A system and method enhance the visibility of medical devices shown in internal images. A medical device may be inserted into a patient. Internal images of the patient may then be acquired via various medical imaging techniques. However, the medical device may only be partially visible in the images, if at all. For instance, the images may be acquired with minimal radiation exposure to the patient and/or the medical device may be thin or made of translucent material. Model data may be associated with the geometry or other characteristics of the medical device. The model data may be adapted, such as rotated, resized, bent, or otherwise modified, to form a “best fit” with the medical device as actually shown in the internal images. The adapted model data may be superimposed onto a display of the medical device as shown in the internal images to enhance visibility of the medical device.
