Three Palm Software

What Three Palm Software does

Three Palm Software, Inc. is a privately held medical imaging software company founded in February 2007 in Los Gatos, California, and reincorporated as a California C corporation in April 2008. The company specializes in breast imaging software and operates four core products: WorkstationOne (a multi-modality breast imaging interpretation workstation supporting digital mammography, digital breast tomosynthesis, ultrasound, MR, CT, and nuclear medicine), CadOne (a CAD server for OEMs that detects mass densities and calcification clusters and emits DICOM Mammography CAD SR), MammoViewer (a DICOM CD/DVD viewer bundled with medical disc publishers), and LesionOne (a lesion tracking application framework for monitoring cancer lesions across sequential studies). Three Palm holds FDA 510(k) clearance (K073272), CE marking under EU MDR, ISO 13485:2016 certification from BSI, a Health Canada Medical Device Licence, and a UKCA Declaration of Conformity, and has been granted three US patents covering tomosynthesis CAD algorithms (8,184,890), tomosynthesis-related workstation technology (8,340,387), and mammography workstation UI/workflow including systematic masking (8,803,911). The company was founded by Dr. Patrick Heffernan (CEO/CTO) and Dr. Daoxian (Heidi) Zhang (VP Clinical Affairs/Chief Scientist), both formerly of Kodak Health Imaging after its acquisition of Miramedica.

The technology stack is built on DICOM-compliant imaging with bi-directional PACS, RIS, and reporting system integration; a two-level pre-fetch system; peer-to-peer worklist synchronization; and 10-bit grayscale display acceleration via NVIDIA Quadro, Matrox Xenia Pro, and Barco MXRT controllers. WorkstationOne incorporates Tabar's systematic viewing methodology and supports native DICOM Structured Report generation following the Breast Imaging Reporting template. The product family has released continuously since 2007, with WorkstationOne 1.9.4 shipping in July 2025 featuring expanded CAD/AI vendor coverage. CadOne offers CAD processing throughput of 120-690 cases per hour for a standard 4-view study at 25-100 micron resolution on dual-core CPU. LesionOne provides quantitative measurement toolkits for evaluating and tracking changes in measurable cancer lesions over multiple time points across modalities.

Three Palm operates a B2B software licensing business with three revenue streams: (1) one-time/perpetual site licenses for WorkstationOne sold to hospitals, breast imaging centers, and radiology practices; (2) OEM/embedded licensing for CadOne and MammoViewer integrated into mammography equipment and media publishing systems; and (3) channel/distribution revenue through 80+ partners including exclusive global distributor Metaltronica, exclusive EMEA distributor Dexela, Korea distributor Medi-Future, and US distributor Broadwest. The company sells directly in the US through enterprise field sales and indirectly through partners across North America, Europe, Asia, Middle East/Africa, and LATAM, serving breast imaging radiologists, hospital and imaging center IT, and OEM equipment manufacturers. Cumulative license sales exceeded 400 across 16+ countries. The company maintains offices in Los Gatos and Campbell, California, and reports 1-10 employees.

Core offering

Three Palm Software develops and sells a suite of specialized medical imaging software products for breast cancer screening and diagnosis. The portfolio includes WorkstationOne (a multi-modality breast imaging interpretation workstation), CadOne (a mammography CAD server offered to OEMs), MammoViewer (a DICOM CD/DVD viewer for portable media), and LesionOne (a longitudinal lesion tracking application framework).

Product overview

Three Palm Software develops a suite of leading-edge medical imaging software products for early diagnosis in breast imaging. The product portfolio consists of four distinct software products: WorkstationOne (the core multi-modality breast imaging interpretation workstation), CadOne (a mammography CAD server), MammoViewer (a DICOM CD/DVD viewer for mammography), and LesionOne (a lesion tracking application framework). WorkstationOne is the primary product, serving as the radiologist-facing interpretation workstation that integrates with PACS, RIS, and external CAD/AI systems, while CadOne is an OEM CAD engine that processes mammography images and generates detection reports consumed by WorkstationOne and compatible workstations. MammoViewer extends reach to portable media, and LesionOne provides longitudinal lesion tracking beyond the screening workflow.

Recent moves8 records

Expansion highlights5 records

Broad incumbents

• GE HealthCare: Major medical imaging incumbent selling mammography systems (Senographe), PACS (Centricity), and AI. Competes via full-stack breast imaging offering; relevant as WorkstationOne is integrated to GE CTO format and connects into GE PACS environments.
• Siemens Healthineers: Major medical imaging incumbent with mammography (MAMMOMAT) and syngo PACS/workflow products. Founder Daoxian Zhang previously worked at GE Medical Systems, illustrating the talent flow between the imaging giants and niche software vendors like Three Palm.
• Hologic: Dominant mammography equipment vendor (Dimensions/3Dimensions systems) with bundled Genius AI diagnostics. Both a partner (Genius AI integrated into WorkstationOne) and broad incumbent competing across mammography hardware, software, and AI.
• Sectra: Enterprise imaging IT vendor with PACS and breast imaging PACS solution. Competes in hospital imaging IT and is a comparable for WorkstationOne's enterprise PACS integration footprint.

Direct peers

• Volpara Health Technologies: Breast density and risk assessment AI platform (originally Matakina, integrated into WorkstationOne). Provides complementary breast density software and competes in the mammography analytics workflow.
• iCAD: Direct competitor in mammography CAD with ProFound AI suite for 2D and 3D tomosynthesis. iCAD is integrated into WorkstationOne but also competes by selling its own CAD/server offerings and AI to the same breast imaging customers.
• ScreenPoint Medical: Develops Transpara, an AI decision-support product for 2D mammography and 3D tomosynthesis integrated into WorkstationOne. Competes by offering AI overlays but currently relies on workstations like Three Palm's for delivery.
• Therapixel: MammoScreen 2D/3D mammography AI vendor integrated into WorkstationOne. Direct competitor in AI decision support for breast imaging with FDA-cleared and CE-marked offerings.
• Lunit: Provider of Lunit INSIGHT MG mammography AI integrated into WorkstationOne. Well-funded AI vendor with global distribution; competes at the AI layer and increasingly adds reporting/workflow capabilities adjacent to workstations.

Emerging players

• CureMetrix: AI vendor with cmTriage CAD product integrated into WorkstationOne. Emerging mammography AI company with FDA-cleared triage solution targeting the same clinical decision-support use cases.
