Registration of renal SPECT and 2.5D US images

Hybrid Integration of Real-time US and Freehand SPECT: Proof of Concept in Patients with Thyroid Diseases

“…Bucki et al used conventional SPECT data to fuse with live US images (6). Galdames et al combined previously acquired SPECT data and previously acquired US images with a separate workstation (8). Studies in which PET/CT was combined with live US have been performed by Ewertsen (7).…”

“…Starting in 2000, this hybrid imaging approach has led to the introduction of positron emission tomography (PET)/computed tomography (CT), single photon emission CT (SPECT)/CT, and PET/ magnetic resonance (MR) imaging in clinical settings (2)(3)(4). Few concepts of linking ultrasonography (US) with nuclear medicine imaging have been presented (5)(6)(7)(8). However, no integrated concept (in terms of two modalities in one device, comparable to a PET/ CT scanner) is available for linking US with nuclear medicine imaging.…”

DMSA-camSPECT/US fusion imaging of children’s kidneys – Proof of feasibility

“…In addition the scope of this approach could be complemented with a new organ since to date solely thyroid, parathyroids and lymph nodes were evaluated [5,6,8,17]. Rare previous evaluations of renal SPECT/US fusion exist but are distinguishable by the way of co-registration or the post hoc software fusion [19,20].…”

Real-time handheld emission spot allocator (rthESA) for simultaneous fusion imaging with ultrasound

“…A few studies have addressed the combination of common SPECT gamma camera images and US images (3,10), however these studies are based on sequential acquisition in two different examinations, the first for functional data and the second for morphological data. The overlay of the two datasets can be performed "live" on US display during examination, or "offline" on separate workstations.…”
