This paper introduces the setting and configuration of our hospital's fPACS workstation, which is developed by the First Military Medical University. The fPAX video workstations are used as the terminals, including fPAX sampling workstation for video, picture and number, fPAX diagnosis workstation, fPAX clinician workstation and fPAX consultation center workstation. The workstation is equipped with an IBM4 2G host computer, an 80G fixed disc, an EMS memory more than 512M and a SONY 21″ pure flat display. Our experience of building PACS workstation proves that the reasonable setting and configuration is helpful to save the money and increase the efficiency.

Objective To study the Value of low dose CT scanning with gas-contrasted and low window level in diagnosing gastro-colon lesions.Methods 126 cases suspected with gastro-colon lesions were randomly devided into two groups,group A(69 cases) were scanned with conventional water-contrast or non-contrast and conventional expose dose,and with conventional window level,group B(57 cases) were scanned with gas-contrasted and low expose dose,and using low window level.The images were evaluated by 2 experienced radiologists,the results including doctor's self-confidence and diagnostic accurate rate in both group A and group B were compared based on the endoscopic results.Results The diagnostic self-confidence of radiologists and the accurate rate in evaluating the lesions in group B were obviously superior to group A.Conclusion CT scanning of gastro-colon with gas-contrasted,low expose dose and low window level is markedly superior to conventional one.

Objective To design capsule of gas-produced powder.Methods Glutin capsule was prepared with 0.50g gas-produced powder medicine packed in.Objects were divided randomly into three groups,and were given 2,5,10 grains dose separately.Then every object was scanned by CT and their attitudes were investigated on taking the medicine.Results 2 grains dose produced less gas,and stomach cavity were not filly distended;5,10 grains dose produced more gas,and stomach cavity were filly distended.After 5 minutes,CT image displayed capsule did not produce gas fully;after 10 to 15 minutes,capsule produced gas fully;after 20 minutes,gas decreased.Objects could accept 2 or 5 grains dose,but unwillingly accepted 10 grains dose.Conclusion Capsule of gas-produced powder produces gas steadily and lasts long.5 grains dose is suggested and the patient should take scan 10~15 minutes after taking capsules.
