Medical Cyclotron Used for Diagnostic or Therapy

Cyclotron operated within a hospital to deliver radiation to produce short life radioactive isotopes for diagnostic purpose is used in many hospitals. But cyclotron used for proton therapy is just at beginning. Proton beam therapy is a technologically advanced approach since it achieves precise radiation dose distribution. As the depth of penetration is a function of its energy, the point of energy release of the proton can be very precisely determined. The path of the proton beam is linear and causes very little secondary lateral scatter. Healthy tissues upstream from the tumor receive only a small dose and those located around the tumor and behind receive virtually none. Thus proton beam therapy is the most effective method. On the other hand, the cyclotron must be reliable, and the beam must be stable to ensure patient´s safety since the proton beam is used directly. Efficiency of beam delivery to the treatment rooms, raster scanning techniques to ensure the correct control of beam energy, intensity, and position stability, rapid and precise flexibility in changing beam parameter are also essential for satisfying clinical needs. The design efforts for developing a hsopital-based medical therapy cyclotron including the clinical beam delivery systems and integrated control system are really complex, and are less well developed than patients real need. A conception scheme for the purpose is proposed.

18F-FLT uptake can be used to monitor the biological response of esophageal SCC and normal tissue to RT. Increased uptake of 18F-FLT following treatment interruptions may reflect accelerated repopulation. 18F-FLT PET may have advantages compared to 18F-FDG PET in differentiating inflammation from tumor. 18F-FLT PET may help oncologists predict treatment response as early as one week after the beginning of treatment and estimate clonogenic repopulation during RT. 18F-FETNIM PET can depict hypoxia in esophageal SCC. Prior to CCRT, tumor hypoxia demonstrates spatial variability in different days, though overall 18F-FETNIM uptake remains similar. Baseline SUVmax may be predictive of treatment response.

Buildings are known to significantly affect the global carbon emissions throughout their life cycle. To mitigate carbon emissions, investigation of the current performance of buildings with regard to energy consumption and carbon emissions is necessary. This paper presents a process-based life cycle assessment methodology for assessing carbon emissions of buildings, using a multi-storey reinforced concrete building in a Sri Lankan university as a case study. The entire cradle-to-grave building life cycle was assessed and the life span of the building was assumed as 50 years. The results provide evidence of the significance of operation and material production stages, which contributed to the total carbon emissions by 63.22% and 31.59% respectively. Between them, the main structural materials, concrete and reinforcement steel made up 61.91% of the total carbon emitted at the material production stage. The life cycle carbon emissions of the building were found to be 31.81 kg·m−2 CO2 per year, which is comparable with the values obtained in similar studies found in the literature. In minimizing the life cycle carbon emissions, the importance of identifying control measures for both building operation and material production at the early design stage were emphasized. Although the other life cycle stages only contributed to about 5.19% of the life cycle carbon emissions, they should also receive attention when formulating control strategies. Some of the recommended strategies are introducing energy efficiency measures in building design and operation, using renewable energy for building operation and manufacturing of materials, identifying designs that can save mass material quantities, using alternative materials that are locally available in Sri Lanka and implementing material reuse and recycling. This study is one of the first to undertake a life cycle carbon emissions assessment for a building in the Sri Lankan context, with the hope of facilitating environmentally-friendly buildings and promoting sustainable construction practices in the country.
