A thin target approach for portal imaging in medical accelerators.
A new thin-target method (patent pending) is described for portal imaging with low-energy (tens of keV) photons from a medical linear accelerator operating in a special mode. Low-energy photons are usually produced in the accelerator target, but are absorbed by the target and flattening filter, both made of medium- or high-Z materials such as Cu or W. Since the main contributor to absorption of...
متن کاملAccelerators for Medical Applications
About 50% of the ten thousands particle accelerators at present running in the world are devoted to medical applications. The main areas of use are: (i) radioisotope production, (ii) conventional radiotherapy with electron and photon beams, (iii) oncological hadrontherapy. In this review paper it is shown that in all these areas there are new developments which are scientifically interesting an...

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...

متن کاملA 3D thin nets extraction method for medical imaging
This paper presents a powerful tool designed to extract characteristic lines, called 3D thin nets, from 3D volumetric images. 3D thin nets are the lines where the 3D grey level function is locally extremum in a given plane. Recently, we have shown that it is possible to characterize 2D thin nets as the crest lines of the image surface. This paper generalizes this approach to 3D data having thre...
