RESUMO
Because of the bad definition of images in using DSA machine,the X-ray detector was used to check the DSA output dose so as to solve the image quality problems. Through checking the output dose,the problem were found in time and solved thoroughly,therefore it is very important to take image quality control at intervals.
RESUMO
DSA machine is very important for patient examination and therapy in medical imaging department. The management and maintenance of machine have direct impact on clinic diagnosis and treatment quality. Scientific management and maintenance for DSA machine are proposed to bring machine into full use, and the clinical need is explained in detail along with machine troubleshooting and maintenance, etc. It emphasizes the importance of relative machine aspects, especially of medical engineer's comprehensive ability. Those improve medical quality and machine life, and also improve financial and social benefit.
RESUMO
Objective To evaluate the value of Bolus technology for lower extremity. Methods The patients with diabetic foot or leg pain was examined with GE 3100 digital plate DSA machine and Bolus technology, which were suspected with lower extremity angiography. Results Bolus technology was valuable for the diagnosis of lower extremity arterial thrombosis. Conclusion Bolus technology is better than traditional DSA in the aspect of display of lower extremity vessel.
