Custom ASICs in Advancing Medical Imaging Technology

Medical imaging technology is at the heart of modern healthcare diagnostics, allowing doctors to perfect disease detections, calculate conditions, and design treatment plans. The tools have been perfected from X-ray technology to MRIs, CT scans, and ultrasound, and the latest generation is more advanced than its predecessor. However, complexity is the challenge in processing data inexpensively in near real-time.

This is the point where Custom ASICs make all the difference. Below, we delve into how custom ASICs enhance medical imaging technology. In doing this, we shall identify the ASIC design flow and explain why ASIC design consultancy services are crucial for businesses seeking to produce high-performance chips in their devices.

Why Custom ASICs Are Crucial in Medical Imaging?

Medical imaging devices deal with huge amounts of data. Applications like these typically have to be performed in real time to ensure appropriate diagnosis. Real standard processors are often not up to the task and result in failures or poor image quality as a consequence of delay inefficiencies. Application-specific integrated chips are aimed at a specific task, making them perfectly suited for the demanding applications of medical imaging.

Major reasons why custom ASICs are indispensable for the future of medical imaging:

1. Real-time Processing and Efficiency: It is a case with the sheer volumes of data that would be produced from medical imaging devices such as MRI machines, CT scanners, or ultrasound devices. Real-time processing of this load of data is critical for doctors because they rely on imaging to make timely and accurate diagnoses. General-purpose processors have the flexibility, but they usually do not possess the raw power needed to fit into this type of workload without performance sacrifices.

With custom ASICs, algorithms are designed for the purpose of real-time handling of large data streams. Application examples would include MRI machines needing rapid image reconstruction to obtain high-resolution images. In this respect, ASICs are indeed ideal for such applications, allowing very fast, reliable data handling that, in turn, yields clearer, more precise imaging.

2. Power Efficiency for Portable Devices: With portable imaging devices such as hand-held ultrasound machines or wearable medical imaging solutions, power efficiency becomes especially critical. Very often, such portable imaging equipment is applied in emergency situations or in areas with grid access difficulties. General-purpose chips consume a lot of power, which could severely limit the usage of portable devices or degrade the battery life.

Whereas custom ASICs put the concern for energy efficiency as the first preference while designing architecture. Custom ASICs consume lesser amounts of power due to their architecture being designed according to the specific needs of the device that will be operated on a portable device for a long duration using a single charge. This can make a difference between life and death in remote or field-based healthcare when reliable and efficient imaging is in question.

3. Miniaturization and Compact Design: Advances in medical devices, which are the smallest, lightest, and most portable to date, have elicited a significant demand surge. Physicians require apparatuses that are easy to carry and may be applied within various healthcare settings, such as inside a patient’s home. Miniaturization of medical equipment is made possible through incorporating more functionality into reduced physical space using custom ASICs.

Unlike general-purpose processors, which have to use several exterior components to carry out different functions, ASICs can put everything into a single chip, thus significantly making the device smaller. For instance, while portable ultrasound machines of today are much smaller and more powerful than their predecessors, they owe it to the use of custom ASICs.

4. Cost-Effectiveness in the Long Run: Although expensive up-front, the cost of using ASICs is actually much lower than their off-the-shelf counterparts. This is because ASICs can eliminate multiple components and greatly reduce the power consumption of a chip.

And in its use, the custom ASICs get mass-produced. And this again pushes down the cost per unit. For high-volume medical device manufacturers, this may bring out meaningful savings over time, even making the healthcare technology more affordable for hospitals and clinics.

ASIC Design Flow: A Step-by-Step Guide

Design and development of a customized ASIC for medical imaging is a multistep process demanding serious planning and expertise. It ensures that an ASIC design flow produces the final product, optimized for performance as well as power efficiency, at the lowest level of reliability.

1. Definition of Specification: Of all the steps in the ASIC design flow, the first one is defining specifications. In doing so, performance requirements need to be derived, which may include how fast the chip has to process information, the power budget (the amount of energy that it can consume), and the physical size constraints (how large or small the chip can be). These are specifications critical to whether the ASIC can fulfil the demands of the medical device.

Medical imaging typically requires familiarity with the idiosyncratic data transfer speed requirements of the device. A CT scanner may need a single chip that can handle huge streams of data in real time, whereas an ultrasound machine may need an ASIC optimized to save power.

• Design and Simulation: The design phase begins after the specifications are defined. Engineers create a digital version of the ASIC through the use of HDLs such as Verilog or VHDL. Such a model would define the logic and functionality of the ASIC. Upon ascertaining that the chip will perform in the expected manner, simulation tools are applied when the design is completed, to test its performance under a wide range of conditions.

The design and simulation phase prevents costly mistakes later in the flow. It tests design early on, catches errors as they happen, and fixes them before the chip goes to fabrication.

• Synthesis and Optimization: Synthesis transforms the high-level design into a gate-level netlist, which is the netlist of logic gates representing the functionality of the chip. In this stage, power, performance, and area – triple P- optimization occur.

Power and performance optimization is also very critical with medical imaging devices. Therefore, a detailed fine-tuning of the design is done so that the desired specification can be obtained with minimum power consumption and minimum area on the chip.

• Physical Design: With the completion of logic design, the ASIC enters into a physical design phase. Physical design encompasses the placement and routing of all individual components of the ASIC onto a silicon chip. It must ensure that the chip satisfies the total requirements regarding timing, power, and performance within the given physical constraints of the device.

In the case of medical devices, miniaturization typically limits the physical design. The flexibility in the selection of the design leads to the fact that there is scope for integration of the ASIC chip within compact medical devices without compromising performance.

• Fabrication and Testing: Fabrication and Test The final phase of the ASIC design flow is the fabrication and testing of the chip. Based on a correct netlist representation of the hardware design, the foundry creates a physical chip on silicon from the given design. After a chip is fabricated, it undergoes a final set of rigorous testing methods to ensure that the chip indeed meets all the specifications as outlined in the application and related documentation.

Medical applications are among the most sensitive and require to be reliable in the medicinal industry. Chip must, therefore, be tested to an extreme and ensure they can take in a real application in the healthcare industry. The test would be under the environmental conditions as well as ensuring that the chip can adhere to the stated regulations as set by the Healthcare industry for regulatory use.

By using the appropriate ASIC for an existing algorithm in MRI, manufacturers should be able to enhance image quality and reduce scan times and power consumption.
2. CT Scanners: These cross-sectional body images are produced with the help of X-rays in CT scanners. Since the quantity of data coming out of a CT scan is pretty large, fast and efficient processing of raw X-ray data permits the development of useful images from such a scan. The real-time processing of this data stream inside the CT scanner, through custom ASICs, increases the speed and accuracy of the scans while drastically decreasing the energy footprint.
3. Ultrasound Devices: The benefits of engineered ASICs optimized for low power are very helpful in handheld ultrasound devices. These engineered ASICs enable significantly longer battery life and a more compact device without compromising the must-have capabilities for real-time imaging that doctors desire.
4. PET Scanners: Positron Emission Tomography (PET) scanners employ radioactive tracers to perform a body scan. Signals generated by PET scanning have to be processed in real time and accurately. Such is the custom ASIC of PET scanners that makes it possible to diagnose more in less time and hence better health for the patients.
