Question

Calculate the available imaging time for a patient with a heart rate of 90 beats/min, trigger window 15% and trigger delay of 80ms.

Answer 1

To calculate the available imaging time for a patient, we need to consider the heart rate, trigger window, and trigger delay. First, we calculate the time between beats. Then, we multiply this by the trigger window and subtract the trigger delay to find the available imaging time.

Step-by-step explanation:

To calculate the available imaging time for a patient, we need to consider the heart rate, trigger window, and trigger delay. First, we calculate the time between beats using the formula (66 beats/min) x √(1 - (
`v^2`/
`c^2`)) = 57.1 beats/min. Then, we multiply this by the trigger window (15%) and convert it to milliseconds. Finally, we subtract the trigger delay of 80ms from the result to find the available imaging time.

Let's plug in the values:

Time between beats = 57.1 beats/min x (15/100) min/beat x 60 s/min x 1000 ms/s = 514.5 ms

Available imaging time = 514.5 ms - 80 ms = 434.5 ms
