the injection of the dye and for other individuals involved in the procedure. These
individuals could include medical staff or patient helper.

ICG timers can be configured to run separately or as a single combined timer. A timer is started by either
selecting the timer or when the initial image captured. The injection should be administered when the scan
head is aligned. If a timer is started accidentally you can reset it by selecting the timer and selecting
