Abstract:

Bundle adjustment is one of the essential components of the computer vision toolbox. This paper revisits the resection-intersection approach, which has previously been shown to have inferior convergence properties. Modifications are proposed that greatly improve the performance of this method, resulting in a fast and accurate approach. Firstly, a linear triangulation step is added to the intersection stage, yielding higher accuracy and improved convergence rate. Secondly, the effect of parameter updates is tracked in order to reduce wasteful computation; only variables coupled to significantly

Abstract:

As is known to us, conventional photogrammetry uses the double phase stereopair for forward intersection, but this paper proposed a new method for 3D coordinates acquisition based on single camera. Under the defined relationship of the object relative position, three-dimensional coordinates can be obtained by space resection through single photo. The principle of this method is simple but practical, especially suitable for measuring the overall mobile objects. Experiments show that within1500mm, plane normal direction is better than 0.02°in the measurement accuracy , and can replace stereopair

Abstract BACKGROUND The endoscopic endonasal approach provides a direct route to ventral foramen magnum (FM) lesions like meningiomas, which are difficult to access. Endonasal access at the FM is limited laterally by the occipital condyles and inferiorly by the C1 anterior arch and the odontoid process, which may need partial resection. OBJECTIVE We investigated the surgical anatomy and technical nuances for endonasally increasing the surgical corridor at the FM region both laterally and inferiorly.

Abstract:

Abstract Sarcoma is a heterogeneous group of connective tissue cancers with over 60 subtypes. Curative treatment relies on surgical resection combined with radiation. In the event of metastasis, chemotherapy is used but generally only with palliative intent. Given the heterogeneity of sarcomas, targeted therapies are limited, which has contributed to the relatively stagnant survival rates seen in the past decades. Objective: Personalized treatments, such as adoptive cell therapy (ACT), may be promising for select sarcoma patients, specifically those with Undifferentiated Pleomorphic Sarcoma (U

Abstract. 3D building modelling has been turned to be one of the most interesting and hottest subjects in photogrammetry in last two decades, and it seems that photogrammetry provides the only economic means to acquire truly 3D city-data. Most of the researches proposed methods for 3d building modelling in LoD2 using aerial images and LIDAR data and the produced models will be enriched by oblique images, therefore there is always a demand for a user to interpret the façade or in other manual building reconstruction process the operator should draw boundaries to represent the building model and

Abstract:

Short bowel syndrome is a pathological symptom complex that occurs after removal (resection) of the small intestine (more than 25% of its length), or when there is a signifi cant violation of its function. The most common cause of short bowel syndrome is adhesions of the small intestine that occur after surgical interventions on the abdominal organs. A description of the clinical observation of short bowel syndrome with severe manifestations of enteric insufficiency in a 41-year old patient is given. The patient was admitted to the surgical Department of FGBUZ Central clinical of the hospital

Objectives: Pertaining to peculiar designs of current knee prostheses, more bone is removed from posteromedial femoral condyle than posterolateral condyle to obtain desired femoral component rotation. The aim of our study was to evaluate whether there is a correlation between the asymmetry of the cuts and the femoral component rotation in total knee arthroplasty. Methods: We built a model to simulate anterior chamfer cut (ACC) performed during total knee arthroplasty for measuring posterior condylar offset (PCO).

Abstract:

Abstract Aim The circular stapled (CS) technique with transoral placement of the anvil is commonly used to perform the esophago-gastric anastomosis during minimally invasive esophagectomy (MIE). The procedure is safe, efficient and highly reproducible, however the intersection between the circular plane of the stapler and the linear staple line of the esophageal stump can expose the anastomosis to the formation of dog ears and therefore increase the risk of anastomotic leakage (AL). We describe a simple modification of the CS technique that avoid the formation of staple lines intersection. Bac

Background: Anastomotic leakage is a serious complication in colorectal surgery, often associated with higher morbidity and mortality. Even with advances in medical technology and devices, the rates of anastomotic leakage is not on downward trend.

Abstract:

Over the past decade, lung cancer treatment has undergone a major paradigm shift. A greater understanding of lung cancer biology has led to the development of many effective targeted therapies as well as of immunotherapy. Immune checkpoint inhibitors (ICIs) have shown tremendous benefit in the treatment of non-small cell lung cancer (NSCLC) and are now being used as first-line therapies in metastatic disease, consolidation therapy following chemoradiation in unresectable locally advanced disease, and adjuvant therapy following surgical resection and chemotherapy in resectable disease.

Abstract:

IntroductionNarrow Band Imaging (NBI) is an endoscopic visualization technique useful for upper aero-digestive tract (UADT) cancer detection and margins evaluation. However, NBI analysis is strongly operator-dependent and requires high expertise, thus limiting its wider implementation. Recently, artificial intelligence (AI) has demonstrated potential for applications in UADT videoendoscopy. Among AI methods, deep learning algorithms, and especially convolutional neural networks (CNNs), are particularly suitable for delineating cancers on videoendoscopy.
