Final answer:
The question involves the application of physics in echocardiography and MRI scans. It focuses on calculating echo times for ultrasonic measurements and Hall voltage during MRI examinations, both integral components of medical diagnostics.
Step-by-step explanation:
The question pertains to the use of echocardiography and diagnostic ultrasound in medicine, specifically how echo times are used to measure distances within the body and the implications for ultrasound frequency and the resolving power of the diagnostic equipment. Measuring the stroke volume (SV) is one core aspect of echocardiography, using the difference between end-diastolic volume (EDV) and end-systolic volume (ESV). When calculating the difference in echo times for tissues, we consider their distances from the surface, with closer tissues reflecting ultrasound waves more quickly.
In the case provided, to see details as small as 0.100 cm, scanners must discriminate between small time differences corresponding to tissues at depths of 3.50 cm and 3.60 cm. Concerning the period T of the ultrasound, it must be smaller than the resolving time to provide an accurate image. The minimum frequency necessary for such a resolution then determines whether this is within the standard frequency range for diagnostic ultrasounds.
The Hall voltage calculation is another application of physics in medicine. It involves estimating the induced voltage when a conducting pathway, akin to a wire with a specified length, moves within a magnetic field at a certain velocity —a scenario that can occur in Magnetic Resonance Imaging (MRI) procedures.
