Validation of advanced hybrid SPECT/CT system using dynamic anthropomorphic cardiac phantom.

Objective: Myocardial blood flow (MBF) assessment can provide incremental diagnostic and prognostic information and thus the validation of dynamic SPECT is of high importance. We recently developed a novel cardiac phantom for dynamic SPECT validation and compared its performance against the GE Discovery NM 530c. We now report its use for validation of a new hybrid SPECT/CT System featuring advanced cadmium zinc telluride (CZT) technology in a ring array detector design (StarGuide™, GE HealthCare).

The use of the reds noninvasive lung fluid monitoring system to assess readiness for discharge in patients hospitalized with acute heart failure: A pilot study.

Background: Inadequate decongestion is common in hospitalized heart failure (HF) patients and may contribute to readmissions. Our purpose was to use remote dielectric sensing (ReDS) technology to measure lung congestion at discharge in patients admitted with acute HF and to see if a device-targeted intervention could reduce HF readmission rates.

Methods: We conducted a prospective pilot study of patients admitted with acute decompensated HF randomized to receive standard therapy or ReDS-guided therapy to determine the timing of hospital discharge based on the amount of lung congestion present after diuresis.

A comparative study for chest radiograph image retrieval using binary texture and deep learning classification.

In this work various approaches are investigated for X-ray image retrieval and specifically chest pathology retrieval. Given a query image taken from a data set of 443 images, the objective is to rank images according to similarity. Different features, including binary features, texture features, and deep learning (CNN) features are examined.
