Method and system for millimeter wave synthetic aperture radar imaging for superficial implant monitoring

A system comprising:

• a millimeter-wave (mmWave) to scan a body part of a subject comprising one or more orthopedic implants;
• a memory in communication with the one or more hardware processors, wherein the one or more hardware processors are configured to execute programmed instructions stored in the memory to:
• obtain an uncompressed synthetic aperture radar (SAR) complex data from the mmWave radar, wherein the uncompressed SAR complex data comprises a real part and an imaginary part;
• extract a topography information of a predefined region of the body part from the SAR complex data;
• estimate one or more along-track bins associated with the predefined region of the body part where one or more orthopedic implants are comprised, wherein the one or more along-track bins provide a predefined location of the topography information of the body part in a SAR image;
• obtain an SAR amplitude image by taking absolute value of the SAR complex data;
• and
• localize the one or more orthopedic implants in the body part of the subject using the obtained SAR amplitude image and the one or more along-track bins.

One or more non-transitory machine-readable information storage mediums comprising one or more instructions which when executed by one or more hardware processors cause:

• scanning, via a millimeter-wave (mmWave) radar, a body part of a subject comprising one or more orthopedic implants;
• obtaining an uncompressed synthetic aperture radar (SAR) complex data from the mmWave radar, wherein the uncompressed SAR complex data comprises a real part and an imaginary part;
• extracting a topography information of a predefined region of the body part from the SAR complex data;
• estimating one or more along-track bins associated with the predefined region of the body part where one or more orthopedic implants are comprised, wherein the one or more along-track bins provide a predefined location of the topography information of the body part in a SAR image;
• obtaining an SAR amplitude image by taking absolute value of the SAR complex data;
• and
• localizing the one or more orthopedic implants in the body part of the subject using the obtained SAR amplitude image and the one or more along-track bins.
