Embodiment Construction

[0051] Depend on figure 1 A schematic illustration of a scanning device 10 according to the invention can be seen. The scanning device has a balloon 12 which consists of a balloon membrane 14 which consists of an elastically extensible material. The balloon body 12 has a balloon connection 16 in a manner known per se. A scan head support 18 extends through the balloon interface, which holds the scan head 20 inside the balloon and guides the scan head securely.

[0052] Mounted on the scanning head 20 are a plurality of scanners, of which two scanners 22 and 24 are shown here. In fact, a plurality of scanners, for example 100, can also be provided, and when the number of scanners is small, these scanners are preferably movably supported on the scanning head 20 .

[0053] The scanner has the task of detecting the entire lumen of the balloon membrane 14 . The balloon film 14 has a reference pattern 26, which in the illustrated embodiment is formed in the form of a grid, which...

Abstract

The invention relates to a recording device (10), comprising a scanning-head carrier (18) for moving the scanning head (20) across a scan zone (42) of a cavity, which scan zone (42) extends around thescanning head (20). A planar or film-like, elastically extensible material extends between the scanning head (20) and the scan zone (42), which material can be pressed against the scan zone (42) in the form of a balloon (12) produced by the application of positive pressure. The scanning-head guide (18) extends through the balloon connection (16) of the balloon (12) to the scanning head (20). In particular, a control device (44) determines the shape of the cavity (40) against which the material rests from the deformation of the material while the positive pressure is applied. A second extraoral scanning head (43) scans deformations during the application of pressure to the film-like material.

Description

technical field [0001] The invention relates to a recording device according to the preamble of claim 1 and a method for operating a recording device according to the preamble of claim 15 . Background technique [0002] It is known per se to arrange a balloon, which can be inflated, around the recording coil for evaluating the measurement signal. This inflation takes place via a balloon interface, through which the interface for the measuring sensor element also passes. [0003] Such a solution is known for the medical field, for example, from DE 42 33 809 A1, but also, for example, from WO 2014 / 145058 A1. This solution allows the protection of sensitive measuring sensor elements and is used, for example, to analyze the ear canal. [0004] In some cases it is desirable to examine the internal structure of the cavities, which are also partially uneven. For this purpose, methods using stereoscopic measurements have been proposed, using scanning heads that are spaced apart f...
