The number one priority for you choosing a doctor is most definately not the version or brand of technology one uses to get a clear idea of what you are seeking. Any technology that shows you a reasonable expectation of outcome is satisfactory. In fact, while this is a legitimate question from you, many companies "plant" questions like this to promote their products. You may have read this in a review or promotion but the far and away the most important priority for you is to find a surgeon has the skill, experience and artistic ability to achieve an excellent
rhinoplasty result for you. Remember the general rule is that in any area of professional endeavor the service provider will not reach their maximum potential until they have spend 10,000 hours doing the task. This must be weighed against the loss of reflexes and skills beyond certain ages. This makes the experience "sweet spot" a surgeon that does between 2 and 10
rhinoplasty operations per week, is still doing this level and actively participates in education and personal professional development.
I suggest you ask these questions first and then if the surgeon meets these criteria, you can ask which of the many very capable imaging programs he or she uses to demonstrate what you would look like after surgery. A surgeon or artist could put you nose on your shoulder on a computer, that doesn't mean a surgeon could achieve that practically. Imaging is a communication tool and an excellent one, but that is all image morphing is, a communication tool.
