Comparison Table
Elements
vertical specialistSoftware suite for stereotactic radiosurgery and radiotherapy planning with imaging and contouring modules.
Workflow-linked imaging registration and structured plan review keep contour edits and DVH evaluation synchronized.
Elements supports the end-to-end radiotherapy planning workflow from image loading and registration through structure management and plan evaluation using DVH-based constraints. The tool includes dose calculation and optimization workflows that cover common IMRT and VMAT planning patterns, with plan normalization and objective-driven optimization loops. Imaging-to-contours alignment is a core workflow step, and Elements keeps review data organized so radiation oncologists can approve plan geometry and dose distribution details.
A key tradeoff is that Elements tends to be workflow-aligned and structured, so some deeply customized optimization and evaluation styles require extra configuration rather than quick ad hoc changes. Elements fits clinics that need consistent plan review packets and record-and-verify oriented handoff readiness for routine forward planning and inverse planning cases.

Best for: Fits when clinics want consistent, integration-led planning workflow for IMRT and VMAT review cycles.
PRIMO
vertical specialistPRIMO is a Monte Carlo simulation and treatment planning application for radiotherapy dose calculations.
Process-oriented planning configuration that standardizes case steps and reduces planner-to-planner variation.
PRIMO is a radiation treatment planning system designed for clinics that need a repeatable planning workflow with consistent plan outputs. The workflow centers on an optimization and dose calculation process that supports clinical plan approval as part of the planning sequence. It also handles DICOM RT artifacts so teams can exchange structures and plans during routine case processing.
PRIMO places emphasis on process control through configurable planning workflow steps rather than covering every planning style with specialized features. This makes it a strong fit when a clinic wants uniformity across plan types and limits per-case manual adjustments. A tradeoff is that clinics with highly varied planning approaches may need extra configuration work to align PRIMO to every style.
Teams typically use PRIMO when the planning goal is to standardize how optimization is set up and how dose is computed for approval-ready review. For cases that frequently change in protocol details or planning philosophy, additional tuning can be required to preserve output consistency across the variation.
- +DICOM RT plan and structure exchange supports interoperability in mixed systems
- +Workflow configuration helps enforce consistent planning steps across planners
- +Repeatable output reduces variation in routine forward planning cases
- +Extensibility options support integration beyond core UI operations
- –Inverse planning automation depth is limited versus larger TP S ecosystems
- –Monte Carlo dose engine options are not positioned as the default workflow
- –Advanced optimization tuning requires more hands-on configuration work
- –Governance controls like fine-grained RBAC and audit logging need extra attention

MIM Maestro
enterpriseImaging and radiotherapy planning platform for contouring, fusion, review, and adaptive workflow tasks.
Patient-specific plan evaluation that links registration, DVH constraints, and dose display for fast acceptance review.
MIM Maestro is used for dosimetry work centered on image registration, structure management, and quality review before clinician approval. DVH-based constraints checking ties directly to 3D dose display, and multiple plan comparisons can be reviewed against the same anatomical registration. The DICOM RT Plan and DICOM RT Dose import paths enable review of external TPS output while preserving the clinical context of the patient image set. Automation is oriented around repeatable contour and review steps, with tools designed to reduce manual rework across follow-up datasets.
A tradeoff appears in planning depth versus review depth. Optimization controls and machine commissioning style settings are not the same category of capability as a dedicated inverse planning engine, so centers that require optimizer-centric workflows may still rely on a primary TPS for plan generation. Maestro fits best when the clinic wants a strong record and verify style review layer for adaptive replanning inputs, plan QA visualization, and multi-plan acceptance meetings.

How to Choose the Right Radiation Treatment Planning Software
In radiation treatment planning software, the biggest differences show up in how safely teams can reproduce plans over time and how far automation goes in real workflows. We focus on patient safety and control depth: quality assurance workflow, data import/export, automation and API surface, and auditability.
Quality assurance workflow coverage
Why it matters
Quality assurance workflow coverage matters because planning errors can hide until delivery time. If QA steps are incomplete, teams spend extra effort validating basic assumptions each case.
How to check
Run a demo case end-to-end and ask what QA artifacts the system produces before release. Then check whether the workflow supports both document review outputs and technical checks, and whether failures stop plan approval.
DICOM RT import and export handling
Why it matters
DICOM RT import and export handling matters because planning data usually moves between multiple systems. Poor mapping creates silent mismatches that can change structures or doses.
How to check
Import a representative dataset and verify structures and computed dose display correctly on first open. Export an RT plan and RT dose (if offered) and re-import into the system to confirm round-trip consistency.
Automation and API surface depth
Why it matters
Automation and API surface depth matters when physics and dosimetry teams reduce repetitive work. With better extensibility, they can configure recurring steps and reduce manual copy/paste across cases.
How to check
Ask for an example workflow that uses the API or scripting to create contours, set constraints, and generate a plan template. In the demo, try a small repeatable task twice and confirm the configuration stays consistent and versioned.
Plan reproducibility and configuration control
Why it matters
Plan reproducibility and configuration control matters because small parameter changes can shift results. If teams cannot lock settings and track versions, they cannot compare plans across time or sites.
How to check
Create two plans with one controlled change and confirm the system records what changed. Then check whether plans store enough settings to reproduce the same behavior later, including algorithm/configuration choices where applicable.
Adaptive replanning workflow support
Why it matters
Adaptive replanning workflow support matters for teams that iterate during a course of treatment. If the system cannot carry forward structures and dose history cleanly, turnaround time and consistency suffer.
How to check
In a demo, start from an existing plan and then guide an adaptation scenario. Check whether the system preserves prior decisions, supports updating key inputs, and keeps outputs clearly linked to the correct timepoint.
RBAC and audit log traceability
Why it matters
RBAC and audit log traceability matters because planning review involves multiple roles. Without clear permissions and change history, teams struggle to prove who changed what and when.
How to check
In the demo environment, create at least two roles and attempt actions like editing objectives/constraints and releasing a plan. Verify the audit log captures role, action, and affected plan fields in a way you can export for review.
Red flags
- QA workflow produces limited artifacts or does not block release on failed checks.
- Round-trip DICOM RT import/export shifts structures or displayed dose without warnings.
- API automation can’t reproduce the same configuration across repeated cases.
Fit by situation
- If you handle multi-system case transfers, prioritize DICOM RT import and export handling.
- If you need repeatable templates and hands-off planning steps, prioritize automation and API surface depth.
- If your clinic relies on role-based review across time, prioritize RBAC and audit log traceability.
