X-ray file conversion to jpg

We have three applications used in dental x-ray and we want them to be uploaded directly to our website( laravel framework) and access it directly from our application after using any of these x-ray applications. These applications have their own unique databases. We need a program like PACS (Picture Archiving and Communication System).
If anyone knows about this system please let me know, so I can arrange a meeting with you and my boss.

Here is sample scenario. Once a patient registered to the website(our app), and the patient need to take a mouth x-ray for example, (the application we will use is depends on what type of x-ray the patient will take depends on the doctor's consultation also.) Lets just that the x-ray is done. Now the x-ray images can be access in the app of that certain x-ray app, now to be able to access it into our app we still need to go to that x-x-ray app to convert it to jpg or png and save it to a folder and then access it from our app via uploading the file. Here is what we want.
We want to automate the process if you get my point. We need something like a Picture Archiving and Communication System. Or we need a program that converts these x-rays file to jpg and a program to upload it or get it from the source send it directly to our app.
I uploaded Sample files of each app with it's application name and the x-ray software will be shared also.
