Handheld imaging devices and related methods

A method for facilitating intra-tissue inspection of a probe at a target region, the method comprising:

• scanning the target region with a longitudinal transducer array to generate a longitudinal scan, and scanning the target region with a transverse transducer array to generate a transverse scan, wherein the longitudinal transducer array and the transverse transducer array are alternatingly oscillated, such that when the longitudinal transducer array is activated to scan the target region, the transverse transducer array is deactivated to cease scanning, and when the transverse transducer array is activated to scan the target region, the longitudinal transducer array is deactivated to cease scanning;
• receiving, from the longitudinal transducer array, data comprising the longitudinal scan of a longitudinal cross-section of the target region;
• receiving, from the transverse transducer array, data comprising the transverse scan of a transverse cross-section of the target region;
• tracking movement of a probe point of the probe based on the longitudinal scan;
• determining a probe point depth of the probe point based on the longitudinal scan;
• generating a transverse cross-section view of the target region based on the transverse scan, the transverse cross-section view having depth coordinates and transverse coordinates, the probe point depth having a corresponding depth coordinate in the transverse cross-section view;
• and
• displaying the transverse cross-section view with a probe point highlight at the depth coordinate of the transverse cross-section view corresponding to the probe point depth of the probe point.
