Extracorporeal shockwave lithotripsy (ESWL) system and method using in-situ sensing of system and device data and therapeutic/system/device level control

A system for enhancing efficacy for therapeutic or operational outcomes of an extracorporeal shockwave lithotripsy (ESWL) patient therapy, comprising:

• an ESWL system including a plurality of hardware devices configured to produce a focused acoustic shockwave coincident with a patient's kidney stone, wherein the hardware devices comprise an electrical power source configured to charge an energy storage element to provide current to drive a thyratron tube that supplies a high current pulse to an acoustic transducer to originate an acoustic wave inside a focusing element, which in turn generates the focused acoustic shockwave, and an adjustable external AC power supply or an adjustable internal thyratron voltage transformer;
• one or more sensors embedded in-situ with said hardware devices, said sensors configured to sense data including operating parameters and outputs of a plurality of the hardware devices, wherein the one or more sensors include a thyratron heater monitor to measure a thyratron heater voltage and current;
• a system sensor data acquisition and storage assembly configured to capture data from the sensors during operation of the ESWL system to produce the focused acoustic shockwave;
• and
• one or more computer processors configured to process the data to compare the estimated thyratron heater voltage and current to specified values and adjust the external AC power supply or internal thyratron voltage transformer to control the thyratron heater voltage and current to the specified values to provide feedback to control the ESWL system.

• and
• one or more computer processors configured to process the measured light to estimate a present state and statistical behavior of the thyratron tube concerning intensity and spectral content, and assess the thyratron tube's health to adjust a maintenance schedule or a patient therapy to provide feedback to control the ESWL system.
