Dr. Gregory Kapordelis, 46, was convicted in May of six counts of downloading child pornography and using boys to produce pornographic pictures between 2001 and 2004.
He was acquitted of a seventh charge of making a video of himself having sex with a person under 18.
He was scheduled to be sentenced on Monday, but defense lawyers and prosecutors spent hours wrangling over objections that could shave years off the maximum prison sentence.
The sentencing is scheduled for 10 a.m. today and Dr. Kapordelis is expected to be given a chance to speak.
Dr. Kapordelis was originally charged with traveling to Russia to have sex with boys when he was arrested after landing at a New York airport in 2004.
Though those charges were later dropped, prosecutors filed a new round of charges after authorities said they found pornographic photos during a search of his home after the arrest.
During the May trial, prosecutors showed jurors what they said was a private file on Dr. Kapordelis' computer that contained images of young-looking males in sexual positions and activity on an online newsgroup called Pretty Boys.
Dr. Kapordelis's attorney had argued the pornography, found on computers in the doctor's Gainesville, Ga., home, could have been downloaded by others who visited or lived there - including teenage boys and another doctor who lived there while Dr. Kapordelis was overseas.
Each of the seven counts against Dr. Kapordelis carries a maximum penalty of 20 years in prison, but sentencing guidelines would likely not call for that strict a punishment if he is convicted.
