Abstract:Objective This paper aims to discuss the low radiography methods by comparison of
radiotherapy dose between head and neck combined with CT angiography (CTA) automatic and manual
triggering. Methods 60 patients with head and neck CTA were divided into A and B groups. Group A
selected tube voltage 100 mV, tube current 350 mA, injection flow rate of 4 mL/s, manual trigger at head
and neck CTA radiation doses; Group B selected tube voltage 100 mV, tube current 350 mA, injection
flow rate of 4 mL/s, triggered automatically by the detection layer at the head and neck CTA doses of
radiation. Results 60 patients of head and neck CTA carotid artery and its branches could all clearly
displayed and be able to meet the medical diagnostic requirements. Conclusion Manual trigger at the
head and neck CTA doses of radiation are greater than the automatic trigger for head and neck CTA
radiation dose.
