[未经美国FDA批准或清除的设备试验] (LEOPARD-IG)
2026年9月11日 更新者:Kevin R. Rogacki, MD、Medical College of Wisconsin
This is a device feasibility study to determine the feasibility of automatically predicting time to treatment readiness using a wearable imaging device (Fullyet) in both healthy volunteers and patients with pelvic malignancies undergoing radiation therapy.
研究概览
详细说明
The purpose of this study is to test an experimental wearable, ultrasound-based device to measure the fullness of the bladder.
In order to protect organs at risk of damage, treatment timing with pelvic radiation depends on a full bladder each day.
Right now, people drink water and guess when their bladders are full.
Each day, CT scans are taken immediately before radiation treatment to look at the size and shape of the bladder and rectum.
Up to 50% of patients are not ready for treatment.
They must return to the waiting area to fill their bladder.
Over a typical course of fractionated radiation therapy, patients require five to six extra scans to make sure that the bladder is ready for treatment.
Delays can cause stress and anxiety for the patient, as well as the administration of unnecessary CT scans resulting in higher radiation exposure.

武器和干预
参与者组/臂 |
干预/治疗 |
|---|---|
|
实验性的:Healthy volunteers
Five healthy volunteers will be enrolled in this study.
|
Healthy volunteers will first have an MRI scan.
Then, they will wear the Fullyet Device.
They will have up to two more MRIs to confirm bladder volume.
|
|
实验性的:Cancer patients
Ten cancer patients will be enrolled into this study.
|
Cancer patients will wear the Fullyet Device.
Real-time data will go to the patient and radiation therapy team.
When the Fullyet Device indicates that the bladder is at optimal size, the radiation oncology team will get the patient.
The patient will then have a CT scan.

The number of events showing feasibility
大体时间:Up to 2 months
|
The feasibility of acquiring and assessing relative bladder volume and morphology will be measured using the Fullyet wearable imaging device and compared to CT (for patients) or MRI (for healthy volunteers).
Specifically, feasibility will be the number of events showing successful data acquisition.
A successful data acquisition event refers to the device's ability to approximate bladder size to that measured on the daily cone beam CT (for patients) or MRI (for health volunteers) to approximately ±30%.
