Digital Breakthrough For Faster Diagnosis of Acute Appendicitis

With the aid of technology such as using mobile devices for immediate diagnostic process of medical procedures will tremendously save many lives. Medical imaging plays an important role in the medical field. Radiologists must evaluate and interpret complex analyses of images the soonest possible time and correctly.

Last November 2009 annual meeting of The Radiological Society of North America (RSNA), they presented the results of their study of the use of iPhone mobile devices to scan CT scan images with a viewing software installed in the device to diagnose acute appendicitis. The study of 25 patients using the mobile devices were correctly diagnosed resulting to 99% accuracy.

According to Dr. Asim F. Choudhri, the study lead author and a physician in the division of neuroradiology at Johns Hopkins University, “ this new technology can expedite diagnosis, and therefore treatment”. The mobile devices can diagnose even in remote areas or wherever the patient is located, and can be transmitted immediately for physician’s evaluation prior to surgery.

The OsiriX Software

The iPhone G3 with OsiriX Mobile Imaging Viewer Sotware. A free open source software for multimodal and multidimensional visualization of images.

OsiriX software is developed and maintained by Pixmeo SARL, a company based in Geneva Switzerland. The software were created by former UCLA Radiologists, Antoine Rosset M.D. and Dr. Osman Ratib.

OsiriX produces high resolution images with the capability of advanced imaging manipulation aside from regular zoom, pan,adjusting contrast, and brightness of the images. It is at the same time a DICOM PACS workstation for imaging and an image processing software for medical research (radiology and nuclear imaging), functional imaging, 3D imaging, confocal microscopy and molecular imaging.

THE IMPACT OF DIGITAL TECHNOLOGY IN PHOTOGRAPHY

Digital Technology is making its presence felt not only in the
printing industry but more imminent in the field of photography.
Digital photography has taken photographing into a realm of
infinite possibilities. Digital technology has also offered
great diversity when it comes to colors of pictures that were
not possible with the use of traditional photographing
machinery.

Digital technology has also paved the way for express
photography developing which only requires a minimum of 3
minutes to process pictures. This express picture development is
great for rush picture requirements like personal id pictures as
well as rush visa and passport photos. The best-suited camera
used for express development is a digital camera.

The process of express development starts with the taking or the
capturing of an image, which is a multi-process since it
includes image display, as well as image printing by means of a
computer and appropriate printer equipment. However, like any
technology the digital technology is not without flaws, the use
of an incompatible printer may have an adverse effect on the
quality of the developed picture.

In terms of the digital camera to be use, it is important to
correctly choose the camera’s resolution in order to produce
high quality photographs. For passport and visa photos a digital
camera with one mega-pixel resolution is the best choice. Such
types of cameras also have automatic features that are designed
to control the numerous photographic qualities involved in the
process of taking pictures. Nevertheless, the photographer’s
sensitivity when it comes to his or her subject must still exist
since the automatic control of the digital camera won’t be able
to choose from among the subject’s facial expression which is
best to capture or decides on the clothing that would best
reveal the subject’s features.

Camera-to-computer interface are well suited for those
photography activities that require the use of an external
memory card. The transferring of data is also much faster and
offers confirmation of the storage of quality images stored in
the computer. Likewise, it provides a room for retakes and the
images are easily stored in the computer, which is a good thing
since it will be much easier to choose from among the taken
images the one that really stands out.

The computer also plays an important role in digital photography
since it helps in storing and displaying of digital images taken
with the digital camera. The computer also enables for the
printing of the images in various digital printers. And since
digital photography makes use of high-resolution images it is
vital that the computer should have a sufficient memory space as
well as ample storage capacities. Likewise, a computer should
also have a high-speed interface to the camera and printer and a
speedy but reliable CPU in order to provide efficient image
processing.

Digital Art – Is it Really Art?

Most people think art has to involve a brush, paint and a canvas. But today there are so many more forms of art. Practices that utilize digital technology for a range of artistic works are called Digital Art. Other names for this are new media art, computer art and multimedia art. This trend all began in the 70s with the use of personal computers for artistic creations.

This new media art has transformed traditional activities of painting, drawing and sculpture. To put it simply, a digital artist is anyone who uses the computer to enhance, embellish or create his or her art. Digital art is a contemporary art term used to create prints or other digital media.

Although I received my degree in 2-D Art, I also consider myself a digital artist. I have many oil paintings, watercolor, pastels, and drawings, but I truly enjoy the new ability to create art on the computer. In the past I have presented some of my digital creations to galleries, they said that people are slow to consider it as “art”.

If you saw the movie, A Christmas Carol with Jim Carrey, you will witness the 3-D effects of digital art, which produced the special effects. Mainstream media also extensively uses the techniques of digital art. As it took several years for acceptance of electronically produced music over the past three decades, a general acceptance of the value of digital art will eventually come.

Personally, I can draw a picture, scan it into the computer and then color it or put special filters onto it to create a unique masterpiece. Some critics argue that a computer program is the one that made the art, but I would like to submit that the artist is the one who decides when it has actually created a work of art, rather than the computer. I know this is still quite a controversial subject. Some digital artists can create a masterpiece created in a similar fashion to a non-digital painting on their computer, actually using digital brushes and digital paints and then printing it on canvas. Some people cannot tell the difference.

It is interesting that digital photography and digital printing is now an acceptable medium of creation and presentation by major museums and galleries. Some museums have begun to accept digital art printed on canvas. Perhaps one reason why the art community finds it difficult to accept digital art is the erroneous perception digital prints that can be reproduced endlessly. To appease the masses, some artists erase the image file after the first print so it is truly a unique artwork.

There are many different kinds of digital art.

* Algorithmic art – generated by an algorithm or arithmetic

* Generative art – many similarities with systems found in various areas of science

* Art software – Corel Painter, ArtRage, Studio Artist, ArtWeaver (free for Windows) http://www.artweaver.de/

* Computer art http://moca.virtual.museum/

* Cyberarts – produced through a process, any one of whose steps was influenced by such software or hardware

* Electronic art – makes use of electronic media or, more broadly, refers to technology and/or electronic media – video games

* Evolutionary art or Dynamic Painting – exploits the process of evolution to create an artwork which continually changes according to an evolutionary algorithm – fractals – screensavers

* Fractal art – created by calculating fractal objects and representing the calculation results as still images

* Video art – relies on moving pictures and comprises video and/or audio data

* Digital illustration and painting – use of digital tools to produce images under the direct manipulation of the artist, usually through a pointing device such as a tablet or a mouse

* Machinima – the use of real-time three-dimensional (3-D) graphics rendering engines to generate computer animation

* Digital photography – a form of photography that uses digital technology to make images of subjects

* Movie special effects – The illusions used in the film, television, theater, or entertainment industries to simulate the imagined events in a story are traditionally called special effects

* Photo manipulation – application of image editing techniques to photographs in order to create an illusion or deception through analog or digital means (Photoshop and many more)

There are plenty more but, I think you get the idea.
