Xiaofeng Niu, Yongyi Yang, Michael A. King, and Miles N. Wernick
Purpose: In previous work, the authors developed and demonstrated the concept of an image reconstruction procedure aimed to unify gated and dynamic nuclear cardiac imaging, which the authors have termed five-dimensional (5D) SPECT. Gated imaging permits the clinician to evaluate wall motion and, th ... [Med. Phys. 37, 5102 (2010)] published Tue Aug 31, 2010.

Purpose: This article considers the problem of reconstructing cone-beam computed tomography (CBCT) images from a set of undersampled and potentially noisy projection measurements.
Methods: The authors cast the reconstruction as a compressed sensing problem based on [script-l] norm minimization con ... [Med. Phys. 37, 5113 (2010)] published Tue Aug 31, 2010.

Purpose: Normal tissue complication probability (NTCP) of the rectum, bladder, urethra, and femoral heads following several techniques for radiation treatment of prostate cancer were evaluated applying the relative seriality and Lyman models.
Methods: Model parameters from literature were used in ... [Med. Phys. 37, 5126 (2010)] published Tue Aug 31, 2010.

Purpose: Microcomputed tomography (micro-CT) is increasingly used as a nondestructive alternative to ashing for measuring bone mineral content. Phantoms are utilized to calibrate the measured x-ray attenuation to discrete levels of mineral density, typically including levels up to 1000 mg HA/cm, w ... [Med.

Hybrid x-ray/optical luminescence imaging: Characterization of experimental conditions
C. M. Carpenter, C. Sun, G. Pratx, L. Xing, and R. Rao
Purpose: The feasibility of x-ray luminescence imaging is investigated using a dual-modality imaging system that merges x-ray and optical imaging. This modality utilizes x-ray activated nanophosphors that luminesce when excited by ionizing photons. By doping phosphors with lanthanides, which emit light in the visible and near infrared range, the luminescence is suitable for biological applications. This study examines practical aspects of this new modality including phosphor concentration, light emission linearity, detector damage, and spectral emission characteristics. Finally, the contrast produced by these phosphors is compared to that of x-ray fluoroscopy.
Measurement and verification of positron emitter nuclei generated at each treatment site by target nuclear fragment reactions in proton therapy
Aya Miyatake, Teiji Nishio,Takashi Ogino, Nagahiro Saijo, Hiroyasu Esumi, and Mitsuru Uesaka
Purpose: The purpose of this study is to verify the characteristics of the positron emitter nuclei generated at each treatment site by proton irradiation.
Thermoacoustic molecular tomography with magnetic nanoparticle contrast agents for targeted tumor detection
Liming Nie, Zhongmin Ou, Sihua Yang, and Da Xing
Purpose: The primary feasibility steps of demonstrating the ability of microwave-induced thermoacoustic (TA) in phantoms have been previously reported. However, none were shown to target a diseased site in living subjects in thermoacoustic tomography (TAT) field so far. To determine the expressions of oncogenic surface molecules, it is quite necessary to image tumor lesions and acquire pathogenic status on them via TAT.
