"treatment verification" is a correct and usable phrase in written English.
It refers to the process of verifying or confirming the effectiveness or validity of a particular treatment or therapy. This phrase can be used in various contexts, such as in a medical setting, research studies, or even in everyday conversation. Example: After undergoing months of treatment for her illness, Jane's doctor ordered a series of tests for treatment verification to ensure that her condition was improving.
For decades, film was used as a powerful two-dimensional (2D) dosimetry tool for radiotherapy treatment verification and quality assurance.
Treatment verification entailed use of a posterior-anterior (PA) portal film and placement of radiopaque wire on the inferior border of the cranial field.
However, RT planning, delivery, treatment verification and quality assurance (QA) have evolved significantly over the last 15 years and clinical trial protocols must reflect these developments.
The vast majority of the centres perform at least weekly treatment verification and half have access to individual in vivo dosimetry.
The improvement of the treatment has lead to the need of Quality Assurance (QA) devices to detect malfunctioning or human mistakes during the planning phase and treatment verification.
Recent advances in real-time dosimetry and related developments of QA, QC and in vivo dosimetry (IVD) systems have offered new possibilities for effective independent treatment verification, and thus for improving the patient safety.
Radiographer-led assessment of treatment verifications has enabled a UK national multi-centre trial of conformal prostate radiotherapy to be accomplished with acceptably high standards of accuracy and reproducibility.
The introduction of highly conformal techniques has increased the need for pre-treatment verification imaging to confirm accurate positioning of the patient.
In addition to these QA programs of the separate components required for a patient treatment, additional pre-treatment verification checks for individual patients are often performed using, for instance, independent dose or monitor unit (MU) calculation programs, and various QA devices such as ionization chamber and diode arrays.
Treatment geometry verification is based on robotic in-room imaging acquisitions, allowing for 2D/3D registration from double planar kV-images or 3D/3D alignment from cone beam image reconstruction.
The improvement in the therapeutic line includes: application of the four-dimensional computer tomography (4DCT), taking advantage of positron emission tomography (PET-CT), designing of new computational algorithms, allowing more precise irradiation planning, development of treatment precision verification systems and introducing IMRT techniques in chest radiotherapy.
