AbstractAbstract
[en] Some observations about quality control tests done in the tomographic system of Heart Institute are described. Among the tests, the traditional test of quality control with scintillation camera and the specific test for tomography systems are induced. The traditional tests are essential, but not sufficient for evaluating the Spect equipment and the specific tests have been effectuated in controlled conditions. (C.G.C.)

Apresentam-se algumas observacoes sobre testes de controle de qualidade no sistema tomografico do Instituto do Coracao. Entre os testes realizados incluiram-se testes tradicionais de controle de qualidade de camaras a cintilacao e testes especificos para sistemas tomograficos. Os testes tradicionais sao essenciais, mas nao suficientes para a avaliacao de aparelhos de Spect e os testes especificos devem ser efetuados sob condicoes cuidadosamente controladas.

AbstractAbstract
[en] The measurements reported are intended to show the image quality as a function of different types of fluoroscopic screens. The reference criterion for the image quality is the signal-to-noise ratio at 10 lp/cm-1. The testing method explained allows assessment of new materials with a better accuracy than before. The testing of an Odelca unit, for instance, is feasible within less than a minute after test film processing. (DG)

Durch objektive Messung wurde der Einfluss unterschiedlicher Leuchtschirme auf die Bildguete erfasst. Als Mass fuer die Bildguete ist das Signal-Rausch-Verhaeltnis bei 10 lp/cm-1. Die Methode bietet die Moeglichkeit, mit groesserer Genauigkeit neue Materialien auf ihre Wirksamkeit zu pruefen. Die Pruefung einer Odelca-Anlage dauert nach Entwicklung des Testfilms weniger als 1 Minute. (DG)Original Title

AbstractAbstract
[en] Product tolerance requirements for small, cylindrical, piece parts produced on swiss automatic screw machines have progressed to the reliability limits of inspection equipment. The miniature size, configuration, and tolerance requirements (plus or minus 0.0001 in.) (0.00254 mm) of these parts preclude the use of screening techniques to accept product or adjust processes during setup and production runs; therefore, existing means of product acceptance and process adjustment must be refined or new techniques must be developed. The purpose of this endeavor has been to determine benefits gained through the implementation of a process acceptance technique (PAT) to swiss automatic screw machine processes. PAT is a statistical approach developed for the purpose of accepting product and centering processes for parts produced by selected, controlled processes. Through this endeavor a determination has been made of the conditions under which PAT can benefit a controlled process and some specific types of screw machine processes upon which PAT could be applied. However, it was also determined that PAT, if used indiscriminately, may become a record keeping burden when applied to more than one dimension at a given machining operation

AbstractAbstract
[en] After an analysis of the regulatory point of view, the quality control system which has been established for the radiopharmaceutical preparations and the medical analysis products marketed by the CEA-DRIS is described with regards to the means and the use. This system answers the criteria of efficiency and security allowing a suitable use of the products. The continuous evolutions of the regulations inducing quality control system improvement is emphasized

AbstractAbstract
[en] The limiting effects to the stability of optical frequency standards has been assessed. The stability of such a standard depends critically on the spectral width of the atomic absorber. The limiting stability is explored in the absence decoherence (interrogation time limited) and in the more realistic case where optical decoherence and radiative decay are present. The role of motional decoherence in an ion trap system is also discussed. (author)

AbstractAbstract
[en] Image quality control measurements for fluoroscopic screens and photofluorographs have shown that both types of equipment have a long operating life, so that constancy and technical performance tests are absolutely necessary. It is recommended to conclude in-service maintenance contracts with the manufacturers. (DG)
