Conclusion:

This new double-layer arc-shaped ionization chamber matrix performs well in terms of dosimetric properties. Compared with Arccheck, it performs equally well in the dose verification results of IMRT, VMAT, SBRT, and TOMO plans. Both have their own characteristics in three-dimensional dose verification.
