Injection Needles

In the current image-guided medication process, the practitioner first identifies the region of interest using an ultrasound probe. | The injected needle needs to travel through the body, passing internal body organs to reach the minute target area without causing a wound to the patient. | When the desired anatomy is in view, the practitioner estimates the needle trajectory and insertion point. | The inability to perfectly identify the needle tip makes it dangerous to advance the needle, leading to life-threatening seizures. | Physicians who perform injections often use needles and other sharp objects, which can be invasive to the human body.
