PSMA-Targeted Radiotherapy Extends Survival

Cancer Discovery, 2021
Abstract A drug that delivers radioactive isotopes to cells expressing prostate-specific membrane antigen (PSMA) prolonged the lives of men with metastatic castrate-resistant prostate cancer, researchers reported at the 2021 American Society of Clinical Oncology Annual Meeting.

Histogram-PMHT for extended targets and target groups in images

IEEE Transactions on Aerospace and Electronic Systems, 2014
This article deals with the integration of random matrices into the Histogram Probabilistic Multi-Hypothesis Tracker (H-PMHT), a parametric track-before-detect method that locates targets in imagery by fitting a mixture of probability densities. The random matrices are used to describe the unknown physical extent of targets in the sensor image, a ...

Data Association for Tracking Extended Targets

MILCOM 2019 - 2019 IEEE Military Communications Conference (MILCOM), 2019
The sum-product algorithm for data association (SPADA) provides a highly effective, efficient, and scalable solution to the probabilistic data association problem, a major challenge in multitarget tracking. Similar to most existing data association algorithms, the SPADA is also based on the conventional data association assumption: Targets either ...

Measurement transformation algorithm for extended target tracking

Signal Processing, 2021
Abstract Extended target tracking algorithms require the estimation of the target's shape in addition to its kinematic properties. The star-convex model can describe the details of the target's shape compared with the traditional elliptical model. The shape estimation based on the star-convex model is a complex nonlinear problem, which also contains ...

Extending time‐to‐target plots to multiple instances

International Transactions in Operational Research, 2018
AbstractTime‐to‐target plots (ttt‐plots) are a useful tool to characterize, evaluate, and compare the behavior of randomized heuristics for a given problem instance of some combinatorial optimization problem. Multiple time‐to‐target plots (mttt‐plots) are their natural extension to sets of multiple instances.

Time-Reversal MUSIC Imaging of Extended Targets

IEEE Transactions on Image Processing, 2007
This paper develops, within a general framework that is applicable to rather arbitrary electromagnetic and acoustic remote sensing systems, a theory of time-reversal "MUltiple Signal Classification" (MUSIC)-based imaging of extended (nonpoint-like) scatterers (targets).

Target-Value Search Revisited (Extended Abstract)

Proceedings of the International Symposium on Combinatorial Search, 2021
This paper addresses the Target-Value Search (TVS) problem, which is the problem of finding a path between two nodes in a graph whose cost is as close as possible to a given target value T. This problem has been previously addressed only for directed acyclic graphs.

Analysis of extended target detectors

Proceedings of the IEEE 1996 National Aerospace and Electronics Conference NAECON 1996, 2002
This paper views the problem of extended target detection as that of detection based on multi-observations, and points out that extended target detection for single pulse is similar to multi-pulses detection for low resolution radar. The only difference between them is that the latter is a process of accumulation along time (from pulse to pulse), while

Target detection: the transition from unresolved to extended targets

Electro-Optical and Infrared Systems: Technology and Applications XVIII and Electro-Optical Remote Sensing XV, 2021
Target detection presents many challenges for military sensor imaging system where there is a strong dependency on the camera resolution. From a performance analysis perspective, the target image is typically considered to be either a fully resolved object or else an unresolved point source.
