Intended Use

DCM is a three-dimensional radiotherapy dose engine for radiation dose planning of patients undergoing external beam treatment in the oncology clinic. Based on quality assured radiation therapy input data Dose Calculation Module (DCM) is used to plan radiation treatment with: - Linear accelerators with X-ray energies from 4 to 50MV and electron energies from 6 . to 25 MeV - . Cobalt-60 units DCM will calculate dose for 3D radiotherapy treatment approaches of combined modality plans, asymmetric and non-coplanar fields; total body irradiation; multi-leaf collimators; motorized and dynamic wedges; customized blocking and bolus.

Device Story

DCM 2.0 is a 3D radiotherapy dose engine; functions as a module within the THERAPLAN treatment planning system. Inputs include DICOM objects and control communication protocol data from THERAPLAN. Device calculates radiation dose for external beam treatments; supports combined modality plans, asymmetric/non-coplanar fields, total body irradiation, multi-leaf collimators, motorized/dynamic wedges, and customized blocking/bolus. Used by clinicians in oncology clinics to generate treatment plans; output assists in clinical decision-making for radiation therapy delivery. Benefits include precise dose calculation for complex treatment geometries and expanded capability for electron beam planning.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

3D radiotherapy dose engine. Incorporates Voxel Monte Carlo (VCM++) algorithm for electron dose calculations, supported by an electron Beam Model (EBM). Compatible with linear accelerators (4-50MV X-ray, 6-25 MeV electron) and Cobalt-60 units. Operates as a software module receiving data via DICOM and control communication protocols.

Indications for Use

Indicated for patients undergoing external beam radiation therapy in an oncology clinic setting. Used for planning treatments involving linear accelerators (4-50MV X-ray, 6-25 MeV electron) and Cobalt-60 units.

Regulatory Classification

Identification

A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.

#### 1.7 Description of Dose Calculation Module (DCM):

食

DCM 2.0 is intended for calculations of dose plans, the calculations are based on DICOM objects and other information conveyed by a control communication protocol from the THERAPLAN treatment planning system.

### 1.8 Intended use of DCM:

g

DCM is a three-dimensional radiotherapy dose engine for radiation dose planning of patients undergoing external beam treatment in the oncology clinic.

{1}------------------------------------------------

Ko 20971 20f2

Based on quality assured radiation therapy input data Dose Calculation Module (DCM) is used to plan radiation treatment with:

- Linear accelerators with X-ray energies from 4 to 50MV and electron energies from 6 . to 25 MeV
- . Cobalt-60 units

DCM will calculate dose for 3D radiotherapy treatment approaches of combined modality plans, asymmetric and non-coplanar fields; total body irradiation; multi-leaf collimators; motorized and dynamic wedges; customized blocking and bolus.

Note: This intended use is a direct subset of the Intended Use of the predicate device, DCM with the addition of electron dose calculations for electron beams from 6 to 25 MeV.

#### 1.9 Technological Characteristics

DCM 2.0 has the same technological characteristics as DCM 1.0 and introduces the capability of performing electron calculations using the Voxel Monte Carlo, (VCM++) algorithm, supported by the electron Beam Model, EBM.
