MRI Planner

Spectronic Medical AB

MRI Planner creates synthetic CT images for photon external-beam radiation planning from MRI and can generate healthy-structure contours for specified brain, head-and-neck, and pelvic workflows; it is not intended to contour tumors or clinical target volumes.

Evidence status: each field shows source quality, applicability, and review date. Research pending, information not established in reviewed sources, and vendor documentation pending are distinct outcomes.

Implementation

Questions for IT, informatics, and operations

Use these fields to structure a vendor demo, security review, and implementation estimate.

Integration
DICOM MRI, synthetic CT, RTSTRUCT, and planning-system exchange; validate registration, patient identity, geometry, density assignment, dose, and export.
Public source Product family Checked 2026-09-03

Current vendor materials are product-family evidence for K211841; confirm the exact cleared version, enabled options, deployment, and local compatibility.

Deployment and data flow
Release-specific clinical software deployed on a workstation or server within the radiation-oncology network.
Public source Product family Checked 2026-09-03

Current vendor materials are product-family evidence for K211841; confirm the exact cleared version, enabled options, deployment, and local compatibility.

Security and privacy
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-03

Public materials reviewed for this exact release do not establish the complete security posture. Request data-flow, identity, audit, encryption, retention, remote-access, vulnerability-management, backup, and incident-response evidence.

Training and support
Only qualified radiation oncologists, medical physicists, dosimetrists, and radiation therapists should operate or interpret the product. Local onboarding should cover the exact release, supported population, limitations, failure examples, escalation, downtime, and competency documentation.
FDA source Exact FDA submission Checked 2026-09-03
Monitoring and change control
Monitor by exact hardware, software, model, and algorithm version; patient population; anatomy; protocol; operator; input quality; output edits or overrides; failed studies; repeat acquisition or rework; downstream impact; downtime; incidents; recalls; and updates. Track these product-specific limits: Synthetic CT and auto-contours are limited to labeled anatomy and structures and are not tumor or clinical-target-volume delineation; qualified staff must verify images, contours, dose, and plans before treatment.

Later product-family features are not evidence that this cleared release includes them.

Interoperability acceptance

DICOM MRI, synthetic CT, RTSTRUCT, and planning-system exchange; validate registration, patient identity, geometry, density assignment, dose, and export.

product family · checked 2026-09-03

Test representative identifiers, orientation, geometry, measurements, units, routing, failure handling, and round trips locally. Vendor statements are current product-family context; confirm the exact cleared release and installed options.

Clinical acceptance

Use a signed local test set for the supported population and workflow. Include common and difficult cases, exclusions, acquisition variation, failed or low-quality inputs, reviewer overrides, and downstream effects. Synthetic CT and auto-contours are limited to labeled anatomy and structures and are not tumor or clinical-target-volume delineation; qualified staff must verify images, contours, dose, and plans before treatment.

No exact-product price was found in the reviewed public material; vendor productivity claims are scenario inputs, not guaranteed local savings.

Lifecycle monitoring

Monitor by exact hardware, software, model, and algorithm version; patient population; anatomy; protocol; operator; input quality; output edits or overrides; failed studies; repeat acquisition or rework; downstream impact; downtime; incidents; recalls; and updates. Track these product-specific limits: Synthetic CT and auto-contours are limited to labeled anatomy and structures and are not tumor or clinical-target-volume delineation; qualified staff must verify images, contours, dose, and plans before treatment.

Recovered from the prior exact-submission extraction and normalized under the current provenance rules. Exact FDA decision materials were reviewed for identity, indication, users, workflow, limitations, and submitted performance. Current vendor material is labeled product-family context where it does not establish the exact release. PubMed and ClinicalTrials.gov results are retained as candidate evidence with version applicability pending; CMS reimbursement context and exact-identifier openFDA postmarket results were also checked. Pricing, final security architecture, contracted services, enabled options, and local interoperability remain organization-specific evidence. Automated exact-name discovery found 6 PubMed and 0 ClinicalTrials.gov candidate records. Candidates require human product and version matching; zero candidates is not evidence that no studies exist. Native FDA recall identifiers produced 0 postmarket candidate records; 0 have been reviewed (0 published, 0 rejected) and 0 remain unreviewed.

Candidate leads remain unpublished until a human confirms the exact product and tested version.
