INNOVATION IN ROTATIONAL PANORAMIC RADIOGRAPHIC UNIT BY FAST SCANNING.

一般情况下，旋转式全景无线电造影的曝光时间为12至20秒。在一些儿童中，被处理的病人和年长的病人中，旋转式全景广播术可能是对立的;这样的案例包括Spastics、Hiccups的病人，以及那些在很长一段时间内仍有困难的人。还有一些病人感到害怕，当他们面对着沉重的电影持有人在他们的脸上。哇，这个全嘴放射学调查在这些患者的管理中扮演了一个关键角色。我们已经开发了一个快速扫描的旋转全景无线电单元，以更长的患者-电影距离为目标，但在曝光后较少的不舒适。单元的基本设计1。暴露时间比5秒少。来源-病人-电影的距离几乎是在实践中的。The emergency stop Mechanism is neededed.Specifications of the unitExposure time... 2.5/1.3秒（双/单）旋转时间... 3.0/1.5秒（双/单）源电影距离........ 725 mm2 slit width.. 5 mmPositioning of the patient... seated （or standing）紧急停止机制... sensor on the film holderScreen/film...

Generally the exposure time of rotational panoramic radiography varies from 12 to 20 seconds. In some of the children, the handicapped and the elderly patients, the rotational panoramic radiography may be contraindicated ; such cases include spastics, patients with hiccups, and those who have difficulty in remaining still during a long exposure time. And some of the patients feel fear when faced with the heavy-looking film holder surrounding their face. However, this full mouth radiographic survey plays a key role in management of these patients. We have developed a fast scanning rotational panoramic radiographic unit with longer patient-film distance aimed at less discomfort for these patients during the exposure.Basic design of the unit1. The exposure time is less than 5 seconds2. The source-patient-film distance is utmost in the practice.3. The emergency stop mechanism is needed.Specifications of the unitExposure time ..........................2.5/1.3 seconds (bilateral/unilateral)Rotation time ...........................3.0/1.5 seconds (bilateral/unilateral)Source-film distance ....................................................725mm2nd slit width ............................................................5mmPositioning of the patient ................................seated (or standing)Emergency stop mechanism .............................sensor on the film holderScreen/film .................................................HR-12/S・HR-A(Fuji)Manufactured by ............................................Asahi roentgen Ind.Distributed by .............................................Asahi roentgen Ind.We have developed a fast scanning rotational panoramic radiographic unit. It consideration of the radiographic examination of the patients who have difficulty in remaining still during a longer exposure, this unit is expected to bring us quality improvement in the patient management.
