ALARA principle

  • We started this service knowing we had to not only to provide great imaging for doctors, but also deliver a significantly lower dose of radiation to their patients with each needed scan.
  • ALARA (As Low As Reasonably Achievable) is a radiation safety principle for minimizing radiation doses and releases of radioactive materials by employing all reasonable methods. This is one of the most important tenets upon which Allscan is founded.
  • CBCT has tremendous and numerous benefits. But in the interest of safety, we feel you should always co-review the risks vs. benefits of CBCT. The FDA has a great link to reference when consulting about CBCT.


CBCT versus helical CT has 98% less radiation dosing than traditional medical CT.

Below is a table that shows the relative radiation exposure of a CBCT compared to other forms of x-ray procedures.


Safety features of NewTom

  • SafeBeam™
    • Featured in all NewTom units, SafeBeam™ automatically adjusts the radiation dosage according to the patient’s age and size. As a result, patient exposure is tailored and image contrast remains consistent regardless of patient size or bone density.
  • Limited Fields Of View
    • Flexibility to scan your region of interest, ranging from 6×6 to 15×15
    • The advantage of using a small Field Of View (FOV) lies in the possibility of limiting the area of analysis, thus only irradiating a minimal anatomical region. A small field of view even offers the possibility of using HiRes mode, which allows the user to obtain better image quality.
