    How to get the perfect X-ray for you

    Perfect X-rays are in the eye of the beholder.

    X-rays can be evaluated much like fine art: Beauty is in the eye of the beholder. Just about everyone can agree on what a masterpiece of artwork is and what it looks like, yet everyone will still have different pieces by different artists which are their true favorites.

    Just as with artwork, most doctors can all agree on what a good X-ray is. Also like artwork, most have personal preferences as to what their favorite is. The different reasons that doctors state that they prefer one image over another are generally items like sharpness (not sharp enough or too sharp) and brightness (too light or too dark). There are usually tools in the software that comes with the sensor which allows the provider to make adjustments after the image has been captured, but no one wants to manipulate images all the time just so they can see what they need to see.

    Your sensor

    For your sensor, you want to get a good, high-end sensor for a decent price. The high-end sensors can be differentiated from the lower-end sensors by the image they produce (the resolution of that image especially) and how well the manufacturer stands behind them.

    The images that the sensors produce need to look like good, diagnostic images. The actual resolution of the resulting image needs to be a >20 line pair measurement (LPM) as well. If you hear a number for the resolution of the sensor’s image which is, say higher than 30, then the representative is telling you the theoretical LPM.

    The actual LPM is what you can actually see with your eyes. This is the real resolution of the sensor’s images. This is the number you want to pay attention to when looking to see the quality of the sensor and the resolution of the raw image that it produces.  

    The theoretical LPM is a simple calculation made with the pixel size of the sensors module. It is a theoretical number and not real. The theoretical number would apply if it took into account things like the resistance of electricity when it travels through a copper wire.  But unfortunately, it does not consider many of the physical elements that are part of the reality of how your digital X-ray image is produced.  And since it doesn’t take into account reality, the theoretical number is just that: Theoretical.

    DentiMax has many tools where practitioners can “dial in” the image so that they look like what you want them to look like right off the bat. These tools include a high-quality sensor with an amazingly great raw image, with an actual LPM of >20. 

    A raw image is the initial, unmodified image that any digital sensor produces. Most sensor manufacturers apply some type of enhancements to the initial image so that it doesn’t appear too blurry or underexposed. You can consider the raw image your starting point. If you take a picture with your cell phone or a digital camera, that initial image would be the raw image. If that image is pixelated for example, there is nothing you can do to “un-pixelate” that image. You would need to take that picture at a higher resolution in order to remove the pixilation.

    DentiMax has pre-set “default” settings so that when you take the first X-ray, it may be just what you’re looking for. If it is not however, you can spend a few minutes remotely with one of the DentiMax support techs darkening or lightening the image, or adding or removing some of the sharpness in the image, so that you get the final result that is just what you are looking for.
