Opis:
This paper presents a methodology that addresses important issues concerned with the optimization of the misregistration measures in the volumetric medical data registration problem. Our registration framework uses robust simulated annealing method to handle multiple local minima of the cost function. Our efforts have been centred on obtaining a reliable, efficient and generally applicable method to solve such optimization problems. This has been accomplished through developing an adaptive cooling schedule for the simulated annealing method. The proposed method is very reliable for the estimation of the global minimum in the optimization of objective functions with highly differentiated search space landscapes. We present the detailed description of the method as well as discussion of its advantages and disadvantages.

Opis:
The alignment of volumetric datasets is an important problem in the processing of medical data. It is a prerequisite to numerous image based applications in diagnostic and therapeutic routines. In this paper, a new method is proposed for matching of 3D intramodality medical images. Our approach is based on some generalization of feature distance definition. Analogous to the standard surface matching, our algorithm uses also the chamfer distance like metric to define the quality of match function, however, the evaluation of the distance map is performed in a different way. The s-distance method is a step towards an automatic extraction of features, where each feature’s role in the registration process is weighted based on its relative statistical or spatial significance. As an alternative to the user-dependent non-automatic registration methods this approach offers a good assessment of similarity in the intramodality case. The elimination of less significant features in the registration process has resulted in a greatly improved efficiency over the voxel-based methods. Studying certain properties of the search space topography provides some insights into the performance of the proposed method as well as the standard registration algorithms in the rigid body registration problem.

Opis:
The paper presents the analysis of the economic and environmental effect of land consolidation on the example of the village of Hucisko situated in the administrative district of Leżajsk, Podkarpackie Province. Rural areas in Poland need changes related with an improvement of their competitive position in the European market. The object of the study is situated in the Podkarpackie Province which is characterized by fairly high land fragmentation and the occurrence of irregular-shaped and relatively small plots. Farms in South and South-Eastern Poland require modification with regard to their size or to the shape of their area. Within the area under analysis, land consolidation was performed in the years 2011–2013. The main purpose of the consolidation was to eliminate the troublesome checkerboard of fields. The performed land consolidation contributed to a significant improvement of living and work conditions of the local inhabitants. It can be also stated that the quality of the environment and the cultural values of the village have been enhanced.

The article presents a spatial analysis of rural areas in 14 villages in the Białaczów commune. The study has focused on land tenure and use as well as land fragmentation in private farms. On the basis of a synthetic fragmentation index of registered parcels a detailed research of private land fragmentation in villages of the Białaczów commune was carried out. The index calculated for each area allowed to distinguishing four types of villages. The types differ according to parcels’ fragmentation, a factor that may be one of the criteria in establishing which villages require land consolidation and land exchange works in the first place.
W pracy przeprowadzono analizę struktury przestrzennej obszarów wiejskich w 14 wsiach gminy Białaczów. Badania objęły analizę struktury władania, użytkowania gruntów, a także rozdrobnienia gruntów gospodarstw indywidualnych. Szczegółowe badania rozdrobnienia gruntów indywidualnych we wsiach gminy Białaczów dokonano na podstawie syntetycznego wskaźnika rozdrobnienia działek ewidencyjnych. Obliczony wskaźnik rozdrobnienia dla każdego obrębu pozwolił na wydzielenie 4 typów wsi. Wydzielone typy wsi są między sobą zróżnicowane pod względem rozdrobnienia działek, co może stanowić jedno z kryteriów przy ustalaniu kolejności wsi do podejmowania prac scalenia i wymiany gruntów.

Opis:
Many medical diagnostics and treatment procedures in the oncology, cranio-maxillofacial surgery, radiotherapy and neurosurgery deal with volumetric as well as surface data. Tumor detection or generation of the virtual treatment scene involves using complementary data sets that are obtained from different sensors, for example MR and CT data, or by the same sensor at different epochs. The very need for registration arises from the fact that the complementary data sets are acquired by imaging devices using different spatial coordinate systems or/and the anatomically correct superposition of two data instances cannot be performed without locally applied elastic transformation. The volume or surface matching is therefore an essential task in these applications. From the mathematical point of view the data aligning problem is an optimization task, which can be solved by using deterministic or non-deterministic optimization algorithms. Depending on the data size and the complexity of required matching transformation the runtime behaviour of the registration methods can stretch out between real-time and many hours' computations. In this paper various applications of the same registration paradigm are presented and discussed. The wide spectrum of the medical applications shows the importance of the registration approach for the optimization of medical diagnostics and treatment.

Registration is an important component of many medical data processing applications. Particularly significant is its role in the correlation of volumetric medical data aiming at generation of virtual patient-specific anatomical models. Such models enable optimization of various diagnostic and therapeutical procedures. The importance of the virtual patient models is becoming increasingly recognized in modern medicine. The advantages of using such biomedical virtual models are analogous to the advantages of real system behavior simulation in the engineering or material sciences. In this work some numerical issues associated with the registration problem and the visualization challenges arising in the context of virtual anatomical models have been presented and discussed.

