Dr Raza Laskar, 32, from Ashton-under-Lyne, Greater Manchester, was arrested in a police operation targeting men who accessed online images of abuse. He was caught with more than 1.2m images, Manchester Crown Court heard.
NHS England confirmed Laskar worked in a number of Greater Manchester Hospital but the charges were not work-related.
In May, police executed a warrant at Laskar's home after 1,605 files believed to contain indecent photographs of children were uploaded from an IP address at his home.
The files had been uploaded between Christmas Day 2013 and January 2014.
Police found hundreds of chat logs and videos of Laskar engaging in sexual acts with a child who had been taken to a hotel room he had booked.He pleaded guilty at at an earlier hearing to 31 charges including sexual activity with a child and possessing images of abuse.
Det Sgt Guy Laycock of Greater Manchester Police said: "Laskar was a paediatric doctor who spent his working day with children. He has an affinity with them and knows how to engage and communicate with them.
"A significantly aggravating factor is that he used this knowledge to incite and groom his victims, all of whom were very young, vulnerable boys."
