Callisto DataHub | Radiology & Pathology Image Data Platform for AI & Clinical Research from Japan

The central hub to buy medical images and clinical data

Callisto provides high-quality, annotated radiological/pathological scans and clinical/molecular data collected from Japanese hospitals/clinics

1. Higher AI performance

We offer millions of high-quality, (annotated) scans—both radiological and pathological—along with clinical and molecular data to boost your AI model’s accuracy, reliability, and functionality. Our datasets, collected from Japanese hospitals/clinics, are particularly ideal for R&D targeting Japan or Asian demographics. Longitudinal data for pharma and life sciences are also available.

Radiological and pathological scans

Radiological scans (X-ray, CT, MRI, mammography, PET, etc.), ultrasound scans, and pathology scans (WSI).

Annotations

Disease segmentations and radiology/pathology reports, annotated and verified by expert radiologists/pathologists. Lung field segmentations are also available. Note: Annotations are generally available only for major diseases.

Clinical information

Age, sex, height, weight, medical history/family history, surgical history, main complaint, major symptoms/progress, nursing observation record, referring department, diagnosis, etc. Molecular diagnostic results may be available, such as ER, PgR, HER2 positive/negative in the case of breast cancer.

2. Shorter R&D cycle

Our datasets, ethically-reviewed, de-identified, and meticulously curated, are ready-to-use for your R&D in medical AI, drug discovery AI, and clinical research. We can provide dataset samples, dataset customization, and data-related consulting services, including medical feedback, customized AI development, and regulatory support for entering the Japanese medical device market.

No ethical review required

ethically sourced and prepared for secondary use

Anonymized

Rigorously de-identified to ensure legal compliance, safeguarding you from compliance risk.

Carefully curated

Data unsuitable for medical AI, such as cases with complications or excessive noise, are excluded. Our comprehensive standardization of images, clinical data, molecular data, and annotations minimizes additional pre-processing and verification.

3. Lower R&D cost

You do not need to heavily invest in collecting, selecting, annotating, and pre-processing various medical data by yourself. Our datasets are versatile and ready for use across a wide range of R&D applications, such as medical AI, drug discovery AI, and clinical research.

Medical AI

Examples: Image diagnosis, automatic contour extraction, and dose distribution creation.

Drug discovery AI

Examples: Drug screening, biomarker discovery, and therapeutic target identification.

Clinical research

Examples: Clinical trial design, drug toxicity/effectiveness evaluation, and histopathological assessment.

To celebrate DataHub's launch, we are offering a free lung cancer CT dataset (152 cases) with lesion and lung segmentations. Annotations have been added to a public dataset, and commercial use is permitted.

Additionally, for DataHub's 2nd anniversary, we are offering a free chest X-ray dataset of suspected lung cancer (50 cases) with lesion bounding boxes, and a free prostate cancer MRI dataset (PI-RADS 4 and 5, 50 cases) with lesion segmentations. Both are Japanese datasets available for commercial use.
