Ultrasonic Exposure and Intensities 

8.1     Tissue Exposure to Ultrasound Energy 

The  ultrasound  energy  emitted  by  the  DGH  8000  is  low  intensity  and  will  have  no 
adverse effects on the patient and/or operator. However, the operator is still cautioned to 
perform  examinations  using  the  principle  of 

ALARA

  (As  Low  As  Reasonably 

Achievable).  All  examinations  should  be  done  so  that  the  patient  receives  as  little 
ultrasound  radiation  as  possible.  Do  not  hold  the  probe  against  the  eye  or  other  tissue 
with  the  system  activated  except  when  performing  an  exam.  Do  not  perform 
unnecessary exams. 

 

8.2    Ultrasonic Intensities
