ノルウェーのAIデータ企業YPAIが、放射線治療の専門家を募集しています。仮名化されたCT・MRI画像のコンツーリング(AI検証用)、完全リモート・時給制の業務委託です。詳細は以下(英語)をご覧ください。英語のプロトコルに従える英語力が必要です。

We need radiation oncologists to contour target volumes on head and neck and brain CT and MRI. Your contours become the expert reference set used to validate a radiotherapy auto-contouring product, so accuracy and consistency matter more than speed. First project: 10 to 40 hours over 2 to 4 weeks, remote, on your own schedule, with further projects for readers who deliver well.

### The work

- Primary work: target volumes (GTV, CTV) and head and neck nodal levels on pseudonymised planning CT, and on MRI where the protocol asks for it.
- Depending on experience: second-reader review of organ-at-risk contours drawn by dosimetrists, and adjudication where two readers disagree, with a logged reason.
- Protocol first; where it is silent, Brouwer 2015 for head and neck OARs, Grégoire for nodal levels, the EPTN atlas for brain. TG-263 structure names.
- Two calibration cases before production. Every case gets independent review, and you see the feedback.
- Cases come in batches from a small, named panel; volume and turnaround are agreed per project.

### Who we are looking for

- Board-certified radiation oncologist, or resident in the final years of training.
- Routine head and neck (with nodal levels) and/or CNS contouring.
- Any treatment planning system or research contouring tool; onboarding in the project platform is provided.
- Written English good enough to follow a protocol and log decisions.

### How the work runs

- Fully remote, flexible hours, as an independent contractor. Open to specialists living in Japan.
- Confidentiality and project-specific data handling requirements apply, and you sign them before any access.
- If your employment contract requires approval for outside work, please arrange it before you accept a project.

Our team reviews applications for this role and contacts selected applicants by email. Applying does not guarantee project work.
