Abstract
Disclosed herein is an ultrasound system for accessing a vasculature of a patient. The ultrasound system is configured to depict an enhanced ultrasound image of a subcutaneous portion of the patient including an icon surrounding a target vessel depicted on the display. The icon indicates to a clinician the target vessel is within range of a percentage vessel occupancy or vessel purchase length depending on a size of cannula or angle of insertion. The icon can also indicate blood flow strength, vessel type, or vessel deformation. The enhanced image can further include cannula trajectory guidelines and visual alerts for the clinician if the cannula tip can potentially backwall the vessel. Additional icons can indicate obstructions disposed on the cannula trajectory.
