i-CAT Scanner

The Benefits of an In-Office cone beam scanner


The cone beam scanner by is a state-of-the-art imaging device. This machine produces a digital three-dimensional image of the jaws, allowing Dr. David R. Scharf to see the patient's anatomy without the distortion, magnification, restricted clarity, high radiation dose, or lack of accuracy in measurements found in other imaging systems. This means greater surgical predictability and reduced surgery time.

Dr. Scharf was one of the first periodontists on Long Island to offer this technology to his patients. Other dental offices that do not have this machine on site must give their patients a prescription to have a dentascan done at a radiologist's office. Their patients must call that office, make an appointment, drive to that office, fill out more paperwork, wait until they are called, and then have their scan. Then they must wait until their dentist receives the scan from the radiologist's office and make another appointment to get the results. By having the scan done right in Dr. Scharf's office at the time of appointment, our patients save time and hassle.


Minimized Radiation Exposure

We are always concerned about our patients' exposure to radiation. Our goal is to get the most diagnostic information with the lowest possible radiation dose. A common measurement of radiation dosage in the microsievert (Usv). This chart shows the radiation exposures of an i-CAT scan compared to other dosage sources.

i-CAT 20-second scan:

  • Exposure is in "Pulsed" mode; total exposure time is about 3.5 seconds for a 20-second scan
  • Most people are exposed to an average of 8Usv daily just from background radiation present everywhere. The typical 10-second scan used for dental implants exposes our patients to just 34Usv, or the equivalent of about 4 days of background radiation. A standard medical scanner exposes patients to 35–100 times this radiation dose.
