 ATTENTION ALL MEMBERS:
                   The field of radiation Oncology is progressing at a very brisk pace. So our members may be changing their work places. In their busy
 schedules, sometimes they forgot to update their location with us. We at AROI are taking care to update AROI database, so that all the information regarding
 AROI should reach them. This being election year, we would like to bring to the kind attention all our colleagues to spare some time to check their status on
 AROI website. and also update with Dr. Subhir Gangoly Election commissioner for Election. The procedure to view and update Bio-data on website is:
     1. Go to www.aroi.org
    2. Go to member login area on left area.
    3. Enter used ID as LM-XXXX (For LM-4 it is LM-0004, For LM-13 it is LM=0013
    4. Enter password (same as user ID that is LM-XXXX).
    5. If you want to update the date, please update it on the website & also send a mail to vashistha.aroi@gmail.com.
 Members can change their password once he / she has logged on at the website.
AROICON 2010 is being organized under the banner of Bihar Chapter of AROI Under the chairmanship of
