Official Title

Multimodality 3D Imaging and Wireless Technologies To Enhance Medical Care in Space

Brief Summary

      NASA has outlined the most urgent threats to life and health in manned spaceflight. One of
      the threats is the risk of trauma and acute medical problems. One of the most important
      provisions of acute and chronic medical services in space is the availability of high quality
      diagnostic imaging with the potential for either ground based or onsite interpretation. The
      principle diagnostic imaging modality for space crew use in space will be ultrasound. The aim
      of the study is as follows:

      -To use state of the art 3 dimensional CT scanner to acquire images for segmentation and
      registration supplying a template to judge physiologic or pathologic changes observed in
      space with 3D ultrasound

Detailed Description

In its Bioastronautics Critical Path Roadmap Baseline Document, NASA has outlined the most
urgent threats to life and health in manned spaceflight currently in need of countermeasures
development. This proposal specifically addresses one of four critical risks directly, that
being the risk of trauma and acute medical problems, ID# 43 in the Clinical Capabilities
discipline area. Critical for the provision of acute and chronic medical services in space is
the availability of high quality diagnostic imaging, with either ground-based or autonomous
interpretation. While development of novel sensor technology is actively pursued within the
NSBRI, it is clear that for the foreseeable future, the principal diagnostic imaging modality
for crew use in space will be ultrasound. For the past six years, the Cleveland Clinic has
worked with NASA and NSBRI in a comprehensive program to develop ultrasonographic
capabilities for use in manned space flight. Recent work has focused on enhancement of these
capabilities, including 3D imaging and novel compression and registration techniques for
assessing change over time in ultrasonic images. We now propose to extend these capabilities
in very significant ways, capitalizing on dramatic recent advances in telecommunications and
computerization to better address the critical countermeasures identified. Among the
convergent trends in ultrasound that we seek to capitalize on are the following: most
commonly applied diagnostic imaging test; Miniaturization; file storage; telemedicine;
wireless telemetry; therapeutic use; real-time 3D.

We propose to extend our work with the following Specific Aims:

1. Extension of our longstanding research in 3D ultrasound with a recently developed third
generation machine small enough to fit on the ISS, allowing more comprehensive imaging
to be done with less operator expertise.

2. Utilization of a ultrafast 3D CT scanner to acquire full body 3D images for segmentation
and registration with subsequently acquired 3D ultrasound images, modelling future
missions for ground-based 3D CT or MRI could provide a template to judge physiologic or
pathologic changes observed in space with 3D ultrasound.
