RADIO VISIO GRAPHY, Dr Anirudh Singh Chauhan

Clearing the doubts about IF or NOT to BUY RVG. Basic questions to ask self before investing, and what to look for while going for one.

1. DIGITAL IMAGING (RADIO VISIO GRAPHY) Dr. Anirudh Singh Chauhan

2. 1895: Wilhelm Conrad Roentgen  X-rays Two weeks after: Otto Walkoff : First dental x-ray ALARA principle “As low as reasonably achievable” 1987: First digital x-ray sensor for use in dentistry by Dr Francis Mouyen ( Later Marketed by Kodak). 2006: End of the film-base radiology ??

3. “Sharpen your diagnostic ability.” “...immediately enhance your diagnostic capabilities.”

4. “You may simply let the patients know that they’ll be getting about 90% less radiation than they would from a standard x-ray.”

5. “The images come up instantly as patients are in the chair; the images are so large that patients can’t help but become involved in the diagnosis.”

6. “Most patients are amazed at how quickly the image comes up on the screen and are impressed by its size.”

7. “Don’t have to spend a lot of time trying to sell the technology. Simply let patients know what it is and let them see the images.”

8. “Requires much lower exposure-times than film thus reducing the patient’s radiation consumption dose.”

9. “Patients will view the the doctor as making a more accurate diagnosis by using improved technology.”

10. ... The images can be immediately brought up on the screen for the patient to view and it can be magnified from 100% to 300%.”

11. “It combines superior design with outstanding performance, resulting in perfect quality x-rays.”

12. “It’s been more than 100 years since X-rays were invented.” Radiographic imaging process has not been changed much.

13. Standard Radiographs Image receptor: film Image processing: photochemical (developing, fixing, washing/rinsing, drying) Viewing: radiograph on illuminator Storage: radiograph

14. Digital Images Image receptor: CCD or screen Image processing: cpu and software or laser, cpu and software Viewing: image on screen or print-out Storage: on disk or paper hard copy

15. Advantages/Disadvantages Radiographs vs. Digital Images portable not portable familiar can be viewed by all initially inexpensive must send by mail one viewer new technology must have hardware/software inexpensive after initial investment transmissible by wire* viewed simultaneously

29. Advantages/Disadvantages Radiographs vs. Digital Images film size similar to beam size film covers larger area receptor size smaller than beam size receptor covers smaller area

30. Advantages/Disadvantages Radiographs vs. Digital Images film disposal no film disposal chemical/silver disposal film placement is easy no chemicals cable connection interferes with placement

31. Digital Imaging: Most significant advantages: - Computer-aided image interpretation - Image enhancement - Image archiving - Image retrieval

32. Digital Imaging More Advantages No Chemical processing No Hazardous wastes Images can be transferred electronically Patient Education Time Less Radiation

33. Radiovisiographic image with contrast effect of the upper right canine after root canal obturation made by the manual lateral-vertical technique of gutta-percha compaction

34. A marked area of the apical portion of the root for zooming in ‘window’ format

35. Three-dimensional analysis showed overfilled obturation mass as mild bulging at the very end of the root canal

36. Digital Imaging Disadvantages Cost new technology = uncertainty -rigidity and thickness of the sensor System crash Infection Control a challenge :- (sensor cant be sterilized) unknown sensor lifespan

49. So, what should one look for?

50. So what should one look for...? Do I need this now? How many operatories are equipped with tubeheads ? Are you & your staff willing to learn new techniques? Can I communicate with other practitioners (or other offices)?

51. How easy is it to back up the images? Can I get upgraded software and if so, what would it cost? How is servicing handled? Cost, availability, time to arrive? So what should one look for...?

52. Both Happy Families But you have to keep on be upgrading yourself (As and When BUDGET allows!!)
