question 1- here is showing using a screen Monitor implanting a Stent in an artery -

,so is it using CT or XRAY to show the veins and stent being put in ?
question 2- Can this same type of Camera/video be used to take a Biopsy from a Lung Nodule , with a Biopsy needle and camera , or does this only show Veins and No nodules ??
