Next ideas in Ultrasound probe techonology? Here you are:

1. Wireless charging for wireless probes. Just put them in place and they will be charged when not in use.
2. 3 Axis IMU orientation, gyroscope and accelerometer. Just a few $$$'s hardware investment needed. a. Would help with 3D Orientation tagging of images. b. Stitching and volume rendering of panoramic and volume acquisition images. c. Measuring hand made movement and pressure with elastography . d. Biopsy guidance. e. Cheap hardware, but needs work on software side. (MPU-6050 shown) 

Current methods of elastography include automated pressure waves generated with piezoelectric effect and hand made pressure waves which are unquantified. Sensing / Sending the acceleration info aquired from transducer will help quantification of pressure. Small pressure sensors on transducers will help even more.

Itoh elasticity

Itoh et al. classification of the breast lesions differentiate them into 5 categories according to elasticity  pattern.

• A score of 1 indicate equivalent strain throughout the lesion 
• a score of 2 indicate strain in most of the lesion with some areas of no strain (a mosaic pattern of colors); 
• a score of 3 indicate no strain in the central part of the lesion (only the central part of the lesion is colored red); 
• a score of 4 indicate no strain throughout the lesion (the entire lesion is red)
• a score of 5 indicate no strain throughout the lesion or the surrounding area (the entire lesion and its surrounding area are colored red)