In accordance with statutory law, since 2004 sworn translators have been considered a profession commanding public trust. Among the many professional duties associated with sworn translators' performance, the regulations emphasize the duty to translate both spoken discourse and written texts with precision and faithfulness, and make sworn translators liable to disciplinary sanctions for poor quality work. The principles and rules for practicing the profession of sworn translator are enumerated in the Professional Sworn Translator’s Code of 2018.

Opis:
This paper reports on our experiences using datasets from the Visible Human Project in different biomedical applications. Introduced 1994 by the US National Library of Medicine the digitized multimodal anatomical datasets of the Visible Man have challenged the worldwide scientific community. A significant response to this challenge from several interdisciplinary research teams has emerged as a new area of research. This area requires close interaction and collaboration among anatomists, radiologists, computer scientists, mathematicians, engineers and physicians. The digitized volumetric images of the human body have been applied not only for the computer-aided exploration of the human gross anatomy, but also as structural input for the therapy planning and simulation systems. The importance of such virtual patient model is becoming increasingly recognized in modern medicine. To effectively use these specific datasets a sophisticated framework consisting of image processing, computer graphics and mathematical modelling methods is required. In this work various aspects of the developed framework are presented and discussed. Some preliminary results of our biomedical simulations are presented.

Opis:
This paper presents some results concerning the analysis of X-ray propagation through biological structures. We introduce a physical model of the phenomenon and a numerical method based on this model for simulation of X-ray radiation propagation. The proposed method enables generation of radiological projections like those in the computed tomography or microtomography. We have focused our attention on the attenuation of X-ray radiation in bone tissue. Our computational model enables simulation of radiation propagation in the virtual specimen. The virtual bone microstructures used in our experiments are derived from the microtomography datasets of real bone specimens. The main advantage of our approach is that we can change the microstructure of the virtual sample in many ways by using the image processing methods. Results presented in this paper contain simulations of X-ray propagation for modified and unmodified trabecular microstructures as well as the visualization of the radiation intensity distribution for the simulated cases. With this new simulation technique, it is possible for example to analyze the propagation of X-ray radiation for different pathologic types of bone microstructure (e.g. virtually generated osteoporosis).

Opis:
The reconstruction of the osseous structures in the pelvic region after bone tumour resection is highly complex and challenging. Up to now the reconstruction of the pelvis defects by autologous or allogenous grafts (for instance the fibula transplants) are highly unsatisfied because of large shape differences. Therefore there is a huge demand for patient-specific and anatomically shaped implants. Our pelvis reconstruction planning approach is based on the statistical shape model. For generation of the statistical pelvis shape model a large data pool of CT datasets has been collected. The following CT data segmentation and surface processing methods delivered the required pelvis geometries. Via Procrustes analysis of the collected pelvis surfaces the parameterized pelvis shape mean model has been calculated and the principal component analysis (PCA) [3] applied for estimating the anatomically optimal graft or implant geometry. We will demonstrate on the clinical pelvis reconstruction case that the using of statistical shape models in the oncologic surgery planning is robust and very promising method.

The paper presents the project of land protection from erosion in Wola Idzikowska village. Because of the type of soils and topography, about 37% of the land is threatened by medium and strong water erosion. Due to the lack of windbreak barriers, 70% of the area is threatened by wind erosion. In Wola Idzikowska village in the years of 2004–2006 land consolidation was conducted. Anti-erosion protection systems were designed but never realized. The assessment of causes of this condition, as well as new system of anti-erosion phyto-control works have been done. Afforestation of about 4.1 hectares of land, mostly fallow lands and wastelands was designed. The possibility of introducing 7.60 kilometers of shelterbelts as a windbreak barriers was also shown.

Opis:
The paper contains analysis of the anti-erosion system in the road gully in Wielkopole, Lublin Upland. The solution implemented in the gully’s bottom is effective against line erosion – there is no gully deepening. Lack of protection of slopes results in an intense earthmass movements. At the brim zone of the gully suffosion processes occur leading to the gully widening. The eroded material is accumulated on the road and colmatage drainage system of voivodship road no. 842, what is dangerous to traffic and generates expenses. That is why anti-erosion systems should be implemented comprehensively, protecting both the slopes and the bottom of gullies. Projects of such systems should be consulted with specialist.

We have focused our attention on the new navigation oriented aspects and procedures which facilitate and enhance the traditional treatment techniques. Many illustrations let better understand the complex technical dependencies between the main elements of this approach. The presented procedures permit more precise planning and performing of the surgical treatment, reducing intra-operative time and improving the post-operative outcome.

This paper presents a method for computer assisted selection of optimal donor sites for autologous osseous grafts in the craniofacial surgery. At the initial graft design stage the surgeon defines in the CT data set the shape of the bone segment to be reconstructed and in the donor region CT data set a set of constraints for the optimization task. This non-automatic step is followed by a fully automatic optimization stage, which delivers a set of sub-optimal and optimal donor sites for a given template. Such approach permits the surgeon to find the best site for harvesting the graft and enables an exact anatomical reconstruction of the osseous section.
