A PICC line or central venous catheter is often placed for this purpose.

Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam.

Capsules see a more intense heating regime than spaceplanes and ceramics such as used on the Space Shuttle are usually less suitable, and all capsules have used ablation.

So once the physician verifies that the focus spot is on the target he has chosen, then we move to perform a full energy ablation like you see here.

Radioiodine ablation has been used for over 50 years, and the only major reasons for not using it are pregnancy and breast feeding (breast tissue also picks up and concentrates iodine).

Usually, laser ablation refers to removing material with a pulsed laser, but it is possible to ablate material with a continuous wave laser beam if the laser intensity is high enough.
