Everyday, we see new cases in our medical imaging activity.

Some are easy to diagnose, others are difficult and we hesitate in getting diagnosis.

In that situation, you can shoot the images on your computer’s screen and send it with MCA.

Instantly thousands of radiologists connected on the web receive notification on their mobile devices with your

medical imaging case.

They can quickly reply by a suggestion of diagnosis in reply to your tweet.

MCA allows this interactive exchange between radiologists worldwide.

Project - Sparkler

Posted by Georgi Christov on June 4, 2014 at 10:50 AM Comments comments (0)

Sparkler is one of my first Android apps in the Play Store. Basically it's an app that allows you to cut the device screen with your fingers. It simulates metal being cut by animating sparks flying around and showing heat trails. Here's the Play Store description:

Sparkler is a fun new app that allows you to cut through metal with your fingers. Turn you device into a piece of metal and cut through it as if you were using a metal grinder. The included sound and vibration effects make the experience even more realistic. Furthermore, you can select different backgrounds or choose your own image. Also, you can make the background transparent and cut the device screen itself.


Application features:

 * cut through metal using your fingers;

 * realistic sound and vibration effects;

 * multi-finger support;

 * change background with picture or one of the built-in metal backgrounds;

 * remove the background and cut the actual device screen;

 * particle physics makes the gravity of the sparks to depend on the current device angle;

 * configure the app's effects for slower devices.

Newest update and new look

Posted by Georgi Christov on June 1, 2014 at 1:45 AM Comments comments (0)

The website has a new look which should hopefully make it easier to navigate and find things.

First of all, since now I've moved into the mobile software development field, I have created separate pages just for that where I will be posting what I'm working on at the moment and a few tutorials now and then. You can find the new pages under the Programming section. I have also moved the Java/Python stuff into their own section also under Programming.

In addition to the new site organization, I've made some changes to the blog format - there are only three categories now and I will post updates on the apps I'm working on there instead of at the home page. These updates will also be followed by screenshots in the Photos/Videos section again under Programming.

Finally, I have decided to keep all downloadable programs in one place - under the Downloads tab in the menu. Unfortunately, I won't be able to post the mobile apps for download here but I will make sure to include links to the Play/App Stores for the ones that are uploaded there.

Removed Source Code page

Posted by Georgi Christov on July 6, 2011 at 2:00 AM Comments comments (1)

I have decided to remove the source code page from the website since I do not have time to upload every single class that I create for my programs, Most of them are separated into packages and it is getting hard to organize them here as well. However, I am including the source code for each program in the program itself so if anybody is interested you can view the source while using the them.

If you can't find what you are looking for in the source, or if I've missed it, fell free to send me a message and I will send you the scripts.

I upgraded my computer and I am running Windows 7 now. It looks pretty good so far. All of my programs are running as they should and I'm still testing the operating system. Also I posted two more programs in the Software page of the site and I am working on 2 more so I'll be posting them soon as well.
