Doctor Mode
A toolkit for clinicians to support explanation, counseling, and education in clinic. Everything here is for explanation and guidance only and never generates patient-specific prescriptions.
Note: Doctor Mode is not used to generate prescriptions, doses, or individualized plans. The treatment decision is the treating physician’s responsibility.
Quick disease-site cards
Breast Radiotherapy
Breast radiotherapy is most often given after surgery (lumpectomy or mastectomy) to lower the risk of disease returning in the breast or chest wall.
Open full module →Prostate Radiotherapy
Radiotherapy is a main option for prostate cancer and can be curative on its own or combined with hormone therapy.
Open full module →Head & Neck Radiotherapy
Radiotherapy is used for head and neck tumors (mouth, throat, voice box, salivary glands, and others), usually with curative intent.
Open full module →Brain Radiotherapy
Radiotherapy is used for primary brain tumors or metastases (tumors that spread from elsewhere).
Open full module →Lung Radiotherapy
Radiotherapy is used for lung cancer with curative intent or to control the disease and its symptoms.
Open full module →Pelvic Radiotherapy
Radiotherapy is used for various pelvic tumors (such as rectum, cervix and uterus, bladder, and anal canal).
Open full module →Palliative Radiotherapy
Palliative treatment does not necessarily aim to cure, but to relieve symptoms such as pain, bleeding, or pressure, and to improve your comfort and quality of life.
Open full module →Bone Metastases Radiotherapy
When cancer spreads to the bones it can cause pain or weaken the bone. Radiotherapy is an effective way to relieve this pain.
Open full module →Spine SBRT (Stereotactic Radiotherapy)
Spine stereotactic radiotherapy is a very precise technique used for selected vertebral lesions, to control the tumor and relieve pain.
Open full module →Treatment-intent framing
This frames the explanation of an intent the physician has already decided — it is not a tool to choose or prescribe treatment.

Planning explanation cards
Target volumes (GTV/CTV/PTV)
- GTV: visible disease on imaging.
- CTV: GTV + likely microscopic extension.
- PTV: CTV + setup margin and geometric uncertainty.
- For the patient: "visible tumor, then a reserve zone, then a margin for movement and accuracy."
Fractionation
- Basis: differential repair between tumor and normal tissue.
- For the patient: session count reflects plan and intent, not severity.
- State whether the schedule is conventional or short (hypofractionation) without quoting dose numbers.
Image guidance (IGRT)
- Daily imaging to verify position before the beam.
- For the patient: "we confirm every day that you are in exactly the right place."
- Reassure that verification dose is small and part of precision.
Dose-volume histogram (DVH)
- Summarizes how much dose each volume receives (target and OARs).
- We want the target curve high and the OAR curve to drop early.
- A tool for balancing tumor coverage against organ protection — see the DVH visual.
Organs-at-risk (OAR) cards
Thorax: heart, lung, esophagus
- Lung: pneumonitis / fibrosis — limit irradiated lung volume.
- Heart: late effects — consider breath-hold for left breast.
- Esophagus: acute esophagitis and dysphagia — affects nutrition during treatment.
Pelvis: bladder, rectum, bowel
- Rectum: acute proctitis and late bleeding — emptying protocol and gel spacer.
- Bladder: urinary symptoms — filling protocol improves reproducibility.
- Small bowel: acute diarrhea — prone positioning may help.
Head & neck: salivary glands, swallowing, cord
- Parotids: xerostomia — spare with IMRT.
- Swallowing structures: chronic dysphagia — early rehabilitation.
- Spinal cord: a strict, non-negotiable dose limit.
CNS: hippocampus, optic apparatus, brainstem
- Hippocampus: sparing reduces memory impact in whole-brain treatment.
- Optic nerves/chiasm: dose limit to avoid vision loss.
- Brainstem: strict limit to avoid serious complications.
