Question 51

Heart Rate 80bpm, Trigger delay 50ms, Trigger window 10%, what is the available imaging time?

Answer 51

625 ms 60000 ÷ 80 = 750ms. 750 – (75\<10% of 750\> + 50 ---125) = 625 ms total available imaging time.

Question 52

Calculate the available imaging time for a patient with a HR 60 beats/min, trigger window 10% and trigger delay of 50ms.

Answer 52

850 ms

Question 53

Calculate the effective TR for a patient with a heart rate of 60 beats / min.

Answer 53

1000 ms If the heart rate is 60 beats per minute, the R-R interval (effective TR) would be calculated as such: 60,000 milliseconds (60 seconds per minute, and there are 1000 milliseconds per second) ÷ 60 (heart rate) which = 1000 milliseconds TR.

Question 54

Calculate the effective TR for a patient with a heart rate of 85 beats / min.

Answer 54

706 ms 60,000 / 85 = ~706
