معرفی کلی

TiGRT IVS یا Image Viewing System یک سیستم بازبینی تنظیم بیمار بر روی تخت درمان (Patient Position Verification) و تصویربرداری الکترونیکی پورتال (EPID) دقیق و راحت است. از مهمترین کاربردهای این دستگاه می توان به موارد زیر اشاره کرد:

Patient position verification

Patient tumor tracking and localization

Portal verification and record

Dynamic MLC leaf detection

Dosimetry verification

Exist dose recording

IVS از یک پانل سخت افزاری دیجیتال 8" یا 16" و نرم افزار کنترلی قدرتمند بهره می برد که برای محاسبه بردار اصلاح کننده شش بعدی (3 انتقال، دوران، پیچ و رول) استفاده شده و برای تنظیم موقعیت بیمار در موقعیت از پیش تعیین شده لازم است.

  امکانات ویژه

1. Import of DICOM 3.0/RT patient data sets.
2. The data and images are stored and retrieved from the DICOM server.
3. Generate digital reconstruction radiograph (DRR) in seconds.
4. With necessary CT resolution of 0.8mm slice thickness and 0.6mm pixel size, the correction accuracy of 0.5mm in translation and 0.5° in rotation can be achieved.
5. Support for 2D registration using only one DR image, and 3D registration using two DR images; Display DRR, DR, and overlay image on the same panel.
6. Display correction vector in full screen for distant viewing; Arrange registration and correction both automatically and manually.
7. The IVS software can control several hardware interfaces connected to the Data Acquisition computer.
8. The IVS software can manage several configurations for DICOM files, X-ray flat panel (both KV images and MV images), tube settings (for KV images), treatment geometry, etc.
9. Digital panel based EPID Dosimetry can be used as an efficient tools to replace wet/dry film, dosimetry array detectors, to perform conventional QA, in a 2D/3D fashion.
