Modified inverse square sensitometry for the determination of the characteristic curve of radiographic screen/film systems.
To determine the characteristic curve of the radiographic screen/film systems in a short focal spot-film distance, the inverse square sensitometric method was modified by changing the radiation intensity with two kinds of filters. The characteristic curves obtained in the two exposure series with these two kinds of filters were overlapped to obtain a complete one. The characteristic curve thus ...
متن کاملDisplay Control of a Crt - Film Scanning System
Characteristic of data reduction systems using on-line film digitizers, in high-energy physics, is the requirement to process large numbers of similarly formatted photographs. Anywhere from lo* to lo6 events or potential events, usually recorded on 35-mm or 75-mm film, must be analyzed with each experiment. The problem is then a large scale reduction of film data to an output of meaningful phys...
متن کاملCRT-D or CRT-P in CRT-indicated patients?
HRV parameters and 6-minute walking test, functional capacity, right ventricular systolic function, BNP and hs-troponin-I levels. Most common cause of death in these patients is arrhythmia, and autonomic dysfunction may be triggering factor (2). HRV parameters are now being used for prognostic evaluation in PAH patients. There are also studies suggesting HRV reduction may be associated with mor...
متن کاملThe risk of ventricular arrhythmias in a Dutch CRT population: CRT-defibrillator versus CRT-pacemaker
BACKGROUND Patients eligible for cardiac resynchronisation therapy (CRT) have an indication for primary prophylactic implantable cardioverter defibrillator (ICD) therapy. However, response to CRT might influence processes involved in arrhythmogenesis and therefore change the necessity of ICD therapy in certain patients. METHOD In 202 CRT-defibrillator patients, the association between baselin...
متن کاملCryptanalysis of Dual CRT-RSA
Several schemes under the framework of Dual RSA have been proposed by Sun et al (IEEE-IT, August 2007). We here concentrate on the Dual CRT-RSA scheme and present certain range of parameters for which this is insecure. As a corollary of our work, we prove that the Dual Generalized Rebalanced-RSA (Scheme III of Sun et al) can be efficiently broken for a significant region where the scheme has be...
