Image Processing Application
This Seminar Topic deals with the followingABSTRACT
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.
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.
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.
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.
Steps To Control Image
- Capture the image from an medical equipment which will normally be in AVI (Audio/Video Interleaved) format.
- Analyze the header details of the AVI image.
- Copy the required header details into the DICOM header format.
- If the length of the header is greater than zero it is considered to be valid.
- Find the start of frame in the AVI file, check for its length, if data is valid copy the frame into DICOM file else skip the frame.
- View the DICOM file in appropriate DICOM viewer.
