Wu P, Kim K, Severance L, McVeigh E, Pack J
J Appl Clin Med Phys
. 2024 Dec;
26(2):e14593.
PMID: 39625106
Background: Four-dimensional CT is increasingly used for functional cardiac imaging, including prognosis for conditions such as heart failure and post myocardial infarction. However, radiation dose from an acquisition spanning the...

Haneda E, Heukensfeldt Jansen I, Wu P, Pack J, Hsiao A, McVeigh E, et al.
Med Phys
. 2024 Oct;
52(1):131-145.
PMID: 39413309
Background: Cardiac computed tomography (CT) exams are some of the most complex CT exams due to the need to carefully time the scan when the heart chambers are near the...

Li M, Wu M, Pack J, Wu P, Yan P, De Man B, et al.
Med Phys
. 2024 Sep;
51(12):8725-8741.
PMID: 39321385
Background: Recent photon-counting computed tomography (PCCT) development brings great opportunities for plaque characterization with much-improved spatial resolution and spectral imaging capability. While existing coronary plaque PCCT imaging results are based...

Protocol optimization for functional cardiac CT imaging using noise emulation in the raw data domain
Yin Z, Wu P, Manohar A, McVeigh E, Pack J
Med Phys
. 2024 May;
51(7):4622-4634.
PMID: 38753583
Background: Four-dimensional (4D) wide coverage computed tomography (CT) is an effective imaging modality for measuring the mechanical function of the myocardium. However, repeated CT measurement across a number of heartbeats...

Wu P, Tersol A, Clackdoyle R, Boone J, Siewerdsen J
J Med Imaging (Bellingham)
. 2023 Jun;
10(3):033503.
PMID: 37292190
Purpose: Motivated by emerging cone-beam computed tomography (CBCT) systems and scan orbits, we aim to quantitatively assess the completeness of data for 3D image reconstruction-in turn, related to "cone-beam artifacts."...

Zhang X, Sisniega A, Zbijewski W, Lee J, Jones C, Wu P, et al.
Med Phys
. 2023 Mar;
50(5):2607-2624.
PMID: 36906915
Background: Image-guided neurosurgery requires high localization and registration accuracy to enable effective treatment and avoid complications. However, accurate neuronavigation based on preoperative magnetic resonance (MR) or computed tomography (CT) images...

Med Phys
. 2022 Jul;
49(11):6840-6855.
PMID: 35880711
Purpose: To investigate the effects of subject motion and gantry rotation speed on computed tomography (CT) image quality over a range of image acquisition speeds for fan-beam (FB) and cone-beam...

IEEE Trans Med Robot Bionics
. 2022 Apr;
4(1):28-37.
PMID: 35368731
Conventional neuro-navigation can be challenged in targeting deep brain structures via transventricular neuroendoscopy due to unresolved geometric error following soft-tissue deformation. Current robot-assisted endoscopy techniques are fairly limited, primarily serving...
