Apparatus and method for non-invasive, in-vivo, thoracic radio interrogation
First Claim
1. A radio apparatus for non-invasive, in-vivo, thoracic radio interrogation of a subject to collect hemodynamic, respiratory and/or other cardiopulmonary related data from the subject comprising:
- an antenna sized to be positioned proximally to the subject outside the subject;
a radio transmitter operably connected to the antenna and configured to transmit only an unmodulated radio interrogation signal of a predetermined, fixed frequency through the antenna and into the proximally positioned subject; and
a radio receiver operably connected to the antenna and configured to capture through the antenna reflections of the transmitted radio interrogation signal returned from the subject.

Abstract
A radio apparatus and method for non-invasive, thoracic radio interrogation of a subject for the collection of hemodynamic, respiratory and/or other cardiopulmonary related data from the subject includes a antenna positionable proximally to the subject, a radio transmitter transmitting an unmodulated radio interrogation signal of a predetermined fixed frequency at a safe level of about 1 milliwatt or less from the antenna into the subject and a radio receiver capturing through the antenna, reflections of the transmitted radio interrogation signal returned from the subject. A Doppler component of the reflections contains the data that can be extracted from the captured reflections.

13. A method for non-invasive, in-vivo, thoracic radio interrogation of a subject to collect hemodynamic, respiratory and/or other cardiopulmonary related data from the subject comprising the steps of:
-
positioning an antenna proximally to the subject transmitting only an unmodulated radio interrogation signal of a predetermined fixed frequency through the antenna and into the proximately positioned subject; and capturing through the antenna with an operably connected radio receiver reflections of the transmitted radio interrogation signal returned from the subject. - View Dependent Claims (9, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
