Waveform inversion for Ultrasound Computed Tomography (USCT) is an emerging high-resolution imaging technique for breast cancer screening. Despite its potential, the involved computational burden is challenging. This mainly depends on the total number of wave propagation simulations solved during the inversion procedure. Thus, the computational cost can be reduced by only selecting the...

34. Upper Bound of Accuracy for Self-Calibration of a 3D Ultrasound Tomography System without Ground Truth

A Newton’s method based self-calibration was presented in previous work for a 3D Ultrasound Tomography System (USCT). The method sequentially calibrates a complex USCT system with 2041 transducers based on time-of-flight (TOF) measurements. A direct evaluation of the calibration result was not possible due to unknown ground truth. In this work we present a method to estimate the upper boundary...

Breast cancer has become one of the primary diseases threatening women’s health. Ultrasound computer tomography (USCT) has attracted many researchers’ attention for its potential in early diagnosis of breast cancer. In USCT system, transducer with large number of elements are often be adopted[4-5]. Platform with large number of channels is needed, In this paper, we describes the system design...
