ABSTRACT
The various Medical images acquired directly from various
instruments are in the AVI format, which reduces the easy control of
image display without conversion to medical image standard, that is the
DICOM format. The purpose of this project is to develop software to
handle online data acquisition from medical equipments like Ultra Sound
machine, control the display rate, convert the AVI image acquired from the
Medical equipment directly to DICOM image with patient’s detail’s got from
the user, freeze the AVI image frame of interest, convert the freezed AVI
frame to Bitmap image, convert this Bitmap image to DICOM image with
patient’s details. This software is highly reliable, efficiently handles
memory and very user friendly.
Medical equipments like Ultra Sound, CT etc… have images at
their output in the AVI file format, which are acquired with the respective
probes. These AVI images acquired are stored. The software captures this
AVI image, displays them frame-by-frame in succession and converts
them to DICOM image with required patient’s details obtained from the
Specialist during conversion. The frame of interest can be freezed and
converted to Bitmap image, which can also be viewed on a separate
window with options to brighten, darken, change the color combination,
invert the image and restore the image. The converted DICOM image can
be viewed on any Standard DICOM viewer. Mostly all the DICOM viewer
will have provision to view the patient’s details entered during conversion.
OBJECTIVE
To help the doctor view a particular frame of interest captured
from a medical equipment which is usually an AVI image and to enable
the doctor to manipulate the frame for correct diagnosis and provide
efficient treatment.
MEDICAL IMAGING
From Ophthalmology and radiology to orthodontics, image
processing touches the medical field in many ways. The ability to visualize
and interactively manipulate three-dimensional objects derived from sets
of two-dimensional MRI and CAT scan (now shortened to CT scan) slices
has changed the way we deal with medicine. MRI stands for nuclear
magnetic resonance imaging.
DISADVANTAGE OF EXISTING SYSTEM
There is no AVI viewer that facilitates the doctors to
manipulate the medical image captured from the equipment. All AVI
viewers available just displays the frames in predetermined time
intervals and time of display of each frame cannot be controls as per
the physicians requirement. Frame at a particular given time can be
displayed but, it wont help the doctor capture the exact frame that is
required to find out the exact defect.
PROPOSED SYSTEM
This system will prove to be user friendly as this captures the
medical AVI image, grabs the required header information, converts them to
DICOM file format and stores it along with the patient’s details, physicians
details, etc… so that any physician can diagnose the patient without any other
further details. Moreover there are many DICOM viewer available with many
image processing provision.
IMAGE PROCESSING:
Images are a vital and integral part of every day life. On
an individual, or person-to-person basis, images are used to reason,
interpret, illustrate, represent, memorize, educate, communicate, evaluate,
navigate, survey, entertain, etc. We do this continuously and almost
entirely without conscious effort. As man builds machines to facilitate his
ever more complex lifestyle, the only reason for NOT providing them with
the ability to exploit or transparently convey such images is a weakness of
available technology.
Applied Image Processing, in its broadest and most literal
interpretation, aims to address the goal of providing practical, reliable and
affordable means to allow machines to cope with images while assisting
man in his general endeavors.
GEOMETRIC TRANSFORMATIONS:
Many times, to combine images taken at different times or by
different sources, we have to translate, rescale, and rotate the images. It
is usually important that the images match spatially. Without proper
registration of images before combination passes, most techniques for
image enhancement will actually degrade the images, losing important or
interesting information.
