Brief Summary
The investigators have developed co-registered transvaginal photoacoustic and ultrasound (US) imaging techniques that allow them to visualize ovarian tumor structure and functional changes simultaneously, which may potentially reveal early tumor angiogenesis development or residual tumors after systemic treatment that is not available by US alone. The ability to detect early angiogenesis changes, as well as tumor morphology changes using a non-invasive imaging modality will greatly enhance the care for patients. The investigators plan to explore these techniques in monitoring cervical cancer treatment response and conduct pilot feasibility studies.

Outcome Measures
Primary Outcomes (1)
Number of participants who complete the imaging protocol
Approximately 18 weeks
Secondary Outcomes (2)
Reduction rate of tumor angiogenesis
3 months after completion of standard of care treatment (approximately 18 weeks)
Charge pattern of blood oxygen saturation
3 months after completion of standard of care treatment (approximately 18 weeks)
Study Arms (1)
Transvaginal probe (Photoacoustic + ultrasound imaging)
EXPERIMENTAL* A transvaginal imaging probe using ultrasound and photoacoustic imaging will be inserted into the vagina and will use different frequencies of lights to create images * This will occur before the first standard of care treatment, mid-treatment, end of treatment, and approximately 3 months after the end of treatment for a total of 4 imaging time points
Interventions
-Four optical wavelengths of 730nm, 780nm, 800 nm, and 830 nm will be used to acquire data
