Résumé
Para la radiografía digital se requieren circuitos que realicen la recepción y procesamiento de señales nucleares de múltiples canales simultáneamente. Estos circuitos se deben someter a pruebas para caracterizar su funcionamiento. En este trabajo se describen pruebas automatizadas para controlar por software desde una computadora personal la caracterización de un sistema basado en circuitos integrados específicos del tipo RX64DTH con detectores de microbandas y se muestran los resultados.
Circuits that carry out the signal acquisition and processing by multiple channels are required in digital radiography. These circuits should be tested in order to characterize their performance. This paper describes an automated system to control (by a software, from a personal computer) the characterization of a system based on RX64DTH specific integrated circuits with microstrip detectors. The results are shown.
Résumé
Objective: To investigate the effects of Kangguzhe Formula(KGZF) on promoting union of experimental rat fracture.Methods: The experimental rat fracture models were reproduced by cannon born injure,continually treated with KGZF 21d by oral administration.The X-ray,pathological histology and anti-fracture intension of fracture union tissue were detected to investigate the effects of KGZF.Results: KGZF can significantly improve the osteotylus rebuild,trabeculation of bone and concentrated osteoblasts of fracture tissue;X-ray detection also showed that it can increase the grade of X-ray and anti-fracture intension of fracture union tissue;Compared with model group,it had significant difference.Conclusion: KGZF can obviously improve the union of experimental rat fracture.
