Opis:
Selection of optimal treatment modality in a patient with cervical cancer depends on FIGO clinical stage. At stages IB2-IVA, the cornerstone of treatment is radiochemotherapy. As first step, patients undergo irradiation from external fields combined with chemotherapy (cisplatin, 40 mg/m2, QW). Brachytherapy is used as second-line treatment – an essential component thereof – enabling delivery of high dose of radiation to both genital organs and tumor. Quality of this treatment directly correlates with local control of the disease, long-term overall survival and quality of life of patients after completion of therapy. The paper presents current principles of high dose rate (HDR) brachytherapy in cervical cancer patients. Discussed are principles of two-dimensional (2D) planning, used to date in about 50% of brachytherapy centers worldwide, as well as three-dimensional (3D) magnetic resonance (MR)-based planning. As availability of MR in ours and many other oncology centers is limited, a computed tomography-based modification of gynecologic recommendations GIN GEC ESTRO has been suggested. Therapeutic areas are defined: high-risk clinical target volume (HR CTV) and intermediate risk clinical target volume (IR CTV) which may be safely contoured based on clinical exam and CT study, when no MRI is available. Acceptable doses for critical organs are listed. Based on own experience, indications and limitations for use of intraparenchymal (interstitial) and intracavitary applications were developed.
Wybór metody leczenia chorych na raka szyjki macicy jest uzależniony od stopnia zaawansowania, ocenionego według klasyfikacji FIGO (International Federation of Gynecology and Obstetrics). Zasadniczą metodą leczenia chorych na raka szyjki macicy w stopniach zaawansowania IB2-IVA jest radiochemioterapia. W pierwszym etapie przeprowadzane jest napromienianie z pól zewnętrznych wraz z chemioterapią z zastosowaniem cisplatyny w dawce 40 mg/m2, raz w tygodniu. W kolejnym etapie leczenia stosuje się brachyterapię. Brachyterapia jest istotną częścią leczenia, umożliwiającą podanie wysokiej dawki na narząd rodny wraz z guzem, a jakość tego leczenia ma wpływ na kontrolę miejscową nowotworu (LC), przeżycia odległe (OS), jak również na jakość życia chorych po zakończeniu terapii. W pracy przedstawiono zasady obowiązujące współcześnie podczas leczenia brachyterapią o wysokiej mocy dawki (high dose rate brachytherapy, HDR) u chorych na raka szyjki macicy. Opisano zasady planowania w systemie dwuwymiarowym (2D), stosowanym do dzisiaj mniej więcej w połowie ośrodków brachyterapii na świecie, oraz planowania w systemie trójwymiarowym (3D) na podstawie rezonansu magnetycznego (MR). Ponieważ dostępność MR w naszym i wielu ośrodkach onkologicznych jest utrudniona, zaproponowano modyfikację rekomendacji GIN (Gynaecological) GEC ESTRO dla potrzeb planowania, opierając się na tomografii komputerowej. Zdefiniowano obszary terapeutyczne: HR CTV (high-risk clinical target volume), IR CTV (intermediate risk clinical target volume), jakie można bezpiecznie konturować, opierając się na badaniu klinicznym i TK, przy braku MR. Opisano dopuszczalne dawki dla narządów krytycznych. Na podstawie własnych doświadczeń opracowano wskazania i ograniczenia w zastosowaniu aplikacji śródtkankowych i śródjamowych.

Opis:
The article addresses the three-dimensional (3D) underwater path planning problem of an autonomous underwater vehicle (AUV) in a time-varying current. A modified artificial potential field algorithm combining the velocity vector synthesis method is proposed to search for the optimal path. The modified potential field (MPF) algorithm is designed to dynamically plan the non-collision path. Meanwhile, this modified method is also proved to be an effective solution to the goals not reachable with obstacles nearby (GNRON), U-shaped trap, and rotation unreachable problems. To offset the influence of time-varying current, the velocity synthesis approach is designed to adjust the AUV movement direction. Besides, considering path planning in the complex underwater environment, the multi-beam forward-looking sonar (FLS) model is used. Finally, simulation studies substantiate that the designed algorithm can implement the AUV path planning effectively and successfully in a 3D underwater environment.

Opis:
The ocean is a formation that has a volume and consists of a surface layer of water, a column, and a bottom. Visualization of the sea on a digital map is important to support the acceleration of marine spatial planning (MSP), which is generally two-dimensional on a flat plane. A marine cadastre is defined as an instrument used in managing spatial boundaries, which describes, visualizes, and realizes legally defined boundaries as well as rights, restrictions, and responsibilities related to activities in the marine environment. Therefore, visualization in 3D will open a wider perspective than conventional maps. The 3D marine cadastral system was built using the Penanjung Bay pilot project and the QGIS2ThreeJS plugin with JavaScript. The results obtained can provide a 3D visualization of the position and boundaries for each component of the marine cadastre in Penanjung Bay with a broader picture of the sea spatial layout in the region.

