well you ready i'm ready to go one thing well now the floor is all okay thank
00:00:07
you good morning everybody is a great pleasure to be here ampersand great x. ray
00:00:12
my name is martin chowder um as you certainly know breast cancer is the most common cancer norman and the
00:00:18
world health organisation has estimated that about one point seven
00:00:22
million you cancer cases are diagnosed every year
00:00:26
for this reason several counties have established screening programs
00:00:30
and the standard screening method today is mammography
00:00:34
as you can see from the image it's a very painful procedure
00:00:37
in suppressed has to be compressed between to play tense
00:00:41
and it addition to that the images have limited
00:00:44
contrast and and a high false positive rate
00:00:50
now at the pow share in situ it we have invented a method called grating interferometer e.
00:00:57
it's great thing interferometer to be can in addition to the absorption of the x. really also assess
00:01:04
re fraction at this captain optics really this additional information helps us to
00:01:10
highly improved the contrast and he should details in the images
00:01:16
this invention here now integrating at great x. ray in
00:01:20
a dedicated to press computed the mocha faces and
00:01:24
woman lies prone on a patient table and the rest is
00:01:28
examined in the patient and in the breast opening position
00:01:33
this method is painless and provides us true three
00:01:37
dimensional images at the very high contrasts
00:01:41
at relatively low radiation those lower then today
00:01:49
the method of creating interferometer you has been developed at the power share institute and the e. g.
00:01:54
agents to rake in the group of professor mark was dampened only over the last ten years
00:02:00
all the inventions have been protected by patents and a great x.
00:02:05
ray has negotiated a license agreement with the parser institute
00:02:09
get access to eight of these patents
00:02:14
that that's the next steps we are now developing this prototype
00:02:18
which we want to finish in two years from now
00:02:21
and bring onto the well aligned marketing euro in three and a half years from now
00:02:28
and this is the teen currently working at great x. ray it's my colleague
00:02:33
send young one you said call inventor of eight patents in this field
00:02:38
and has a lot of experience with this grating interferometer e. i myself i martin stopper
00:02:44
i'm a former c. e. o. of p. cube another e. th spinoff company
00:02:49
at this stage we're looking to raise money of two million swiss francs
00:02:54
for the development of the prototype and then in a
00:02:57
later stage we're looking for not the two million
00:03:01
for the certification thank you very much for your attention and supporting critics really
00:03:08
very good thank you to have a question for marking anybody and ah here like they'll let it so you
00:03:20
can read reduce the false positives do you have any
00:03:24
validation for that already quantitative they go by mutation
00:03:30
okay so we have the uh run a study in with mastectomy
00:03:34
is in uh uh so uh you know laps environment
00:03:38
where andy was significantly better the the images are only two d. but uh it
00:03:44
was a double bind to study and the doctors had to rate different the
00:03:49
a day which is a fine to identify the different features and the
00:03:53
images it creating interferometer reversed significantly better than the classic mammography images
00:03:59
right now we're running a study or early next year to
00:04:03
study will be done actually with the power share institute
00:04:07
with the two d. system at the university hospital this will be the first study
00:04:12
done in patients into d. and this information will help us to better
00:04:17
want to five how much we can reduce the false positive like
00:04:21
thank you very much ah ha ha ha ha ha
