3. Medical Technology
• The purpose of medical technology is to extend and improve life
by alleviating pain, injury and handicaps.
• Billions of people rely on medical technology in their homes, at
doctors offices, and in hospitals.
• More than 500,000 products are available today, such as
wheelchairs, pacemakers, glasses, and bandages.

4. Types of Medical Technologies
• Currently Used Medical Technology
• 3D Ultrasounds
• Newly Released Medical Technology
• Microfluidic Chip to Diagnose Flu
• Dental Technology Advancements: Less invasive procedures and better
experience for patients and dental professionals
• Digital X-Rays
• Intra-Oral Camera
• Periodontal Laser

5. Currently Used Medical Technology:
3D Ultrasounds
• 3D ultrasound is a medical ultrasound technique,
often used in obstetric ultrasonography (during
pregnancy), providing three dimensional images of
the fetus
• 3D ultrasounds allow one to see the width, height and depth of
images in much the same way as 3D movies but no movement is
shown

6. 4D Ultrasounds
• 4D fetal ultrasounds are also offered. 4D ultrasounds are similar to 3D
scans. 4D allows a 3-dimensional picture in real time, rather than
delayed, 4D is similar to a movie compared to a still picture.
• The best time to have a 3D or 4D ultrasound is
when you are between 26 and 30 weeks pregnant.
Before 26 weeks your baby has very little fat under
His/her skin, so the bones of her/his face will show
through the skin

7. 3D Ultrasounds: Pros
Pros
• Provides a detailed image of the baby,
more lifelike
• 3D/4D is a keepsake ultrasound
• Can be used to educated women about
abortion

8. 3D Ultrasounds: Cons
Cons/Risks
• The clinics that offer these services are not
currently regulated or approved by health
regulatory bodies in Canada.
• Long-term effects of ultrasound are unknown and
ultrasound that are just used for a picture and not
for a medical purpose could put both mother and
baby at an unnecessary risk
• According to Health Canada, there is "suggestive
evidence" that ultrasounds can have a biological
effect on the fetus.

9. 3D/4D Ultrasounds
Risks of an ultrasound depends on the
following factors:
• Duration of ultrasound exposure
• Intensity of ultrasound waves
• Frequency of ultrasound sessions

10. How to Reduce Ultrasound Risks
• Provide adequate training to ultrasound technologists
• Safety inspections of the clinic
• Regular inspections and maintenance of the
ultrasound machine
• Limit ultrasound sessions to last no longer than
30 minutes
• Limit ultrasound sessions to no more than
once a month
• Require proof of prenatal care prior to the 3D
ultrasound session

11. Newly Released Medical Technology:
Microfluid Chip to Diagnose Flu
• In 2009, the H1N1 flu spread across 200
countries and killed more than 18,000 people
in the world
• During this time, diagnoses often took too
long and false negatives were frequently
seen
• For these reasons, researchers at US
Universities performed a four year study to
develop an alternative that would be as
accurate as lab-scale diagnostics

12. Microfluid Chip to Diagnose Flu
• A microfluid chip was developed in early 2012
• A sample is taken and the chip extracts RNA
from signature proteins from the influenza
virus and converts it into DNA
• The DNA then replicates enough to be
detected by the reader
• It has been found that the chip actually
outperforms common flu diagnostics in
accuracy

13. Microfluid Chip to Diagnose Flu
• The microchip is currently the size of a standard
microscope slide
• It currently costs $10 a chip and results are produced
within a few hours
• The research team is continuing to work on improving
the chip so it costs $5 a chip and produce results in an
hour
• A faster, more affordable test with fewer negatives
could help minimize outbreaks and ultimately save
lives

14. Microfluid Chips to Diagnose Flu: Pros and Cons
Pros
• Fast: Results can be seen
within hours
• Disposable to reduce risk
of cross contamination
• Accurate: outperforms
most commonly used flu
diagnostics
Cons
• Costly: $10 per chip
• Less environmentally
friendly due to increased
disposable slides
• Many people with the flu
do not actually seek
medical care

15. Dental Technology: Digital X-Rays
• X-Rays are essential for the diagnoses of dental
caries and periodontal disease
• Digital x-rays have many more advantages over traditional x-rays,
such as:
• Less radiation is required for digital x-ray
• More eco-friendly, traditional films use toxic chemicals to develop
the film, digital x-rays are scanned and can be reusable
• X-rays can be seen instantaneously on the computer and are easily
shared for referrals or insurance purposes

16. Dental Technology: Intra-Oral Camera
• Intra-oral cameras are used to capture magnified
images of specific areas of the teeth.
• This allows a patient to see what is going on in their
mouth which can be a great motivational tool for
improved self care.
• Images can be stored and used to compare the area of
concern in the future.

17. Dental Technology: Periodontal Laser
• Periodontal laser can help reverse the symptoms of
gum disease
• Laser is used to destroy bacteria and pathologic
proteins in the pocket of the gums
• This procedure reduces the need of scalpel and
stitches use
• Each patient is different but results from laser therapy
can be seen after just 1 treatment

18. Dental Technology: Pros and Cons
Cons
• Cost – Going digital is very
expensive
• Comfort – the sensor tends
to be thicker making it less
tolerable for the patient
• Many dental professionals
would need additional
training for use of the new
products
Pros
• Reduced radiation
• Faster to produce image
• No chemicals are used
for film development
• Images can be
manipulated to enhance
the colour, aiding in
diagnostics

19. Medical & Dental Technology Conclusion
• Risks need to be taken into consideration while using
technologies, such as the 3D ultrasound. Its important to
understand if the benefits outweigh the risks.
• The microfluid chip allows for easier and quicker results
• Dental technologies are useful tools for diagnoses, prevention and
patient education
• Overall, health technologies are essential for the public to live a
quality life, diagnose and prevent diseases and increase patient
comfort
• The technological advancements made today creates an exciting
outlook on what the future holds in medical sciences
