The couch mounted Delta4PT phantom is now used in around 300 centres world-wide for pre-treatment verification of complex radiotherapy plans. The new head mounted Delta4AT allows this verification to continue throughout the patient’s treatment.
In the United Kingdom, the use of in-vivo dosimetry is nationally recommended for the first fraction for all patients, but in most centres it is used for only a few patients.
Delta4 family of products for precise QA from plan to last treatment fraction
Testimonial - Royal Surrey, Guildford
"The Delta4 is easy to use and excellent for both machine QA and patient QA for IMRT and VMAT techniques. ScandiDos provides quick and efficient service for troubleshooting and advice, and also listens to their customers to help improve the software and hardware to make our jobs easier. The Delta4's high sensitivity can detect small errors (less than 2mm) and the software makes it easy to find the cause of the problem. Essential for any QA service for advanced radiotherapy techniques". Sabeena Sidhu, Clinical Scientist