Opis:
The complex geometry of the city structure and the increasing speed of ongoing urban transformations in large European cities, requires powerful tools for the analysis, design and management. Virtual 3D city models can be an important tool in urban planning, used to diagnose phenomena produced by tall buildings. In recent years, the issue has become a considerable challenge for the cohesion of the European urban landscape. This paper presents foundations of a research project under Polish-Norwegian financing mechanism called 2TaLL. The project examines possibilities and limitations of using virtual 3D models of cities to provide advanced urban analyses focused on simulating impact tall buildings have on landscapes of European cities. The research is an interdisciplinary combination of geo-information and urban planning and contributes to the development of theory & applications in the two fields of engineering science.

Purpose: According to the available international recommendations, at least one independent verifi cation of the calculations of number of monitor unit (MU) is required for every patient treated by teleradiotherapy. The aim of this study was to estimate the differences of dose distributions calculated with two treatment planning systems: Eclipse (Varian) and Oncentra MasterPlan (Elekta). Materials and methods: The analysis was performed for 280 three-dimensional conformal radiotherapy treatment (3D-CRT) plans with photon beams from Varian accelerators: CL 600C/D X6 MV (109 plans), CL 2300C/D X6 MV (43 plans), and CL 2300C/D X15 MV (128 plans). The mean doses in the planning target volume (PTV) and doses at the isocenter point obtained with Eclipse and Oncentra MasterPlan (OMP) were compared with Wilcoxon matched-pairs signed rank test. Additionally, the treatment planning system (TPS) calculations were compared with dosimetric measurements performed in the inhomogeneous phantom. Results: Data were analysed for 6 MV plans and for 15 MV plans separately, independently of the treatment machine. The dose values calculated in Eclipse were significantly (p <0.001) higher compared to calculations of OMP system. The average difference of the mean dose to PTV was (1.4 ± 1.0)% for X6 MV and (2.5 ± 0.6)% for X15 MV. Average dose disparities at the isocenter point were (1.3 ± 1.9)% and (2.1 ± 1.0)% for X6 MV and X15 MV beams, respectively. The largest differences were observed in lungs, air cavities, and bone structures. Moreover the variation in dosimetric measurements was less as compared to Eclipse calculations. Conclusions: OMP calculations were introduced as the independent MU verification tool with the first action level range equal to 3.5%.

Opis:
With regard to the municipal spatial policies, the issue of flood protection, and hence the directions of development of flood-endangered land seem rather significant, given the possible social and economic consequences of a wrong decision. Currently, there is no legal obligation, within the statutory activities of flood protection institutions, to implement guidance documents prior to the works on the municipality development. It is determined by the local government in the planning documents, which are in accordance with the applicable regulations, acts of local law. Space management, through planning development and land use or the landscape protection, requires the access to comprehensive and reliable information. GIS technology, 3D models and mathematical models using neural networks in spatial analysis and monitoring changes in space to protect flood risk land, give the possibility of collecting the information that constitutes the basis of knowledge on the area, which helps to make decisions regarding a purpose and a method of the land use. The data obtained in this way are a valuable source of knowledge on the stage of preparation of planning documents that determine the directions of municipal spatial development. Under the Act of 27 March 2003 on spatial planning and development [spatial planning and development act 2003], these documents are a municipal study of the conditions and directions of the spatial planning and a local zoning plan.

Opis:
The article explores the potential of using panoramic videography for the spatial engineering and spatial management of landscape. The concept of panoramic photography, as a basis for panoramic videography, has been widely used for visualisation of cultural heritage sites and documentation of various sites. Panoramas are widely used, for example, by Google in StreetView to present not only the cityscapes, but recently also rural landscapes. Panoramic videography is a process of creating panoramic (360-degree) video, which represents the dynamic environment. The land intensity factors (WIT - in Polish: "współczynniki intensywności terenu") introduced by Litwin is a method for evaluation of the landscape where different functions can be specified: agricultural, non-agricultural and recreational. Although this method can be used in different terrains, this article proposes to use panoramic video camera for the enhancement of the recreation function of WIT. The process of creating panoramic videography is explained in this article as it was tested and explored in the United Kingdom (in Launceston) and Poland (the district of Czarny Dunajec). It is based on gathering imagery not from airplanes but from a mobile setup that traverses through streets. What is more, the combination of vector and raster modelling of terrain in a visual and interactive environment has a potential to become a powerful tool for enhancement of land intensity factors. The administrative borders are one of the drawbacks for a determination of WIT and comparing them to terrain values. This article proposes the application of a path-based approach to visualize changes in land value and recreation function thanks to data collected from panoramic videography and information input to database. Annotations and measurements (panoramic photogrammetry) gathered from geo-referenced video provides a potential not only for determining WIT factors, but also for regional planning.
