Sensitometric Control of Roentgen Film Processors

Optimal sensitometric curves of Kodak EDR2 film for dynamic intensity modulated radiation therapy verification

PURPOSE To investigate the optimal sensitometric curves of extended dose range (EDR2) radiographic film in terms of depth, field size, dose range and processing conditions for dynamic intensity modulated radiation therapy (IMRT) dosimetry verification with 6 MV X-ray beams. MATERIALS AND METHODS A Varian Clinac 23 EX linear accelerator with 6 MV X-ray beam was used to study the response of Ko...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Outline of Roentgen Diagnosis

This is a revised edition of the text of essentially the same title which was published in 1936, and, like it, is basically a handbook presenting the case for serum therapy in pneumonia. It should be noted, however, that the term "revision" does not always mean "reprinted," even though some of the phases of the problem as presented in the earlier edition are herein merely extended by the inclus...
