随着最近引入市售的咽部X线透视系统，导管设计应标准化。不同设计的导管由于其设计特征可能产生不同的数据。标准导管设计应使研究者之间的结果具有可比性，并有助于获得可接受的正常值。作者结合多种导管设计的实验室经验进行了综述，并查阅了文献。对于咽部X线透视，建议的标准导管直径应为2 x 4 mm，卵形，长100 cm。导管应以厘米为单位标记前后方向。在最远端传感器之外，应具有轻微延展性，3- 4 cm长，无传感器。固态换能器传感器的数量应为三个或四个，并放置在咽食管段、中下咽和舌根（第四个传感器为食管）。传感器间距应为3 cm，但下咽中部和舌根之间的2 cm除外。由于直径小（患者舒适度），目前首选在颅咽部使用单个环周传感器的单向、同轴、后向传感器。
With the recent introduction of commercially available pharyngeal manofluorography systems, catheter design should be standardized. Catheters of different designs can produce different data because of their design characteristics. A standard catheter design should make results between investigators comparable and facilitate acceptable normal values. The authors' combined laboratory experience with many catheter designs was reviewed and the literature consulted. For pharyngeal manofluorography, the proposed standard catheter should be 2 x 4 mm in diameter, ovoid, and 100 cm long. The catheter should be marked in centimeters with an anterior and posterior orientation. There should be a slightly malleable, 3- to 4-cm length without sensors beyond the most distal sensor. Solid state transducer sensors should be three or four in number and placed in the pharyngoesophageal segment, midhypopharynx, and tongue base (esophagus for fourth sensor). Sensor spacing should be 3 cm, except 2 cm between the midhypopharynx and tongue base. Unidirectional, in-line, posteriorly oriented sensors with the option of a single circumferential sensor in the cricopharyngeus are currently preferred over circumferential sensors because of their small diameter (patient comfort).
