Are we ready for Digital Pathology?

1. Hungary

2. Our company

3. Our product portfolio

4. Why we decided to use area scanning, why not the linear one?

5. The comparison of the 2 scanner technologies

6. The role of digital slides in education

7. Our new flash scan technology

9. Our future developments

You will hear now about:

A little bit about Hungary

What you may not know…

This video clip shows the most famous inventions!

Hungary is famous not only about „GULASH”,

but also about science:

We have 14 Nobel laureates for a population of 10 millions

1905 – Fülöp Lénárd in physics

1914 – Robert Bárány in medicine for „pathology of the vestibular apparatus”

1925 – Richard Zsigmondy in chemistry

1937 – Albert Szent-Györgyi in medicine for „vitamine C”

1943 – György Hevesy in chemistry

1961 – György Békésy in medicine for „discovery of the physical mechanism of

stimulation within the cochlea”

1963 – Jenő Wigner in physics

1971 – Dénes Gábor in physics

1976 – Milton Friedman in economics

1986 – János Polányi in chemistry

1994 – György Oláh in chemistry

1994 – János Harsányi in economics

2002 – Imre Kertész in literature for his roman „Fateless” written in 1992

2004 – Ferenc Herskó in chemistry

(Spain has a population of 46 millions and 8 Nobel laureates, 2 of them in medicine)

• private owned spin-off company born at the

Semmelweis Medical University in Budapest

Why we decided for AREA Scan technology?

• similar quality can be achieved, both technologies have minor advantages

• Advantages: • Area: Extended Focus is possible • Line: Sample topography can be followed better

• Speed:

• „MIRAX” technology of 3DH @ 43x (0.23µm / pixel resolution) is similar to Hamamatsu and Leica but faster, than Aperio!

• New „FLASH” technology is already faster than all current competition!

Area vs. Line scanning in BF

Current „MIRAX” technology has similar image quality as competition. Some say it’s better, some say others are better, therefore very subjective.

New „FLASH” technology proved to be the best by very thorough testing at the 1st European Scanner Contest. 41 pathologists did the evaluation!

Bottom line: our current technology is in the same ballpark as competition and the new one is already significantly better as competition.

Image quality in Brightfield –

AREA vs. LINE scanning

Area scanning gives us

the ability to extended

depth of field

Advantages of AREA vs. LINE scanning

in brightfield

Lower N.A. is better, because the depth of field is larger

A typical histological section thickness is 3-5 µm, a smear thickness is 10-15 µm. A maximum of 0.84 µm depth of field difference between the best and worst objective doesn’t really matter!

Competitor’s argument for having low

Numerical Aperture

Numerical Aperture (NA)

Depth of Field [µm]

Roche (ex BioImagene) Olympus 0.5 (worst) 1.99

Leica (own objective) 0.65 1.68

Aperio (Olympus Plan-Apo) 0.75 1.31

Hamamatsu (Olympus Plan-Apo) 0.75 1.28

3DHISTECH (Carl Zeiss Plan-Apo) 0.8 NA (best) 1.15

• Line camera sensor needs the stage move continuously!

• CCD camera (area) sensor doesn’t need this: we can stop the stage!

• Why is this so important?

• Area sensor makes possible: • Extended Focus - FISH! • Z-Stack, perfect co-localization – FISH! • Change the filter as many time as we want • Have any exposure time we need • Live image

Advantages of AREA vs. LINE scanning

in fluorescence

• In fluorescence the amount of light is the main limitation

• Area sensor (3DHISTECH) collects much more light than TDI sensor (Aperio, Hamamatsu) because the sensor area is larger.

Imaged area / Magnification AxioCam %

Aperio 5 383 µm2 / 43x 4 %

Aperio 21 531 µm2 / 21x 14 %

Hamamatsu 13 867 µm2 / 21x and 43x 9 %

3DHISTECH old FL camera

150 135 µm2 / 31x 100 %

3DHISTECH new FL camera

270 400 µm2 / 31x 180 %

Advantages of AREA vs. LINE scanning

in fluorescence

Competition uses 200 Watt arc lamp. We tested it and it wasn’t better than the HXP-120. Light amount from the bulb is higher but light density is lower.

Light source

Aperio Metal Halide lamp

Hamamatsu Metal Halide lamp

3DHISTECH Metal Halide lamp or Solid State lamp

Bit depth (information in image)

Aperio 10 bit

Hamamatsu 8 bit

3DHISTECH 12 bit with AxioCam

16 bit with new PCO.edge camera

Advantages of AREA vs. LINE scanning

in fluorescence

Brightness Index = NA4 / Magnification2

• 3DH = 0.804 / 202

• Aperio = 0.754 / 202 • Hamamatsu = 0.754 / 202

• Leica = 0.654 / 202

Conclusion: Our objective collects 30% more light, than Aperio or Hamamatsu and 230% more light, than Leica

Advantages of AREA vs. LINE scanning

in fluorescence

Main features of Pannoramic 250 Flash

How fast is it?

On the 1st European Scanner Contest (2010) each vendor scanned

the same 35 slides total area of 42,7 cm².

P250 FLASH is 3 times faster, than SCAN 150 & at least 2 times faster than Leica, the winner in 2010
