OBJECTIVES To evaluate the performance of fine and cutting needles in computed tomography guided-biopsy of lung lesions suspicious for malignancy and to determine which technique is the best option for a specific diagnosis. METHODS This retrospective study reviewed the data from 362 (71.6%) patients who underwent fine-needle aspiration biopsy and from 97 (19.7%) patients who underwent cutting...
This paper presents a novel and scalable experimental platform for biomechanical analysis of tissue cutting that exploits a triaxial force-sensitive scalpel and a high resolution vision system. Real-time measurements of cutting forces can be used simultaneously with accurate visual information in order to extract important biomechanical clues in real time that would aid the surgeon during minim...
This paper presents a greedy randomized adaptive search procedure (GRASP) for the constrained two-dimensional non-guillotine cutting problem, the problem of cutting the rectangular pieces from a large rectangle so as to maximize the value of the pieces cut. We investigate several strategies for the constructive and improvement phases and several choices for critical search parameters. We perfor...
Image registration is a fundamental task in today's medical imaging. In particular for histological serial sectioning, where a three-dimensional object is cut into thin sections for a further microscopic analysis, registration leads to a three dimensional reconstruction of the sections. This reconstruction enables an exploration of the digitized data in any direction, not only in the cutting di...
PURPOSE Ablating and cutting vitreoretinal membranes using a 193-nm excimer laser-based microsurgical system. METHODS A 193-nm microsurgical system enables delivery of the beam into a fluid medium to cut preretinal and subretinal membranes. Two patients with proliferative diabetic retinopathy and one patient with proliferative vitreoretinopathy were treated with this new device. RESULTS Gen...
Gilmore and Gomory's algorithm is one of the better actually known exact algorithms for solving unconstrained guillotine two-dimensional cutting problems. Herz's algorithm is more effective, but only for the unweighted case. We propose a new exact algorithm adequate for both weighted and unweighted cases, which is more powerful than both algorithms. The algorithm uses dynamic programming proced...
conclusions available data implies that restorative therapies should focus on multiple targets and different intervals after injury. yet, if we understand the key and basic origin of the injury, we may develop effective, complete, safe, and continual procedures. materials and methods we downloaded and reviewed more than 170 full textbooks and articles in english from the literature pubmed, and ...
Cutting of the dental hard tissues is an integral part of restorative dentistry. Cutting of the root dentine is also needed in preparation prior to endodontic treatment, with significant commercial investment for the development of flexible cutting instruments based around nickel titanium (NiTi) alloys. This paper describes the evolution of endodontic cutting instruments, both in materials used...
