Workflow navigation pilot
Workflow role has not yet been reviewed for this navigation pilot.
A tag identifies a documented role; it does not establish compatibility or local acceptance. Methods and sources
- What does this software do?Authorized purpose: Process, review, analyze, communicate, and exchange multidimensional CT or MR images, including preliminary segmentation of normal anatomy, for preoperative surgical planning and intraoperative display; healthcare professionals make all final patient-management decisions. Machine-learning algorithms are for adults aged 22 years and older, while images for patients under 22 or of unknown age are generated without machine learning.
- Which images or clinical context are in scope?Modality: CT/CTA; MRI Anatomy or clinical context: Multi-region normal anatomy represented in CT or MR images; validated examples include prostate, bladder, neurovascular bundles, kidney, artery, and vein Input: Existing multidimensional digital images acquired from CT or MR imaging devices; patient age determines whether machine-learning algorithms are used, with no machine learning for patients under 22 or of unknown age.
- Who uses it?Intended users: Healthcare professionals; company personnel generate the 3D images in the described service workflow
- What does the software produce?Output: Three-dimensional images viewable through compatible mobile and desktop viewer applications, external displays, or compatible off-the-shelf VR headsets; users can manipulate the images, selectively show or hide anatomical structures, view measurements of or between structures, and review preliminary segmentations of normal anatomy.
- What is its most important limitation?Key limitation: Machine-learning algorithms are limited to adults aged 22 years and older; under-22 or unknown-age 3D images are generated without machine learning. Segmentations are preliminary and limited to normal anatomy, and the clinician retains final management responsibility. The device is not intended to provide semi-automated segmentation of abnormal anatomy or integrate with surgical instruments for real-time guidance/navigation; specific current interfaces and deployment are not established.
Clinical takeaway. Clinical role: Process, review, analyze, communicate, and exchange multidimensional CT or MR images, including preliminary segmentation of normal anatomy, for preoperative surgical planning and intraoperative display; healthcare professionals make all final patient-management decisions. Machine-learning algorithms are for adults aged 22 years and older, while images for patients under 22 or of unknown age are generated without machine learning.
Evidence takeaway. Evidence from the reviewed source record: FDA K233568 reports software verification and validation using 141 actual CT or MR imaging studies, with training and testing kept independent at the scanning-institution level. Four machine-learning models were compared with medical-professional segmentations: prostate DSC 0.87, bladder DSC 0.90, neurovascular-bundle HD-95 7.8 mm, kidney DSC 0.89 for CT abdomen and 0.87 for MR abdomen, artery DSC 0.87 for CT abdomen, 0.83 for MR abdomen, and 0.85 for CT chest, and vein DSC 0.86 for CT abdomen, 0.81 for MR abdomen, and 0.81 for CT chest. Volume, diameter, and two-point-distance measurements were verified within a mean difference of plus or minus 10%.
- Purpose
- Process, review, analyze, communicate, and exchange multidimensional CT or MR images, including preliminary segmentation of normal anatomy, for preoperative surgical planning and intraoperative display; healthcare professionals make all final patient-management decisions. Machine-learning algorithms are for adults aged 22 years and older, while images for patients under 22 or of unknown age are generated without machine learning.
- Workflow role
- 3D CT/MR image generation and interactive review for preoperative planning and intraoperative display, with preliminary normal-anatomy segmentation and measurement support; the device is not integrated with surgical instruments for real-time guidance or navigation.
- Required input
- Existing multidimensional digital images acquired from CT or MR imaging devices; patient age determines whether machine-learning algorithms are used, with no machine learning for patients under 22 or of unknown age.
- Output and clinician action
- Three-dimensional images viewable through compatible mobile and desktop viewer applications, external displays, or compatible off-the-shelf VR headsets; users can manipulate the images, selectively show or hide anatomical structures, view measurements of or between structures, and review preliminary segmentations of normal anatomy.
- Care setting
- Healthcare facilities such as hospitals and clinics; machine-learning use is limited to adult patients aged 22 years and older
- Intended users
- Healthcare professionals; company personnel generate the 3D images in the described service workflow
- Limitations
- Machine-learning algorithms are limited to adults aged 22 years and older; under-22 or unknown-age 3D images are generated without machine learning. Segmentations are preliminary and limited to normal anatomy, and the clinician retains final management responsibility. The device is not intended to provide semi-automated segmentation of abnormal anatomy or integrate with surgical instruments for real-time guidance/navigation; specific current interfaces and deployment are not established.
- Evidence summary
- FDA K233568 reports software verification and validation using 141 actual CT or MR imaging studies, with training and testing kept independent at the scanning-institution level. Four machine-learning models were compared with medical-professional segmentations: prostate DSC 0.87, bladder DSC 0.90, neurovascular-bundle HD-95 7.8 mm, kidney DSC 0.89 for CT abdomen and 0.87 for MR abdomen, artery DSC 0.87 for CT abdomen, 0.83 for MR abdomen, and 0.85 for CT chest, and vein DSC 0.86 for CT abdomen, 0.81 for MR abdomen, and 0.81 for CT chest. Volume, diameter, and two-point-distance measurements were verified within a mean difference of plus or minus 10%.
