32 channel receive head coil
Manufactured by Philips
Sourced in Netherlands
The 32-channel receive head coil is a medical imaging device designed to be used with Magnetic Resonance Imaging (MRI) systems. Its primary function is to receive and amplify the radio frequency (RF) signals generated by the target area during an MRI scan, which are then processed to produce high-quality images of the patient's head and brain.

MRI data were acquired using a 3-Tesla Achieva scanner (Philips Healthcare, Netherlands) equipped with 80 mT/m gradients and a 32–channel receive head coil. Diffusion weighted images were acquired using a single-shot spin-echo echo-planar imaging sequence (repetition time [TR] = 11.8 s, echo time [TE] = 50.1 ms, field of view [FOV] = 220 × 220 mm2, N transversal slices = 60, slice thickness = 2 mm, acquisition matrix = 112 × 110). Diffusion was recorded along 64 directions with a b-value of 1000 s/mm2. Additionally, one non–diffusion–weighted b = 0 s/mm2 scan was performed. To aid with anatomical registration of diffusion weighted images, T1–weighted structural images were acquired with 1 mm isotropic resolution (TR = 8.1 ms, TE = 3.7 ms).
Preprocessing was performed using QSIPrep version 0.12.2 (Cieslak et al., 2021 (link)), which is based on Nipype (Gorgolewski et al., 2011 ). T1–weighted images were corrected for intensity non-uniformity and skull-stripped using ANTs tools (Avants et al., 2011 (link)), then used as a structural reference for registration of diffusion images. To correct diffusion images for head motion and eddy current-induced image distortions, FSL eddy was applied (Andersson and Sotiropoulos, 2016 (link)). FA maps were computed using tools from TractSeg (Wasserthal et al., 2018 (link)).

MRI data acquisition was performed on a 3T whole-body MR scanner (Achieva, Philips Healthcare, Best, the Netherlands), equipped with 80 mT/m gradients and a 32-channel receive head coil. Diffusion data were acquired using a diffusion-weighted single-shot spin-echo echo-planar imaging sequence (ssh SE-EPI sequence) with the following parameters: repetition time (TR) = 6.64 s, echo time (TE) = 53.6 ms, field of view (FOV) = 240 × 240 mm2, 50 contiguous transversal slices, slice thickness = 2.5 mm, acquisition matrix = 96 × 96, SENSE factor = 2.5, partial Fourier encoding = 60%. The slices were positioned parallel to the anterior and posterior commissure defined on a T1-weighted midline sagittal survey image. Diffusion acquisition was performed along 32 directions with a b-value of 1000 s/mm2 and two signal averages (NSA = 2). Additionally, 4 non-diffusion-weighted b = 0 s/mm2 scans were acquired resulting in a scan time of 8 min 31 s. For structural reference and anatomical priors for the tracking algorithm, T1-weighted images were recorded using a three-dimensional magnetization prepared rapid gradient-echo (MP-RAGE) sequence with 1 mm isotropic resolution.

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
