection is described; it thought to be used as an integration the already developed profilometer of multifrequency gratings. The method allows us evaluate 3-D profile objects that present even marked discontinuities surface, thus increasing flexibility measuring topology can measured. basic aspects for and profiling are discussed, with particular emphasis devoted study resolution analysis systematic errors. results this allow...
In the context of spreading interest in textbook outcome (TO) evaluation different fields, we aimed to investigate an uncharted procedure, that is, laparoscopic microwave ablation (MWA) for hepatocellular carcinoma (HCC). Absence post-MWA complications, a hospital stay three days, no mortality nor readmission within 30 and complete response target lesion at CT scan defined TO achievement. Patients treated between January 2014 March 2021 were retrospectively reviewed, 521 patients eligible...
In our laboratory, the performance of a 3D imaging system, based on structured light projection, has been improved by means development three procedures, which are (i) Gray Code projection Method (GCM), (ii) Phase Shift (PSM), and (iii) combination GCM PSM. this paper, all procedures described results measurement performed target objects presented. The analysis systematic height error due to crossed axes optical geometry system is performed, procedure for its compensation
In this paper, the analysis of measurement errors in an optical sensor for achievement 3D range images is presented together with procedures developed their compensation. The performs by means active stereo vision approach which correspondence problem solved projection structured light, basically consisting patterns fringes rectangular profile. Two have been identified: former, thereafter called 'waviness,' intrinsic to profile fringes. This error has dramatically reduced a filtering block,...
In this paper, a 3D measurement procedure is presented, which combines the gray code light projection technique and phase shift method. The aim improvement of performance imaging system based on structured projection. measuring demonstrates ability objects presenting marked discontinuities shape, such as steep slopes, grooves holes: experimental tests performed show that accuracy up to 0.42% precision 0.3% range. mainly limited by its resolution. To increase performances, method achieve...
In this paper, two measurement procedures, aimed at the improvement of performance an optical whole field profilometer based on grating projection, are presented. The first procedure is Gray code method. It performs a space encoding area and yields 3-D range images in which even sharp discontinuities object shape can be measured. second calibration components system, order to describe profile global coordinate limiting use reference surface only during profilometer. procedures detailed some...
Purposes: Patients with perforated peptic ulcer (PPU) present signs of sepsis and appropriate management can be offered to achieve an optimal outcome disease.We propose evaluating the severity intra-abdominal in case PPU a new score called TNM, name borrowed by cancer staging, aim assess its predictive value.Methods: We included 183 patients diagnosis complicated PPU.We defined categories T (Temperature), N (Neutrophils count) M (MOF); then, were grouped stages (0-IV).Variables analysed age,...
